Question

name each element and the number of atoms of that element in one molecule of acetic acid (c₂h₄o₂), which is the active ingredient of vinegar.

Explanation:

Step1: Identify carbon

The symbol C represents carbon. There are 2 carbon atoms in one molecule of acetic acid $\text{C}_2\text{H}_4\text{O}_2$.

Step2: Identify hydrogen

The symbol H represents hydrogen. There are 4 hydrogen atoms in one molecule of acetic acid $\text{C}_2\text{H}_4\text{O}_2$.

Step3: Identify oxygen

The symbol O represents oxygen. There are 2 oxygen atoms in one molecule of acetic acid $\text{C}_2\text{H}_4\text{O}_2$.

Answer:

Carbon: 2 atoms; Hydrogen: 4 atoms; Oxygen: 2 atoms
