Number 4 answer?
![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?

4. Draw a bomb calorimeter and label its parts. Briefly describe how
on
a bomb calorimeter works.

5. What is the difference between a coffee cup calorimeter and a
bomb calorimeter, in terms of the parameters it can measure?
6. A sample of 1.550 g of liquid hexane (C,H14) undergoes
combustion in a bomb calorimeter, and the temperature rises from
25.87°C to 38.13° Find DEn for the reaction in kJ/mol hexane. The
heat capacity of the bomb calorimeter, determined in a separate
endar
