Question

which is the chemical formula for magnesium hydroxide? mg(oh) 2 mgoh mgoh₂ mg₂oh

Explanation:

Magnesium hydroxide is an ionic compound. Magnesium (\(Mg\)) has a charge of \(+2\) (\(Mg^{2+}\)), and the hydroxide ion (\(OH^-\)) has a charge of \(-1\). To balance the charges, we need two hydroxide ions for one magnesium ion. The formula is written as \(Mg(OH)_2\) (the parentheses around \(OH\) indicate that the subscript \(2\) applies to the entire \(OH\) group).

Answer:

\(Mg(OH)_2\) (the first option).
