Question

1. the chemical equation for photosynthesis is shown below. 6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂ part a which element is found in the greatest total number of atoms on the reactant side? hydrogen oxygen carbon

Explanation:

Step1: Count carbon atoms

In $6CO_2$, there are $6\times1 = 6$ carbon atoms.

Step2: Count hydrogen atoms

In $6H_2O$, there are $6\times2=12$ hydrogen atoms.

Step3: Count oxygen atoms

In $6CO_2$, there are $6\times2 = 12$ oxygen atoms, and in $6H_2O$, there are $6\times1=6$ oxygen atoms. So in total on the reactant - side, there are $12 + 6=18$ oxygen atoms.

Answer:

Oxygen
