Answer:

1. B = 1.13M

2. A. 8.46%

3. D = 0.0199

Explanation:

1. Molarity of a a solution = number of moles of solute/ volume of solution in L

Number of moles of solute = mass of solute/molar mass of solute

Molar mass of NaC₂H₃O₂ = 82 g/mol, mass of NaC₂H₃O₂ = 245 g

Number of moles of NaC₂H₃O₂ = 245 g / 82 g/mol = 2.988 moles

Molarity of solution = 2.988 mols/ 2.65 L = 1.13 M

2. Percentage by mass of a substance = mass of substance /mass of solution × 100%

Mass of 2.65 L of water = density × volume

Density of water = 1 Kg/L = 1000 g/L; volume of waterb= 2.65 L

Mass of water = 1000 g/L × 2.65 L = 2650 g

Mass of solution = mass of water + mass of solute = 245 + 2650 =2895 g

Percentage by mass of NaC₂H₃O₂ = 245/2895 × 100% = 8.46%

3. Mole fraction of NaC₂H₃O₂ = moles of NaC₂H₃O₂/moles of solution

Moles of water = mass /molar mass

Mass of water = 2650 g; molar mass of water = 18 g/mol

Moles of water = 2650 g / 18 g/mol = 147.222 moles

Moles of solution = moles of solute + moles of water = 147.222 + 2.988 = 150.21

Moles of NaC₂H₃O₂ =2.988 moles

Moles fraction of NaC₂H₃O₂ =2.988/150.21 = 0.0199

Answer:

the molecular formula of the soap is C₅₄H₁₀₂O₆

Explanation:

Given;

composition of carbon, C = 76.5%

composition of oxygen, O = 11.3%

Composition of hydrogen, H = 12.2%

The empirical formula is calculated as follows;

C:    76.5% / 12          O:  11.3% / 16             H:   12.2% / 1

     =  6.375                  =   0.706                   =  12.2

Divide through by the least number (0.706);

    =  6.375/0.706           = 0.706 / 0.706          =  12.2 / 0.706

   =  9                              =    1                              =  17

The empirical formula = C₉H₁₇O

The molecular formula is calculated as follows;

(C₉H₁₇O)n = 847

(9 x 12    +   17 x 1      +  16 x 1)n   = 847

(108 + 17 + 16)n = 847

141n = 847

n = 847/141

n = 6

The molecular is (C₉H₁₇O)6 =  C₅₄H₁₀₂O₆

Therefore, the molecular formula of the soap is C₅₄H₁₀₂O₆

[tex]m_{CO_2}=0.88g[/tex]

Explanation:

Hello there!

In this case, since we are talking about a decomposition reaction whereby calcium carbonate is decomposed to calcium oxide and carbon dioxide according to the following chemical equation:

[tex]CaCO_3\rightarrow CaO+CO_2[/tex]

Next, we must recall the law of conservation of mass which states that matter cannot be neither created nor destroyed so the mass of calcium carbonate equal the addition of the mass of both calcium oxide and carbon dioxide:

[tex]m_{CaCO_3}=m_{CaO}+m_{CO_2}[/tex]

Which must be solved for the mass of carbon dioxide as we are given those of calcium carbonate and calcium oxide:

[tex]m_{CO_2}=m_{CaCO_3}-m_{CaO}\\\\m_{CO_2}=2.00g-1.12g\\\\m_{CO_2}=0.88g[/tex]

ok so it would help if I knew the marks but 1 mole = 1000L so if the volume was 31L then if you convert you will get that answer

The moles of gas at the given sample of gas is 1.7 moles.

Ideal gas equation gives idea about the behavior of gas at different condition & represented as:

PV = nRT, where

On putting all these values, we get moles as:

n = (1.2)(31) / (0.082)(256) = 37.2 / 20.9

n = 1.7 moles

Hence required moles of gas is 1.7 mole.

Answer:

Photosynthesis is the process takes place in green plants in which the plants convert the carbon dioxide and water into the sugar molecule and oxygen in presence of the sunlight. The sunlight is trapped by the chlorophyll pigment, carbon dioxide uptake is facilitated by the stomata present on the leaves in the epidermis.

The water moves from the roots to the leaves and stem where it is used for photosynthesis and transpiration. The movement of water is through the xylem and sugar is move through the phloem from the leaves to a different part of the plant for nutrition and further process.

Answer:

38.75 L

Explanation:

From the question,

Applying Boyles Law,

PV = P'V'....................... Equation 1

Where P = Original pressure of the Argon gas, V = Original Volume of Argon gas, P' = Final pressure of Argon gas, V' =  Final Volume of Argon gas.

make V the subject of the equation

V = P'V'/P.................... Equation 2

Given: P = 34.6 atm, V' = 456 L, P' = 2.94 atm.

Substitute these values into equation 2

V = (456×2.94)/34.6

V = 38.75 L

Answer is: at lower temperatures the reaction rate would decrease. The lower is the temperature, the slower the reaction becomes. ... Because this is exothermic reaction (enthalpy is less than zero), at lower temperatures, the equilibrium is in favor of ammonia, but the reaction doesn't proceed at a detectable rate.

Hi,

let us go through the question again

N2 + 3H2 ⇌ 2NH3 + energy  

Explain the problem surrounding the ammonia-making process in terms of chemical equilibrium.

So I would approach this question on the basis of effect of each of the reactants and products concentration on the equilibrium synthesis of ammonia.

If the concentration of any reactant is increased, the yield of ammonia is increased.

If the concentration of ammonia is reduced by removing it as it forms, the yield will as well be increased.

This reaction also yields heat meaning it is an exothermic reaction, so when we increase the temperature, the yield will be reduced. Hence it is favored by low temperature.

Answer: C) the rate of forward reaction is not equal to the rate of backward reaction. This should be the answer.

Answer:

Any change that increases the number of particles in a system increases entropy because it increases the randomness and disorder of the system.

Explanation:

Imagine dropping a glass pitcher on a hard surface. The pitcher breaks into numerous shards. If the shards were collected and dropped again, they would tend to break into smaller shards; they would not reassemble themselves into a pitcher. In the universe, there is a tendency for order to be replaced with disorder. This tendency is related to a concept called entropy. The formal definition of entropy is a measure of the degree of randomness and disorder in a system.

Explanation:

Answer:

should you prove this or explain or pick the correct answer

According to the kinetic molecular theory, collisions between gas particles in a sample of an ideal gas: Transfer energy between the gas particles. Hence, option 4 is correct.

According to kinetic theory of gases, when gas particles collide with each other, they transfer energy between themselves. Some collisions will result in the transfer of kinetic energy from one particle to another, while others may result in a transfer of potential energy due to the intermolecular forces between the particles.

However, the total energy of the gas particles is conserved during these collisions, so there is no net loss or gain of energy by the gas sample as a whole.

The kinetic molecular theory also states that ideal gas particles do not have any significant attractive or repulsive forces between them, so option 2 is incorrect.

Additionally, collisions between gas particles do not increase the energy content of the gas sample (option 1) or result in a net loss of energy by the gas sample (option 3).
