Question

Setarakan reaksi reaksi berikut dengan substitusi dan eliminasi .A. Al2(SO4)3(aq) + BaCl2(aq)->BaSO4(s)+AlCl3(aq)
B. Cu(s) +H2SO4(aq)->CuSO4(aq)+H2O(l)+SO2(g)
C. Al(OH)3(s) + HNO3(aq)->Al(NO3)3(aq)+H2O(l)

Answer 1

Al2(SO4)3(aq) + 3 BaCl2(aq) => 3 BaSO4(s) + 2 AlCl3(aq)

Cu(s) + 2 H2SO4(aq) => CuSO4(aq) + 2 H2O(l) + SO2(g)

Al(OH)3(s) + 3 HNO3(aq) => Al(NO3)3(aq) + 3 H2O(l)
