Which of the following is a combustion reaction?
a 2H2O 2H2 + O2
b 2AgNO3 + H2S yields Ag2S + 2NHO3
c CH4 + 2O2 yields CO2 + 2H2O
d 2Al + N2 yields 2AlN

Tell me what you know about combustion. Like, what does it use and what does it produce?

anonymous · Answer

i know alitle about combustion engines but not much about combustion in chem

wolfe8 · Answer

Well, do you at least know that fires require oxygen?

anonymous · Answer

yes other wise it would go out

wolfe8 · Answer

And they usually give out carbon dioxide. Can you see what the answer is now?

Wolfe is right, when it comes to combustion reactions always look for Oxygen O2 in your reactants because you need plentiful of oxygen supply to make a complete combustion reaction and it will always be a separate reactant...and not in a compound for example SO2 or SO4.... because a compound can't produce enough oxygen to make a combustion reaction... i hope you caught my drift!!!! :PpPP

thanks guys i really appreciate the help

lol "combustion in engines" and "combustion in chem" is very much the same thing.. it's actually easier to understand.
