Question

choose the product of the following reaction: mg + h₂o → __. a mg₄oh b mgbr₂ c mg(oh)₂ d mgco₃

Explanation:

Step1: Analyze the reactants

The reactants are \(Mg\) (magnesium) and \(H_2O\) (water). Magnesium reacts with water to form a hydroxide.

Step2: Check the formula of hydroxide

The formula for magnesium hydroxide is \(Mg(OH)_2\). Option a (\(Mg_4OH\)) has an incorrect formula. Option b (\(MgBr_2\)) has bromine which is not in the reactants. Option d (\(MgCO_3\)) has carbon which is not in the reactants.

Answer:

C. \(Mg(OH)_2\)
