4. If water is added to Magnesium Nitride, ammonia gas is produced when the mixture is
heated.
Mg3N2(s) +H₂O(1)→ MgO(s) + NH3(g)
If 13.6 grams of magnesium nitride is heated with water, what volume of ammonia gas (in
mL) would be collected at 35°C and 0.937 atm of pressure?
5. If there is 256mL of propane (C3H8) is combusted at a constant pressure and temperature.
_C3H8+ O2(g) → H₂O(g) + __CO2(g)
Determine the volume of
a. Carbon dioxide produced in mL.
b. Water vapor produced in mL.
6. Circle the statement(s) that is/are true. For the false statement(s), explain why they are
false.
a. If the number of moles of a gas is doubled, the volume will double, assuming the
pressure and temperature of the gas remain constant.
b. If the temperature of a gas increases from 25°C to 50°C, the volume of the gas
would double, assuming that the pressure and the number of moles of gas remain
constant.
c. The device that measures atmospheric pressure is called a barometer.
d. If the volume of a gas decreases by one-half, then the pressure would double,
assuming that the number of moles and the temperature of the gas remain
constant.
