This is a classic, you know, adding up delta h to formation to find the delta h reaction.
00:06
But instead of looking for the delta h to a reaction, we're given that instead of we're looking for the delta h of this one product.
00:14
And actually, that's a pretty common thing that a chemist would actually do.
00:17
It's easy for a chemist to do a reaction and see what the change in energy is or the amount of heat that's released.
00:24
But they might be doing that to figure out what the delta h of formation is of one of the.
00:30
Reactants or products here.
00:31
And so remember, we always use this phrase describe what we, the calculations we do.
00:35
We do products minus reactants.
00:39
And so i've written in red here, all of the delta h to formation is the one we're looking for.
00:46
And so we're going to take products minus reactants.
00:48
We will.

We would start with n2, but it's zero, so we ignore it...
