Question 8 KOH Ca(NO3)2 Na2CO3 CCl4 MgBr2

Question 11 2ZnS(s) + 3O2(g) 2ZnO(s) + 2SO2(g) 2HCl(aq) + Ba(OH)2(aq) BaCl2(aq) + 2H2O(l) 2HNO3(aq) + Ca(OH)2(aq) Ca(NO3)2 + 2H2O

Question 12 Solid zinc sulfide reacts with oxygen gas to form solid zinc oxide and sulfur dioxide gas. When solid calcium hydride is added to water, aqueous calcium hydroxide and hydrogen gas are formed. Aqueous silver nitrate mixed with aqueous potassium iodide produces a precipitate of silver iodide and aqueous potassium nitrate.

Question 13 H2 + Cl2 2HCl 2Al + Fe2O3 Al2O3 + 2Fe Pb(CH3COO)2 + H2S PBS + 2CH3COOH

Question 14 LiO2 is an incorrect formula H2Cl2 is an incorrect formula MgO2 is an incorrect formula, and the equation as written is not balanced. I is an incorrect formula for iodine, and the equation is not balanced.
