Answer:Adding heat to a solid will definitely melt it.

Example: let's say we have a pack of Hershey's chocolate we take it and leave it outside in the heat.what will happen to it? it will melt 100%

the majority of solids melt. It depends on how solid it is.

Example 2 scenario: lets say we have a penny (a solid) it will melt but with a much higher temperature

the melting temperature for the penny is 1984.32 °F which is extremely high.

lets go back to the previous chocolate example--->

before the chocolate melted it wasnt as hard as the penny. the melting temperature would be much lower compared to the penny. the melting temperature for chocolate is 85°F-93°F.

Why do harder solids have a higher melting point than less-hard solids?

the reason for this is density. The penny is much dense than the chocolate.

How is a penny more dense than chocolate?

lets say we have chocolate (before it melted it was a solid) we are able to actually bite and chew the chocolate; but you are unable to bite and chew a copper coin. the reason for this is that copper is much more dense than chocolate.

it will NOT evaporate because the temperature for liquid evaporation is 212° F.

The given reaction sequence suggests the use of PPh3 followed by BuLi to form a nucleophilic species that can react with 3-pentanone and Br.

The first step involves the formation of a phosphonium ylide intermediate by the reaction of PPh3 with BuLi. In the second step, the ylide acts as a nucleophile and attacks the carbonyl group of 3-pentanone to form a betaine intermediate. The final step involves the reaction of the betaine with Br to give the desired product.

The major organic product formed in this reaction sequence is (E)-1-bromo-3-(phenyl(phenyl)methylidene)butan-1-one. This is because the reaction proceeds via an SN2 mechanism, which leads to the formation of an alkene with an E configuration. The systematic IUPAC name of the product is (E)-1-bromo-3-(phenyl(phenyl)methylidene)butan-1-one.

In this name, "E" indicates the configuration of the double bond, "1-bromo" indicates the presence of a bromine atom on the first carbon, "3-(phenyl(phenyl)methylidene)" indicates the presence of a substituted phenyl group attached to the third carbon, and "butan-1-one" indicates the presence of a ketone group on the first carbon of a four-carbon chain.

Observation and questioning are the two initial steps of the scientific method, and they are closely connected. Observation refers to gathering information and data about a natural phenomenon or a specific problem, while questioning refers to developing an inquiry about what has been observed.

In other words, observation leads to questioning because as scientists observe something, they notice patterns, relationships, and discrepancies that raise questions about what is happening and why. These questions then serve as a guide for further investigation and experimentation, leading to the development of hypotheses and theories.

Furthermore, the quality of the observation directly influences the type of questions that can be formulated. A more precise and accurate observation will lead to more focused and specific questions, while vague observations can lead to ambiguous and unclear questions.

In summary, the observation and questioning steps of the scientific method are interconnected and essential for the development of scientific knowledge. Accurate and detailed observations lead to well-formulated questions that guide scientific inquiry and experimentation, leading to the development of hypotheses and theories.

Answer:

he correct equilibrium constant expression (Keq) for the given equation is:

Keq = ([HCl]^4 [O2]) / ([Cl2]^2 [H2O]^2)

Where [HCl], [O2], [Cl2], and [H2O] represent the equilibrium concentrations of the respective species in the balanced equation.

Note that the Keq expression includes only the concentrations of the gases in the equilibrium mixture, and the coefficients in the balanced equation are used as exponents to represent the stoichiometry of the reaction.

([HCl]⁴ [O[tex]_2[/tex]]) / ([Cl[tex]_2[/tex]]² [H[tex]_2[/tex]O]²)  is the correct equilibrium constant expression for this equation. The reaction quotient value obtained from the expression describing chemical equilibrium.

The reaction quotient value obtained from the expression describing chemical equilibrium is the equilibrium constant. It is influenced by temperature and ionic strength and is unaffected by the amounts of product and reactant in a solution.

Reactions which attain heterogeneous equilibrium have more than one phase. Typically, only two phases—such as gaseous and liquid phases and solids and liquids—are present. The expression for equilibrium does not include solids.

Keq = ([HCl]⁴ [O[tex]_2[/tex]]) / ([Cl[tex]_2[/tex]]² [H[tex]_2[/tex]O]²)

The balanced chemical equation for the reaction between Pb(NO3)2 and NaCl is:

Pb(NO3)2 + 2NaCl -> PbCl2 + 2NaNO3

In order for a chemical equation to be balanced, the number of atoms of each element in the reactants must be equal to the number of atoms of each element in the products.

In the given equation, there are one Pb atom, two Na atoms, two Cl atoms, two N atoms, and six O atoms on the left-hand side (reactants) of the equation. On the right-hand side (products) of the equation, there are one Pb atom, two Na atoms, two Cl atoms, two N atoms, and six O atoms.

To balance the equation, we need to adjust the coefficients (the numbers in front of the chemical formulas) so that the number of atoms of each element is the same on both sides. In this case, we need to add a coefficient of 2 in front of NaCl on the reactant side to balance the number of Cl atoms, which also adds 2 Na and 2 NO3 atoms. This gives us:

Pb(NO3)2 + 2NaCl -> PbCl2 + 2NaNO3

Answer:

0.359 L or 359 mL of O2 gas will be produced from the given reaction at STP

Explanation:

The balanced chemical equation for the decomposition of KNO3 is:

2 KNO3 (s) → 2 KNO2 (s) + O2 (g)

From this equation, we can see that 2 moles of KNO3 produce 1 mole of O2. Therefore, we need to calculate the number of moles of KNO3 we have and use the mole ratio to find the number of moles of O2 produced.

First, we need to convert the mass of KNO3 given to moles:

moles of KNO3 = mass of KNO3 / molar mass of KNO3

The molar mass of KNO3 is 101.1 g/mol (39.1 g/mol for K, 14.0 g/mol for N, and 3 x 16.0 g/mol for 3 O atoms), so we have:

moles of KNO3 = 3.25 g / 101.1 g/mol = 0.0321 mol

Now we can use the mole ratio from the balanced equation to find the number of moles of O2 produced:

moles of O2 = 0.5 x moles of KNO3

moles of O2 = 0.5 x 0.0321 mol = 0.01605 mol

Finally, we can convert the number of moles of O2 to volume at STP using the ideal gas law:

V(O2) = n x RT/P = (0.01605 mol)(0.0821 L·atm/(mol·K) x 273.15 K)/(1 atm) = 0.359 L

Therefore, 0.359 L or 359 mL of O2 gas will be produced from the given reaction at STP.

Answer:

molecular formula = C₂₇H₃₆O₄₅

Explanation:

In order to find the molecular formula of a compound from its empirical formula, we need to know the number of "empirical formula units" that are in the molecular formula.

To find the number of empirical formula units, n,  we use the following formula:

[tex]\boxed{\mathrm{n = \frac{molar \ mass}{empirical \ formula \ mass}}}[/tex].

The empirical formula mass is simply the molar mass of the compound that is represented by the empirical formula. Therefore, in this case,

Empirical formula mass of C₃H₄O₅ = (12 × 3) + (1 × 4) + (16 × 5)

                                                         = 36 + 4 + 80

                                                         = 120

Next, we can find the value of n using the above formula:

n = [tex]\frac{1080.54}{120}[/tex]

  = 9.00

Now that we know the number of empirical formula units (n) present in the molecular formula, we simply have to multiply the number of each element present in the empirical formula by n:

Molecular formula = (empirical formula)ₙ

⇒ Molecular formula = (C₃H₄O₅)₉

                                   = C₂₇H₃₆O₄₅

Therefore, the molecular formula of the secret compound is C₂₇H₃₆O₄₅.

Explanation:

Answer: Melting point determination can be used to distinguish between a pure sample and an impure sample because the presence of impurities will usually lower the melting point of a substance.

Explanation:

When a pure substance is heated, it will begin to melt at a specific temperature known as its melting point. However, when an impure substance is heated, the presence of impurities will cause the melting point to decrease and the substance to melt over a range of temperatures.

Therefore, by comparing the melting point of a sample to the known melting point of a pure substance, we can determine whether the sample is pure or impure. If the sample has the same melting point as the pure substance, then it is likely pure. However, if the sample melts over a range of temperatures or at a lower temperature than the pure substance, then it likely contains impurities.

Explanation:

The balanced chemical equation for the combustion of butane is:

2C4H10 + 13O2 → 8CO2 + 10H2O

From the equation, we can see that for every 2 moles of butane that react, 10 moles of water are produced.

To find the mass of water produced when 5.13g of butane reacts, we need to first convert the mass of butane to moles:

5.13g of butane / molar mass of butane (58.12 g/mol) = 0.0883 moles of butane

Since there is excess oxygen, we can assume that all of the butane will react completely, so we can use the mole ratio from the balanced equation to find the number of moles of water produced:

0.0883 moles of butane × (10 moles of water / 2 moles of butane) = 0.4415 moles of water

Finally, we can convert the moles of water to grams:

0.4415 moles of water × molar mass of water (18.02 g/mol) = 7.95g of water

Therefore, the mass of water produced when 5.13g of butane reacts with excess oxygen is 7.95g.

First, we need to convert the toxicity value from mg/kg to mg for a 70 kg adult:

Toxic dose for a 70 kg adult = 12,000 mg/kg x 70 kg = 840,000 mg

Next, we need to calculate the number of moles of 7-UP in one can:

Concentration of 7-UP in one can = 0.012 M

Volume of one can = 330 mL = 0.33 L

Number of moles of 7-UP in one can = concentration x volume = 0.012 mol/L x 0.33 L = 0.00396 mol

Finally, we can calculate the number of cans of 7-UP a 70 kg adult would have to drink to reach a toxic dose:

Number of cans of 7-UP = toxic dose / (number of moles in one can x molecular weight of 7-UP)

Molecular weight of 7-UP = 338.14 g/mol

Number of cans of 7-UP = 840,000 mg / (0.00396 mol x 338.14 g/mol) ≈ 619 cans

Therefore, a 70 kg adult would have to drink approximately 619 cans of 7-UP to reach a toxic dose.

Nuclear fission is a process where a heavy atomic nucleus is split into two or more lighter nuclei, releasing a large amount of energy.

1.Uranium-235 fissioned by neutron:

U-235 + neutron → Kr-92 + Ba-141 + 3 neutrons + energy

2.Plutonium-239 fissioned by neutron:

3.Californium-252 fissioned by neutron:

Cf-252 + neutron → 2 Sm-126 + 3 neutrons + energy.

Nuclear fission is a process in which a heavy atomic nucleus (such as uranium-235, plutonium-239, or californium-252) is split into two or more lighter nuclei (such as krypton-92 and barium-141), along with the release of a large amount of energy in the form of radiation and kinetic energy of the resulting particles. This process is typically initiated by the absorption of a neutron by the heavy nucleus, which causes it to become unstable and split apart.

In the fission reaction, the mass of the products is slightly less than the mass of the reactant nucleus, due to the conversion of some mass into energy according to Einstein's famous equation [tex]E=mc^2[/tex], where E is the energy released, m is the mass lost, and c is the speed of light.

The energy released in nuclear fission reactions is much greater than that released in chemical reactions, making nuclear fission an attractive source of energy for power generation. However, fission reactions can also be dangerous if not properly controlled, as the released energy can cause explosions or release dangerous radiation.

Answer:

At STP (standard temperature and pressure), one mole of any gas occupies 22.4 liters. Therefore, to determine the number of moles of helium gas that would occupy 60 L at STP, we can use the following conversion factor:

1 mole He gas = 22.4 L He gas at STP

So, we can set up the following proportion:

x moles He gas / 60 L He gas = 1 mole He gas / 22.4 L He gas

where x is the number of moles of helium gas we want to find.

To solve for x, we can cross-multiply and simplify:

x moles He gas = (60 L He gas)(1 mole He gas / 22.4 L He gas)

x moles He gas = 2.68 moles He gas (rounded to two decimal places)

Therefore, 2.68 moles of helium gas would occupy 60 L at STP.

The rate law can only be determined experimentally through the method of initial rates or by determining the order of the reaction with respect to each reactant. Therefore, the correct answer is D. none of these.

In chemical kinetics, the rate law is an equation that relates the rate of a chemical reaction to the concentration of reactants. It is usually determined experimentally by measuring the initial rates of the reaction under different conditions of reactant concentration, temperature, and pressure.

The general form of a rate law for a reaction involving one or more reactants can be written as follows:

rate = k[A]x[B]y[C]z...

where rate is the rate of the reaction, k is the rate constant, [A], [B], [C]... are the concentrations of the reactants, and x, y, z... are the orders of the reaction with respect to each reactant.

In the given reaction X → Z, we are not given any information about the specific reaction mechanism or the dependence of the rate on the concentrations of X and Z. Therefore, it is not possible to determine the rate law without experimental data.

To determine the rate law experimentally, we would need to measure the initial rates of the reaction under different conditions of reactant concentrations and analyze the data to determine the orders of the reaction with respect to each reactant.
