The chemical equation is:
2 SO2 + O2 = 2 SO3
tHe chemical equation is:SF4 + 2 H2O = SO2 + 4 HF
1,1,1
4,1,2
There are 2 oxygen on the left and one on the right. To balance the oxygen the blank will be 2. To balance out the lithium there are 4 on the right and there needs to be 4 on the right. So yes the sum of the coefficients is 7.
I believe it is already balanced. No coefficients neccessary

When the equation kmno4 plus mgs k2s plus mgmno42 is balanced, the correct set of coefficients is 2111.

See that 3 subscript on O in NaClO3 ? Hint to double the moles there. 2NaClO3 -> 2NaCl +3O2

Fe2O3 + 3CO -----> 2Fe + 3CO2
There is no single coefficient for that equation, as a coefficient is the number by which any term is multiplied. The coefficients in that equation are 5, 2, 4 and 3.
