Number 4 answer?

Transcribed Image Text:3. A 400-mL solutron
in an insulated bottle. A 200-mL solution Of 0.400 M Ca(OH)2 also at
30.5°C was added to the insulated bottle. After mixing, the
temperature rose to 31.2°C. Assuming that the densities and
specific heats of the solutions are the same as that of water (Cwater
= 4.18 J g1°C 1), what is the heat evolved in the neutralization of
1.00 mol of HA?
