Question

2)how many moles of barium sulfate are sulfate are produced from 0.1 mole of barium chloride?

b) 3 moles of BACL2 will react to produce how many moles of potassium chloride?

and so on.....

2) For the balanced equation; BaCl2 + K2SO4 → BaSO4 + 2KCI a) How many mole(s) of barium sulfate are produced from 0.1 mole of barium chloride? b) 3 moles of BaCl2 will react to produce how many moles of potassium chloride? 3) For the balanced reaction and equation: Mg3N2 + 6H20 - 3Mg(OH)2 + 2NH3 a) How many moles of H20 are needed to produce 2 moles of NH3? b) How many moles of Mg(OH)2 are produced from 125 grams of Mg3N2? 4) Zinc reacts with HCI to produce zinc chloride and hydrogen gas a) Write the balanced chemical equation for the reaction 2 Zn + Hel - ZnCl2 + H2(g) b) If 250 grams of Zinc reacts how many grams of hydrogen gas are produced?
