To determine how much heat is produced for this neutralization reaction, we need to know what the balanced chemical reaction is and the delta h for the process.
00:11
Hcl reacts with sodium hydroxide to produce nacl and water.
00:19
They didn't give us the delta h, but we can look up delta h of neutralization.
00:24
Delta h standard is equal to negative 57 .9 kilojoules per mole of either acid or base, dependent upon what the limiting reactant is.
00:41
So to determine the amount of heat released, we can calculate the amount of heat that would be released if each of these reacted completely.
00:51
We have 100 milliliters of hcl, that is 0 .100 liters.
00:57
If we multiply that by its concentration of 0 .250 molar, that's 0 .250 moles per liter, we'll get the moles of hcl and one mole hcl, when it reacts, releases 57 .9 kilojoules of energy...
