Answer:

<h2>The coefficient of the diatomic oxygen has to be 2.</h2>

Explanation:

The balanced reaction should be like this: 2O_{2} + CH_{4} = CO_{2} + 2H_{2}O

So, as you can see, balance mean that molecules in the reaction has to be equal, the amount of element involved has to be the same, due to the Conservation of the Mass Law.

So, Hydrogen and Oxygen are not balanced in the given expression, that's why we need to add those coefficients.

The concept of atomic masses we can find that the correct answer is:

       c) 101

The atomic mass or mass number of an element is the sum of its protons plus the neutrons that are in the atomic nucleus, the electrons are not taken into account because they have a mass much lower than the masses of protons and neutrons.

   

In the table they indicate that there are 46 protons and 55 neutrons, therefore

          M = #_ {protons} + #_ {neutrons}

          M = 46 +55

          M = 101

In conclusion using the concept of atomic masses we find that the correct answer is:

c) 101

Answer: The ratio of carbon to bromine atoms  in the molecule is 3:1

Explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions.

Chemical formula shows the elements in a compound and the relative proportions of those elements.

The chemical formula given for the compound is C_3H_6BrCl which means the ratio of carbon to bromine atoms is 3: 1.

Thus the ratio of carbon to bromine atoms  in the molecule is 3:1
