Aqueous nitric acid and ammonia can be reacted to
make ammonium nitrate. When performing the
reaction, great care must be taken to add the reactants
very slowly because the temperature of the mixture
can increase rapidly. Which of the following best
describes the reaction of nitric acid and ammonia?
a. The reaction is endothermic, and the ΔH for the
reaction is positive
b. The reaction is exothermic, and the ΔH for the
reaction is positive
c. The reaction is exothermic, and the ΔH for the
reaction is negative
d. The reaction is endothermic, and the ΔH for the
reaction is negative - .....ANSWER ...✔✔ c. The
reaction is exothermic, and the ΔH for the reaction is
negative


When cooking in the same pan and on the same burner
setting, 250 mL (about 1 cup) of water will start to boil
more quickly than 1 L (about 4 cups) of water. This is
because
a. 1 cup of water has a lower specific heat capacity than
4 cups of water
b. 1 cup of water has a higher specific heat capacity
than 4 cups of water

c. 1 cup of water has a lower heat capacity than 4 cups
of water
d. 1 cup of water has a higher heat capacity than 4 cups
of water - .....ANSWER ...✔✔ c. 1 cup of water has a
lower heat capacity than 4 cups of water


Two aqueous solutions are each at 25 °C. When the
solutions are mixed inside a perfectly insulated
calorimeter, the temperature of the mixture increases
to 48 °C. If we assume that the calorimeter absorbs no
heat from the reaction, in this experiment
a. the solution mixture is the system, and the calculated
qreaction will be negative
b. the solution mixture is the system, and the calculated
qreaction will be positive
c. the reaction is the system, and the calculated
qreaction will be negative
d. the reaction is the system, and the calculated
qreaction will be positive - .....ANSWER ...✔✔ c. the
reaction is the system, and the calculated qreaction will
be negative


How much energy must be added to 250.0 mL of water
(specific heat 4.184 J/g °C) to raise its temperature
from 20.0 °C to 100.0 °C? - .....ANSWER ...✔✔ q=mcT...
(250)(4.184)(100-20)= 83.6 kJ

50.0 g of 1.25 M HNO3 and 50.0 g of 1.50 M KOH both
have a starting temperature of 22.5 °C. When the two
solutions are added to a calorimeter, the temperature
reaches a maximum of 31.1 °C. Assuming that the final
solution has a specific heat of 4.184 J/g °C, and that no
heat escapes from or is absorbed by the calorimeter,
what is the qreaction? - .....ANSWER ...✔✔ q=msT...
(50+50)(4.1894)(31.1-22.5)= -3.598 kJ


Given the following information, what is the standard
enthalpy change for the reaction?O2(g) + 2CO(g)-->
2CO2(g)
ΔHf° CO(g) = -110.52 kJ/mol
ΔHf° O2(g) = 0 kJ/mol
ΔHf° CO2(g) = -393.51 kJ/mol - .....ANSWER ...✔✔ 2
mol (-393.51 KJ/mol) - 1 mol (0 KJ/mol) - 2 mol (-110.52
KJ/mol)= -565.98 kJ


A piece of solid gold (specific heat 0.129 J/g °C) at 227.4
°C is placed into 50.0 mL of water at 24.1 °C. The final
temperature of both the metal and water is 26.2 °C.
Assuming that all heat is transferred between the
metal and water, what is the mass of the piece of
metal? - .....ANSWER ...✔✔ 16.9 g
heat of gold=heat by H2O
