Question

6co₂ + 6h₂o chlorophyll
plants perform a chemical reaction known as photosynthesis in which light energy is converted into chemical energy in the form of sugars. the chemical equation for photosynthesis is displayed. which statements accurately describe the chemical reaction process that plants undergo? select two correct answers.
no new substances are produced during the process of photosynthesis since it is a chemical reaction.
there are more carbon (c) atoms on the products side of the equation than there are on the reactants side.
a new substance is produced during photosynthesis because photosynthesis is a chemical reaction.
there are fewer hydrogen (h) atoms on the products side of the equation than there are on the reactants side.
the number of oxygen (o) atoms is the same on the reactants and products side of the chemical reaction.
estion 9:
equation describes the chemical reaction that occurs during photosynthesis.
2 + 6h₂o→ c₆h₁₂o₆ + 6o₂
many total atoms does c₆h₁₂o₆ contain?
24

Explanation:

Step1: Recall chemical - reaction basics

In a chemical reaction, new substances are formed. For photosynthesis ($6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6+6O_2$), a new substance (glucose $C_6H_{12}O_6$) is produced.

Step2: Check atom - conservation

According to the law of conservation of mass, the number of each type of atom is the same on both the reactants and products side of a balanced chemical equation. For oxygen: In reactants, $6\times2$ (from $CO_2$) + $6$ (from $H_2O$)=$18$; in products, $6$ (from $C_6H_{12}O_6$)+$6\times2$ (from $O_2$) = $18$.

Answer:

C. A new substance is produced during photosynthesis because photosynthesis is a chemical reaction.
E. The number of oxygen (O) atoms is the same on the reactants and products side of the chemical reaction.
