Question

1) Write a Total lonic Equation and a Net lonic Equation that matches each balanced chemical equation written below. Rememer to show charges on any dissociated ions. 2 Na co + Pb(OH), + Pb(CO) + NaOH (10) a) Total lonic EON: Net lonic EQN b) 3 Mg + 2 Fe(C,H,O:)) - 3 Mg(C,H,O,2 – 2 Fe Total lonic EQN: Net lonic EQN: 2) Complete each statement by filling in the correct value or term in the blank provided. (5) a) Solutions contain both and solvent in even distribution b) An 5% m/m solution of LiOH in water has 5 g of LiOH dissolved into g of H.O. c) Non-polar liquids like mineral oil are generally in water. d) Increasing the temperature of a solution will the solubility of a gas solute e) lons with a smaller charge are usually soluble in water than ions with a larger charge. A solution is prepared by dissolving 50.4 g of K.CO, into 2720 g of water. Calculate the mass/mass % K.CO, in this solution: 3) -3-
