Answer 1

1 calcium, 2 oxygen, and 2 hydrogen

1 calcium, 2 oxygen, and 2 hydrogen

1 calcium, 2 oxygen, and 2 hydrogen

1 calcium, 2 oxygen, and 2 hydrogen

1 calcium, 2 oxygen, and 2 hydrogen

1 calcium, 2 oxygen, and 2 hydrogen

1 calcium, 2 oxygen, and 2 hydrogen

XD

Step-by-step explanation:

Answer 2

Option B. 1 calcium, 2 oxygen, and 2 hydrogen

Step-by-step explanation:

The number of each atoms present in Ca(OH)2 can be summarised as follow:

Calcium (Ca) = 1

Oxygen (O) = 2

Hydrogen (H) = 2

From the above illustration, we can see clearly that Ca(OH)2 contains 1 calcium, 2 oxygen and 2 hydrogen.
