Mg(s) + 2H2O(l) = Mg(OH)2(aq) + H2(g) What is the concentration of hydroxide ions in the solution formed when 4.00g of Mg(s) react with sufficient water to form 200. mL of solution?

How many L NaOH of a 0.075 M NaOH solution is needed to completely neutralize 100.0 mL of a 0.250 M H₂SO solution according to the balanced chemical reaction: 4 2 NaOH(aq) + H₂SO (aq) → 2 H₂O(l) + Na₂SO (aq)

The amount of nitrogen in an organic substance can be determined by an analytical method called the Kjeldahl method, in which all the nitrogen in the organic substance is converted to ammonia. The ammonia, which is a weak base, can be neutralized with hydrochloric acid, as described by the equation NH3(aq) + HCl(aq) ->> NH₂Cl(aq) If 6.0 mL of 0.150 M HCl(aq) is needed to neutralize all the NH3(g) from a 2.25 g sample of organic material, calculate the mass percentage of nitrogen in the sample.
