Question

Dentify the following chemical reactions as decomposition, combination/synthesis, single-displacement, double-replacement, or combustion.

(a) AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq)
(b) C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l)
(c) Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s)
(d) Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s)
(e) SrO(s) + SO2(g) → SrSO3(s)

Answer 1

The chemical reactions are classified as double-replacement, combustion, single-displacement, single-displacement, and combination/synthesis reactions.

Step-by-step explanation:

Chemical reactions involve the transformation of substances into new ones with distinct properties. Reactants undergo change to produce products through the breaking and forming of chemical bonds. Equations symbolize these transformations, emphasizing conservation of mass and energy. The reactions can be categorised as -

(a) AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) - Double-replacement reaction
(b) C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l) - Combustion reaction
(c) Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s) - Single-displacement reaction
(d) Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s) - Single-displacement reaction
(e) SrO(s) + SO2(g) → SrSO3(s) - Combination/synthesis reaction
