Which of the following chemical equations depicts a balanced ionic equation?

Option C. 2OH¯ + Ca²⁺ —> Ca(OH)2

Explanation:

OH¯ + Ca²⁺ —> Ca(OH)2

The above equation can be balance as follow:

OH¯ + Ca²⁺ —> Ca(OH)2

There are 2 atoms of OH on the right side and 1 atom on the left side. It can be balance by putting 2 in front of OH¯ as shown below:

2OH¯ + Ca²⁺ —> Ca(OH)2

Next, we shall balanced the charge on both side. This can be obtained as follow:

Total charge on the left side = –2 + 2

Total charge on the left side = 0

Total charge on the right side = 0

Thus, the charge on both side are equal. Hence, the balance ionic equation is:

2OH¯ + Ca²⁺ —> Ca(OH)2

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
