how many atoms of each element are in the chemical formula ca(oh)₂?\n1 calcium, 1 oxygen, and 1 hydrogen\n1…

Explanation:

Step1: Analyze calcium atoms

The symbol Ca has no sub - script outside the parentheses, so there is 1 calcium atom.

Step2: Analyze oxygen atoms

The O in (OH) has a sub - script of 1 inside the parentheses and a 2 outside the parentheses. So the number of oxygen atoms is 1×2 = 2.

Step3: Analyze hydrogen atoms

The H in (OH) has a sub - script of 1 inside the parentheses and a 2 outside the parentheses. So the number of hydrogen atoms is 1×2 = 2.

Answer:

1 calcium, 2 oxygen, and 2 hydrogen
