3. 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.

Please help with question 6 a-d
Mg3N2(s) +
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) + 3 CO2(g)
3ML
Determine the volume of ML
a. Carbon dioxide produced in mL.
IMLC3H83ML Co2
256 mL C3H83x256 m² CO₂ = 768 mL CO₂
b. Water vapor produced in mL.
IML C3H84m L H ₂ O
256mLC3H84x256 mL H₂0(v) = 1024mL H₂ Q(v)

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.
