Question

Examine the unbalanced equation.

CH4 + O2 → CO2 + H2O

What is the best classification for the unbalanced equation's reaction, and why?

It is a combustion reaction because carbon dioxide (CO2) is emitted as a product.
It is a synthesis reaction because O2 displaces carbon (C) and hydrogen (H).
It is a synthesis reaction because O2 combines with CH4 to create a new substance.
It is a combustion reaction because oxygen (O2) reacts with a substance

is it c?

Answer 1

No. Synthesis reactions occur when two substances combine to make one, usually more complex. Synthesis reactions are like the reverse of decomposition reactions. So b and c are not correct.

Answer 2

Its d. :)
