Which of the following is an example of a decomposition reaction? a. photosynthesis b. digestion c. polymerization d. exchange of ions between two compounds digestion is an example of a decomposition reaction.

Option B, Digestion

Explanation:

As the name suggest in a decomposition reaction a bigger chemical substance is broken down into simpler chemical substances.

For instance, during the process of digestion carbohydrates (CHO compounds) such as starch decomposes into glucose. Like wise protein decomposes into amino acids and complex fat molecule decomposes into simpler fat molecules. Thus, digestion is a decomposition reaction.

Thus, option b, digestion is the correct answer.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
