Which of the following best explains why chemical equations are balanced? during chemical reactions a.) new atoms are produced b.) bonds are made and broken c.) energy is transferred d.) matter is rearranged and why? ?

c.) energy is transferred

Explanation:

The chemical equations are balanced because of the energy conservation principle that states that the total energy of an isolated system remains constant in all chemical reactions, whether you have an exothermic, endothermic or reversible reactions. A chemical reaction by itself is a matter of energy transfer, the combustion process in a lighter, for example, generates a flame that gives out energy in the form of light, heat, and sound.

"ptolemy is, without doubt, the greatest figure in ancient astronomy. he gathered up the wisdom of the philosophers who had preceded him. he incorporated this with the results of his own observations, and illumined it with his theories."
