Answer all questions please
A solution of Ba(OH)_2(aq) is titrated with a solution of HCl(aq). a. Write the balanced equation for this reaction. b. What volume in mL of 0.2501M HCl is needed to neutralize 50.00 mL of 0.1055 M Ba(OH)_2 ? What mass NaOH is needed to precipitate the Cd^2+ ions from 25.0 ml of 0.450 M Cd(NO_3)_2 solution? 2 NaOH (aq) + Cd(NO_3)_2 (aq) rightarrow Cd(OH)_2(S) + 2 NaNO_3(aq) Consider the following reaction: 2 CH_3 OH(g) rightarrow 2CH_4(g) + O_2(g) Delta H = +252.8 kJ a. Is this reaction endothermic or exothermic? _________ b. Calculate the amount of heat transferred when 48.0 g of CH_3 OH(g) is decomposed by reaction at constant pressure.
