Classify each chemical equation as a combination/synthesis, decomposition, single replacement, double replacement, or combustion

A. Pb (s) + Hg2SO4 (s) - - - > PbSO4 (s) + 2 Hg (I)

B. NaCI (aq) + AgNO3 (aq) - - - >AgCI (s) + NaNO3 (aq)

C. 2H20 (I) - - - >2H2 (g) + 02 (g)

We classify each of the reaction as follows:

A. Pb (s) + Hg2SO4 (s) - - - > PbSO4 (s) + 2 Hg (I)

Single replacement reaction

B. NaCI (aq) + AgNO3 (aq) - - - >AgCI (s) + NaNO3 (aq)

Double replacement reaction

C. 2H20 (I) - - - >2H2 (g) + 02 (g)

Decomposition reaction

Hope this answers the question. Have a nice day.
