thq but i get confused in using trial and error method.. it takes too much time for me to do just 1 question .. do you know any other method which is more accurate?
like this:
1)H2SO4 + Al(OH)3 --> Al2(SO4)3 + H2O
2)Pb2+ + Cl- --> PbCl2
and word equation like this
ethane(C2H6) + Oxygen --> Carbon dioxide + Water vapour
Thq.
