Question
Classify each of the unbalanced chemical reactions as one possible types by matching the classification to the correct reaction.
Co(NO3)2(aq) + H2S (g) = CoS (s) + HNO3(aq)
Fe (s) + Cd(NO3)2(aq) = Fe(NO3)2 (aq) + Cd (s)
Fe2(CO3)3(s) = Fe2O3(s) + CO2(g)
Sn (s) + P (s) = Sn3P2(s)
A.
combination
B.
decomposition
C.
double replacement
D.
neutralization
E.
single replacement
Co(NO3)2(aq) + H2S (g) = CoS (s) + HNO3(aq)
Fe (s) + Cd(NO3)2(aq) = Fe(NO3)2 (aq) + Cd (s)
Fe2(CO3)3(s) = Fe2O3(s) + CO2(g)
.Sn (s) + P (s) = Sn3P2(s)
Explanation / Answer
1. Co(NO3)2 (aq) + H2S (g) = CoS (s) + HNO3 (aq) - Double replacement
2. Fe(s) + Cd(NO3 )2 (aq) = Fe(NO3)2 (aq) + Cd (s) - Neutralisation
3. Fe2(CO3)3 (s) = Fe2O3 (s) + CO2 (g) - Decomposition
4. Sn (s) + P (s) = Sn3P2 (s) - Combination
