Answer

Explanation:

Step1: Analyze $C_2H_4O_2$

The sub - scripts indicate the number of atoms of each element. There are 2 carbon (C) atoms, 4 hydrogen (H) atoms and 2 oxygen (O) atoms.

Step2: Analyze $Mg(OH)_2$

The sub - script outside the parentheses multiplies the atoms inside. For magnesium (Mg), there is 1 atom. For oxygen (O), there are 2 atoms (since the sub - script 2 multiplies the 1 O in OH), and for hydrogen (H), there are 2 atoms.

Answer:

Element C H O
How many atoms 2 4 2
Element Mg O H
How many atoms 1 2 2
