... Step 2: Balancing an equation like this is aided by making some observations. In this case, both carbon and hydrogen appear in only one place on each side of the equation. Our first steps will be to balance these two elements, because there will be no other way to adjust them. Let’s begin with carbo ...

... Note how the mol H2 unit cancels, and mol O2 is the new unit introduced. This is an example of a mole-mole calculation, when you start with moles of one substance and convert to moles of another substance by using the balanced chemical equation. The example may seem simple because the numbers are sm ...

... If you examine this equation carefully, you will notice that the number of atoms on the left side does not equal the number of atoms on the right. The equation is not balanced. In order to show that mass is conserved during a reaction, a chemical equation must be balanced. You can balance a chemical ...
