Question

The equations are not balanced. Which equation would have the same coefficients in the same order as 2CO2 + 3H20 C2H6O + 3O2?

FeCl3 + NH4OH Fe(OH)3 + NH4Cl
CH4 + O2 CO2 + H2O
Fe + H2SO4 Fe2(SO4)3 + H2
PCl5 + H2O HCl + H3PO4

Answer 1

ANSWER: 3rd equation

EXPLANATION:

For the first equation,

We first balanced the Nitrogen. At last we counted the no. of hydrogen and oxygen ..they were totally balanced ..so our rxn completes.

For the second quation,

We simply balanced the oxygen count.

For the third equation,

We first balanced iron then oxygen. and it comes out to have similar coefficient as the given chemical rxn in the question.

For fourth,

Balance the chlorine, then the oxygen.

NOTE: If your oxygen is balanced at last, then your chemical equation is right. If not then check your coefficients again.
