Question

in photosynthesis, which of the following are reactants? select all chemical formulas that apply.
a) h₂o
b) c₆h₁₂o₆
c) o₂
d) energy
e) co₂

Explanation:

The general equation for photosynthesis is \(6CO_2 + 6H_2O+energy
ightarrow C_6H_{12}O_6 + 6O_2\). Reactants are the substances that start a chemical reaction. In this equation, \(H_2O\) (water), \(CO_2\) (carbon - dioxide) and energy (usually from sunlight) are the reactants. \(O_2\) (oxygen) and \(C_6H_{12}O_6\) (glucose) are products.

Answer:

A. \(H_2O\), D. energy, E. \(CO_2\)
