Question

Lawine six chemical equations describe the six reactions that you used to convert copper into compounds and ultimately reproduce the original copper sample. Consistent with the law of rvation of mass, determine if each of the given equations are balanced. Balance those that are unbalanced by including the appropriate coefficients. Reaction 1: Cu(s) + 4H*(aq) + 2NO;(aq) - Cu + (aq) + 2NO2(g) + H2O(l) Reaction 2: Cu?(aq) + OH(aq) - Cu(OH),(s) Reaction 3: Cu(OH),(s) - CuO(s) + 2H,0(1) Reaction 4: CuO(s) + H+ (aq) + HSO;(aq) + Cu²+ (aq) + SO3- (aq) + H2O(l) Reaction 5: Cu²+(aq) + Zn(s) - Cu(s) + Zn2+ (aq) Reaction 6: Zn(s) + H+(aq) → Zn2+ (aq) + H2(g) Laboratory 2 The Discovery of Chemical Change Through the Chemistry of Copper

Answer 1

Reaction O Cu(s) + 4H Foxy + 2 N0362) + cu lag) + 2NO2 (8) + 40 6) To balance this eqn, multiply How by a Balanced equus: Cu(s) + 4He may + 2 NO57ael → curent + 2NO(9) + 244060) Reaction @ Curtand + oH (94) → Cu(OH)2 (5) - To balance this equ, multiply of by 2 Balanced eqh in Cu2+ + 2014 (4) cu 6H)₂ (s) ~ Reaction @ Ca (OH), () → Cuo (5) + 24,0 (4) "Тә balana mu es” мширы Счен, ерга 4та Сло ьу 2 20u6H)₂ (5) 20uo(s) + zhor Reaction @ Cuo(s) + H tas) + HSoy (as) → Cult + Soy + yoll) - This equ is already balanced. Reaction 6: Cuztian + Zn(s) Cu(s) + Zn²+ (as) This eqn is already balanced. Reaction© : Zn(s) + H+ (2) → znate + 4, (3) To balance this equ Multiply 4t by 2 Zn(s) +aren enten + H₂(3)
