AP Writing Equation Question

For each of the following three reactions, write a balanced equation for the reaction in part (i) and answer the  question about the reaction in part (ii). In part (i), coefficients should be in terms of lowest whole numbers.  Assume that solutions are aqueous unless otherwise indicated. Represent substances in solutions as ions if the substances are extensively ionized. Omit formulas for any ions or molecules that are unchanged by the reaction. You may use the empty space at the bottom of the next page for scratch work, but only equations that are written in the answer boxes provided will be scored.

(a) Solid magnesium hydroxide is added to a solution of hydrobromic acid
            (i) Balanced equation:
 

            (ii)What volume, in mL, of 2.00 M hydrobromic acid is required to react completely with 0.10 mol of solid magnesium hydroxide?
