Question

How do you balance #C_6H_6 + H_2 -> C_6H_12#?

Peyton Adams · Accepted Answer

undefined To balance the equation C6H6 + H2 -> C6H12, you need to put a coefficient of 3 in front of the H2, giving you the balanced equation:

C6H6 + 3H2 -> C6H12

#C_6H_6 + 3H_2 -> C_6H_12#

Most of the time, solving equations involves more of an algorithm than a precise process; sometimes, you have to try a few different approaches until you find one that works.

First of all, it is useful to know the mass of the components on each side as well as the amount of carbon and hydrogen that are reacted with and formed afterwards.

On the left we have #6# carbon and #8# hydrogen, while on the right we have #6# carbon and #12# hydrogen. You want all the numbers for each element to be the same. Carbon is already there, six on both sides, it's just hydrogen that you have to sort out.

You need four more hydrogen to make #8# into #12#, preferably without changing the number of carbons, though sometimes this is unavoidable and you have to do a few extra steps to sort this new problem, or try something else.

Luckily you have some elemental hydrogen, #H_2#, which means you can change the number of hydrogen without affecting anything else. When balancing equations, elemental molecules are your friend.

To get #4# more hydrogen atoms, you need #2# more #H_2# molecules, which makes #3# in total, rendering the whole equation

#C_6H_6 + 3H_2 -> C_6H_12#

There is #6# carbon and #12# hydrogen on the left, and #6# carbon and #12# hydrogen on the right. The equation is balanced.

undefined To balance the chemical equation C6H6 + H2 -> C6H12, we follow these steps:

1. Count the number of carbon atoms on both sides of the equation. We have 6 carbon atoms on each side.

2. Count the number of hydrogen atoms on both sides of the equation. We have 6 hydrogen atoms on the left side and 12 hydrogen atoms on the right side.

3. Count the number of hydrogen atoms in the H2 molecule. There are 2 hydrogen atoms in each H2 molecule.

4. To balance the hydrogen atoms, we need to have the same number on both sides of the equation. Since we have 6 hydrogen atoms on the left side and 12 hydrogen atoms on the right side, we need to multiply the H2 molecule on the left side by 6 to get 12 hydrogen atoms. The balanced equation becomes:

C6H6 + 6H2 -> C6H12

Now, the number of hydrogen atoms is balanced.

5. Finally, double-check to make sure the number of carbon atoms is still the same on both sides of the equation. In our balanced equation, we have 6 carbon atoms on each side, so it is balanced.

That's it! The balanced equation is C6H6 + 6H2 -> C6H12.
