6. Challenge: To balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow.

No, the equation is not balanced

Explanation:

The complete question is

Challenge: To balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow.

C6H12O6 + O2 ⇒ CO2 + H2O

A. Is the formula balanced as written? Why or why not?

Solution -

No, the equation is not balanced. The balanced chemical reaction of cellular respiration process is C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O

The number of atoms  of each element must be same on both the sides of the equation.

In the equation - C6H12O6 + O2 ⇒ CO2 + H2O, there are 6 carbon on left side of equation while only one carbon on the right side of equation. Like wise there are 12 hydrogen atom on LHS and 2 hydrogen atom on RHS. Oxygen number is also unbalanced.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
