Classify each of the following chemical reactions: a) 3 Sn(s) + 2 P(s) Sn3P2(s) [Select] b) 2 HCIO4(aq) + Ba(OH)2(s) — Ba(CIO4)2(s) + 2 H2O(1) [Select] c) Cu(s) + 2 AgCzH302(aq) – Cu(C2H302)2(aq) + 2 Ag(s) Select] d) 2 LICIO3(s) - 2 LICI(s) + 302(9) [ Select e) Pb(NO3)2(aq) + 2 LiCl(aq) - PbCl2(s) + 2 LINO3(aq) Select

Answer 1

Classify each of the following chemical reactions: a) 3 Sn(s) + 2 P(s) - Sn3Pz(s) COMBINATION, as two elements combine to form a compound. b) 2 HCIO4(aq) + Ba(OH)2(s) – Ba(CIÓ.)z(s) + 2 H2O(1 NEUTRALISATION, Bal OH)2 is a base and HCIO4 is an acid c) Cu(s) + 2 AgC2H2O2(aq) -- Cu(C2H30 3)2(aq) + 2 Ag(s) Single replacement, as Cureplaced Ag from its salt. d) 2 LICIO3(s) – 2 LICI(s) + 3024) Decomposition, as one compound changed into two compounds. e) Pb(NO3)2(aq) + 2 LiCilag) - PbC1,(s) + 2 LINO3(aq) double displacement, as Pb and Li exchanged their anions.
