Question

I am having issues coming up with the definitions of these. Can you please explain why they are the answers?

My current answers are bolded/in parenthesis

1. (endothermic process) NH4Cl+57kJ?NH3+HCl

2. When 1 gram of water is heated, its temperature rises from 20 oC to 21 oC.The heat absorbed by water is equal to the (heat capacity?)

3. (?E?) When the internal energy of the ideal gas is increased, heat is absorbed by the system when it is compressed.

4. (First Law of thermodynamics?) Energy is neither created nor destroyed.

5. (Molarity?) molL

6. (?H?) is the heat of reaction at constant pressure.

7. (Heat capacity?) J/g oC

8. (Calorimeter?) a vessel used to measure heat transfer

9. (Perfect calorimeter) heat transfer to the surroundings = 0

10. (Specific heat) J/oC

11. (Exothermic process) ?H=?

12. (?H) Heat absorbed is equal to Heat released.

13. (Exothermic process) NaOH+NH4Cl?NaCl+NH3+H2O+3kJ

Said 5/13 are incorrect.

Here are the possible answers. Can be used more than once.

exothermic process

perfect calorimeter

specific heat

heat capacity

molarity

First Law of thermodynamics

endothermic process

calorimeter

the answer for 5)

Molarity: It is the number of moles of solute dissolved in1L solution. In short form, you can write it as

molarity = moles of solute/Volume of solution (L)

moles = mass of solute(g)/molar mass of solute

answer 13: endothermic reaction

+3KJ means 3KJ energy is required for this reaction to convert reactant to products
