Question

1. the formula for magnesium hydroxide is

a mgoh
b mg(oh)₂
c mg₂oh
d mg₂(oh)₂

Explanation:

Magnesium has a +2 charge (\(Mg^{2+}\)), and the hydroxide ion (\(OH^-\)) has a -1 charge. To balance the charges, we need two \(OH^-\) ions for one \(Mg^{2+}\) ion. So the formula is \(Mg(OH)_2\).

Answer:

B. \(Mg(OH)_2\)
