Hello there.
00:01
So in this question we're told to balance the equation and i'll start by balancing the equation and we will see if water is a product or a reactant or neither and we'll find the coefficient and we'll see or we'll find out which one is the reducing agent.
00:19
Now the equation is 3 moles of manganese plus 4 moles of nitric acid will give us 3 moles of langanese oxide.
00:45
4 moles of nitrogen oxide, nitrogen monoxide rather, and 2 moles of water.
00:57
We'll see how this balances the equation.
00:59
So if you look here, we have 12 moles of oxygen.
01:04
4 times 3 is 12.
01:06
And if you look on the other side, we have 3 times 2, which is 6 plus 4, that is 10, and plus 2 that is 12.
01:16
So the oxygen molecules are balanced.
01:22
If you look at the manganese, we have 3 here and 3 here.
01:26
So manganese is balanced.
01:28
If you look at the it's atoms, we have 4 here and 9 here, 9 here, and 2 here, 2 times 2, which is 4...
