Kaiden Bryant · Answer 1

Mg (OH) ^2 because it is followed by (s), meaning solid. Mg (OH) 2 is precipitated from the solution.

The answer is D.

Josh Hodges · Answer 2

The correct answer is D. Mg (OH) ₂. Precipitation reactions form products of which one is a precipitate denoted as (s) in the state symbols which means that it is in solid form, while the other products and reactants remain in solution or liquid form. In this reaction there is only one solid product and that is magnesium Hydroxide.
