Question

Which reaction is balanced correctly?

C + O2 → 2CO2
CH4 + 4O2 → CO2 + 2H2O
C3H8 + 5O2 → 3CO2 + 4H2O
C6H12O6 + 3O2 → 6CO2 + 6H2O

Answer 3

Count how many times an element appears on either side of the reaction.

For example, the first is not correctly balanced because the reactant contains one atom of \(\mathrm{C}\), while the product magically consists of two. For a reaction to be balanced, the same number of atoms of each element must go in and come out.

Answer 4

So which one is?

Answer 6

To be a balanced equation, there has to be an equal amount of each element on each end of the reaction.
So the reactants, if there are 3 C atoms, and in the products there's only 2, then it's not balanced.
Understand?
