Look at the following reaction. select the option that best applies to the reaction.

the number of atoms in the product is greater than the number of atoms in the reactant.
2kclo3 < => 2kcl=3o2
a. the number of atoms in the product is greater than the number of atoms in the reactant.
b. the number of atoms in the product is less than the number of atoms in the reactant.
c. the number of atoms in the product is the same number of atoms in the reactant.
d. the number of atoms in the reactant is less than the number of atoms in the product.

- C. The number of atoms in the product is the same number of atoms in the reactant.

Explanations:- Chemical equations obey law of mass conservation of matter. According to this law, " Matter is neither created nor destroyed.

So, to obey this law, chemical reactions must be balanced. A balanced chemical equation means it has equal number of atoms of each element on both sides and so the correct statement is C.

The given balanced equation has two potassium, two chlorine and six oxygen atoms on each side and so it is balanced.

dynamic equilibrium is the answer.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
