thnx for all who helped

Looks right to me. However, why do you have different equation types for #6 and #7? Are they supposed to be the same?

[n.benvenuto]

one is complete combustion and the othger is incomplete combustion

Gotcha. It's good that you replied because #7 would be wrong. Also, water as a product in #6 is in gas form.

6) Methane + Oxygen Gas :   CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g) - Complete Combustion Reaction


7) Methane + Oxygen Gas   CH4 (g) + O2 (g) → C(s) + CO (s) + CO2(s) + H2O (g) - For Incomplete Combustion

oh shoot thnx man...i also have another question my friends are saying the last formula is neutralization reaction is that right?

[n.benvenuto]

hey are you sure about number 7 being

CH4 (g) + O2 (g) → C(s) + CO (s) + CO2(s) + H2O (g)

for incomplete combustion

Hello again,

Thanks for posting back because I failed to check #8 correctly.

It is not a decomposition reaction. It is a double displacement reaction, and in this case, a neutralisation reaction as well because it involves an acid reacting with a base.
