(a) Balance the following chemical equation : `Pb(NO_(3))_(2) (s) overset(\"heat\")to PbO (s) + NO_(2) (g) +O_(2)(g)` (b) State two characteristic features of carbon which when put together give rise to a large number of carbon compounds. (c) Describe an activity to slow that acids produce ions only in aqueous solutions.
