Here we have a reaction that we have to balance in an acidic medium.
00:04
So we're going to write our two half equations where we're going to have the bromine on the top, and the one with nitrogen or the elements with nitrogen on the bottom.
00:17
So now let's balance our bromine, and then we have to add one water to the right -hand side of our bottom equation, and then one h plus to the left -hand side of the bottom equation.
00:31
Now let's take a look at charges.
00:34
We have two negative and zero on the top.
00:37
So to the right -hand side, we're going to have to add two electrons, and it looks like we have zero, zero, zero, one plus on the left -hand side.
00:48
So we're going to have to add one electron to the left -hand side.
00:52
Now let's multiply the bottom equation by two to balance those electrons.
01:02
So everything gets multiplied by two, and now let's combine it with the bromine on the top...
