Homework Answers
we know,
heat = m * s* (Tf - Ti)
Neutralization reactions are exothermic reaction that means heat is released during reaction.
As heat is produced and so temperature of the mixture increases from initial temperature.
thus
final temperature should be higher than initial temperature.
so
we should have final temperature above 21.48 oC.
Hence
Data is not correct.
