In your own words, explain what the summary equation tells you about cellular respiration.

Sugar plus oxygen reacts together into carbon dioxide, water, and energy.

Explanation:

What the RxN tells me is that we take in sugar as well as oxygen, combine them together and react, and in turn produce carbon dioxide, water, and energy.

This makes sense, because we eat food and breathe in oxygen, so those are our reactants. When we exhale, we breathe out carbon dioxide and we go use the restroom to get rid of excess H₂O. The energy produced is used for our bodily movements.

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.
