Question

HELP PLEASE!
What are the products of the following combustion reaction?
2C2H2(g)+5O2(g)->
A) C4H2(g)+H2O2(g)+4O2(g)
B) 4C(s)+2H2O(g)+4O2(g)
C) 4CO2(g)+2H2O(g)
D) 4CO2(g)+H2O(g)+2O2(g)

Answer 1

in combustion reactions water and carbon dioxide are always produced.

btw, post chemistry q's in the chemistry section.

Answer 2

water and carbon dioxide = CO2+H2O= H2CO3

Answer 3

yeah, but it's not necessary to write "= carbonic acid"

that's not part of the reaction

Answer 4

I'm so confused

Answer 5

a combustion reaction looks like this:

hydrocarbon + oxygen gas -> carbon dioxide + water

Answer 6

So C?
