It's kind of good at the change in temperature in degrees celsius.
00:04
So here we have hcl, n .oh, produce nacl, h2o.
00:15
I told that we have 1 molar hcl, 30 milliliters, 1 molar, neo8, 70 milliliters.
00:25
Same molarity, much less hcl, so hcl is limiting.
00:31
Nah is in excess, so any hcl would control a reaction here, so it's a limiting reactant.
00:37
So the moles of hcl equal to 1 .0 moles per liter, and 30 mill liters is 0 .030 liters.
00:47
This would give us 0 .030 moles of the h delta h here.
00:55
0 .3 moles times the enthalpy here is 57 .3 kilojoules per mole, and then times...
