C4H10O(l) + O2(g) --- CO(g) + H2O(g)

Question

When I balanced it I got this
C4H10O(I) + 4O2(g) --- 4CO(g) + 5H2O

Am I correct

Answer 1

Yes; however, you need not ask if you are correct. You count atoms on the left and see if the same number is on the right. If so it balances; if not, it doesn't.
I see 4C atoms on each side.
I see 10 H atoms on each side.
I see 9 O atoms on each side.
Balanced.
