Finish and balance the following acid-base equations. (Assume that these reactions go to completion. Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)
(a) A solution of HMnO4 is added to solid Al(OH)3.
(b) Solid Al2O3 is treated with a solution of HClO3.
(c) A solution of H3AsO4 reacts with solid NaOH.
Finish and balance the equations for the following acid-base neutralization reactions. Write complete ionic equations. In some cases, there may be more than one correct answer, depending on the amounts of reactants used. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.)
(a) SO3(g) + H2O(l) → (assume an excess of water and that the product dissolves)
(b) BaO(s) + H2SO4(aq) → (assume that the resulting salt precipitates)
(c) Ni(OH)2(s) + HClO4(aq) → (assume that the resulting salt is soluble)
