Chemical reactions can occur when substances are mixed with or dissolved in water. Chemical reactions are represented by chemical equations. In a chemical equation, the reactants are shown on the left side and the products are shown on the right side. The reactants and products are separated by an arrow.
This image illustrates the chemical reaction that occurs when hydrogen (\( {H}_{2} \)) and oxygen (\( {O}_{2} \)) react to produce water. In this reaction, the reactants are \( {H}_{2} \) and \( {O}_{2} \). The product is \( {H}_{2}{O} \).
Question
Photosynthesis is a chemical reaction where plants take carbon dioxide and water and make sugar molecules that they can use for food and oxygen. Photosynthesis is represented by the equation:
\( \displaystyle {C}{O}_{2} + {H}_{2}{O\ \rightarrow \ }{C}_{6}{H}_{12}{O}_{6} + {O}_{2} \)
What are the reactants and products in the photosynthesis reaction?
The reactants are carbon dioxide (CO2) and water (H2O).
The products are sugar(C6H12O6) and oxygen (O2).
