For the second to last problem the coefficients is  1, 5, 3, and 4 and the last problem all the coefficients are 1's

Explanation:

For the second to last problem you put 3 next to CO₂ so C is 3 on both sides. Then you put 4 next to H₂O because H will then be 8 on both sides. Lastly you put 5 next to O₂ which will make 10 on the reactant side. On the product side the 3 next to CO₂ will make O on the product side 6 and the 4 next to H₂O will make O on the product side 4. You will then add both together and it will make 10, which will make 10 on both sides. Hope this helps!

An empirical formula is a type of chemical formula that shows the simplest ratio of elements present in a compound, rather than the total number of atoms.

What are Atoms?

Atoms are the smallest indivisible particles that make up all matter in the universe. They consist of a nucleus containing protons and neutrons, surrounded by a cloud of electrons. Atoms make up all elements, which are the building blocks for all other forms of matter.

Step 1: Calculate the atomic mass of carbon, hydrogen, oxygen, and nitrogen.

Carbon: 12.011 g/mol

Hydrogen: 1.008 g/mol

Oxygen: 15.999 g/mol

Nitrogen: 14.007 g/mol

Step 2: Convert the mass of each element to moles.

Carbon: 83.884 g / 12.011 g/mol = 6.983 mol

Hydrogen: 10.486 g / 1.008 g/mol = 10.381 mol

Oxygen: 18.640 g / 15.999 g/mol = 1.164 mol

Nitrogen: (200.00 g - (83.884 g + 10.486 g + 18.640 g)) / 14.007 g/mol = 6.871 mol

Step 3: Divide each mole value by the smallest mole value to obtain the simplest whole number ratio.

Carbon: 6.983 mol / 6.983 mol = 1

Hydrogen: 10.381 mol / 6.983 mol = 1.485

Oxygen: 1.164 mol / 6.983 mol = 0.167

Nitrogen: 6.871 mol / 6.983 mol = 0.985

The empirical formula of the compound is CHNO.

Answer:

Physical geography is one of the two fields of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere

Explanation:

frequency = 1 wave/10s = 0.1 Hz

wavelength = 5.8 m

speed = wavelength × frequency

= (5.8 m)(0.1 Hz)

= 0.58 m/s

The molarity of 2. 50 m NaCl solution is 2.68 molal and 48. 2 percent by mass KBr solution is 7.82 m.

Molality = moles solute / kg solvent  

Assume we have 1000 ml of solution.

1000 ml ₓ 1.08 g/ml = 1080 g

Now find the mass of NaCl:

2.50 M NaCl = 2.50 mol/L and 2.50 mol/L x 1 L = 2.50 moles of NaCl

molar mass NaCl = 58.4 g/mol, therefore mass NaCl present = 2.50 mol ₓ 58.5 g/mol = 146 g NaCl

Now find the mass of H₂O:

grams H₂O present = 1080 g - 146 g = 934 g H2O = 0.0.934 kg

We now have moles NaCl and kg H₂O

Molality  = 2.50 mol / 0.934kg = 2.68 molal

48.2% by mass of KBr means 48.2 g KBr / 100 g solution

To find molality, we need moles of KBr and kg of H₂O.  We can easily find he moles of KBr from the mass and the molar mass.

If we have 100 g solution, 48.2 g is KBr so the rest is H₂O.

100 g - 48.2 g = 51.8 g H₂O and this is equal to 0.0518 kg H₂O

Moles KBr = 48.2 g KBr ₓ 1 mol KBr/119 g = 0.405 moles KBr

Molality = 0.405 moles KBr / 0.0518 kg H₂O = 7.82 m

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the correct option is option C.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

The statement "atoms have a small, dense nucleus" is true.  A few alpha particles shot at gold foil bounce in the opposite direction is the evidence.

Therefore, the correct option is option C.

Explanation:

14) We need to find the # of moles of NaOH in 3.5 L solution. Note: 1 M = 1 mol/Ll

(3.00 mol NaOH/1 L)(3.5 L) = 10.5 mol NaOH

Next we need find the volume of 19.4M NaOH solution that contains 10.5 mol NaOH:

(10.5 mol NaOH)×(1 L NaOH/19.4 mol NaOH)

= 0.541 L NaOH

This means that 0.541 L (541 mL) of 19.4M NaOH solution must be diluted to 3.5 L in order to get 3.00M NaOH solution.

15) 425 mL (0.425 L) of 0.105M HCl solution contains

(0.105 mol HCl/1 L)×(0.425 L) = 0.0446 mol HCl

so when enough water is added to 1L, the molarity becomes

0.0446 mol HCl/1 L = 0.0446M HCl

16) CaBr2 ---> Ca^+2 + 2Br^-1

For every Ca^+2 ion in the solution, you have 2 Br^-1 ions

If the concentration of CaBr2 is 6 mol/L (or 6M),.then the concentration of Br^-1 irons is

[Br^-1] = 2×[Ca^+2] = 2×(6 mol/L) = 12 mol Br^-1/L

17) The reason you won't need 1.0 L of water is that part of the volume of the solution is taken up by the NaOH so you will always need slightly less than 1 L.

Commission can be defined as an amount of money earned based on how much a salesperson sell.

Answer:

There are several methods that can be used to prevent or slow corrosion:

Coatings: Applying a protective coating to a metal surface can prevent corrosion by creating a barrier between the metal and the environment. Common types of coatings include paint, galvanizing, and electroplating.

Cathodic protection: Cathodic protection involves applying a current to a metal surface in order to reduce the potential difference between the metal and its environment. This can help to prevent corrosion by reducing the electron flow that drives the corrosion reaction.

Inhibitors: Corrosion inhibitors are chemical substances that can be applied to a metal surface to slow or prevent corrosion. These substances work by reacting with the metal surface or the environment to form a protective film or layer.

Passivation: Passivation is a process that involves removing surface contaminants and oxide layers from a metal surface in order to improve its corrosion resistance. This can be achieved through chemical or mechanical means.

Materials selection: Choosing corrosion-resistant materials for specific applications can help to prevent or slow corrosion. For example, stainless steel is a commonly used material for corrosive environments because of its high resistance to corrosion.

Environmental control: Controlling the environment in which a metal object is used can also help to prevent or slow corrosion. For example, reducing humidity or keeping a metal object dry can help to prevent corrosion.

Maintenance: Regular maintenance, such as cleaning and inspection, can help to identify and address corrosion issues before they become severe. This can include removing corrosion products, repairing damage, and applying protective coatings as needed.

Answer:

Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Many people believe they are “feeding” a plant when they put it in soil, water it, or place it outside in the Sun, but none of these things are considered food. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Answer:

energy is of course required for photosynthesis to occur as photosynthesis is self is the process of plants of green plants to make food or to provide food for themselves in the presence of sunlight carbon dioxide and using water from the soil in the definition you can also say that sunlight is needed for photosynthesis to take place and some light is a form of energy which is solar energy so energy is required for photosynthesis to occur

Answer:

Nonmetals tend to gain electrons while metals tend to lose electrons.

Explanation:

The statement that describes the reaction of nonmetals and metals is "Nonmetals tend to gain electrons while metals tend to lose electrons."

Metals (such as copper and aluminum) are good heat and thermal conductors, whereas nonmetals (such as phosphorus and sulphur) are considered to be insulators.

When a metal reacts with a nonmetal, the metal loses electrons while the nonmetal gains electrons. In order to achieve their nearest noble gas configuration, elements can gain or lose electrons. The formation of ions for the octet's completion aids in their stability. Metals lose electrons to complete their octet in a reaction between metals and nonmetals, while nonmetals acquire electrons to complete their octet.

When metal atoms produce ions, they lose electrons from their outer shell; the ions are positive because they contain more protons than electrons. The ions that are generated have complete outer shells. The ions have a full outer shell and have the electrical structure of a noble gas (group zero element).

Nonmetals are found further to the right on the periodic table and have high ionization energy and electron affinities, making them comparatively easy to absorb electrons and difficult to lose them. They also have a higher number of valence electrons, and are on the verge of completing an octet of eight electrons.

Hence the correct answer is nonmetals tend to gain electrons while metals tend to lose electrons.

Answer:

0.0272 moles

Explanation:

The number of moles of acid that were neutralized can be found by multiplying the volume of the base (in liters) by its concentration (in moles/liter) and then multiplying that value by the stoichiometric coefficient of the acid in the balanced chemical equation for the neutralization reaction.

To begin, we need to convert the volume of the base from milliliters to liters.

50.40 mL = 0.0504 L

Next, we can multiply the volume of the base (in liters) by its concentration (in moles/liter) to find the number of moles of base used in the titration.

0.0504 L * 0.542 M = 0.0272 moles

Since this is a neutralization reaction between a monoprotic acid and a strong base, the acid:base ratio is 1:1.

So the acid that has been neutralized is also 0.0272 moles.
