Ideal gas equation and combined gas law

(i) The first step is the catalytic oxidation of ammonia gas to nitrogen monoxide. $\ce{4NH3(g) + 5O2(g) -> 4NO(g) + 6H2O(g)}$ Determine the volume, in dm$^3$, of nitrogen monoxide produced from 20.0 g of ammonia, at STP, using section 2 of the data booklet.…

The sealed vessel was left for the reaction to proceed. Suggest two properties of the system, other than its colour, that could be measured to follow the progress of the reaction over time, and predict how each would change as the forward reaction proceeds.

A second sample of Z was converted completely into vapour at a known temperature and pressure. (i) 0.148 g of the vapour occupied 63.7 $\mathrm{cm^3}$ at 110 °C and a pressure of $1.00 \times 10^{5}$ Pa. Calculate the amount, in mol, of Z in this sample. Use…

A fixed amount of an ideal gas is kept at constant temperature while the volume of its container is decreased by 60 %. How does the pressure of the gas change? $pV = nRT$ A. Pressure decreases by 60 % B. Pressure increases by 60 % C. Pressure increases by 150…

A sample of flue gas has a volume of $2.5 \times 10^{-3}\ \mathrm{m^3}$ at 150 °C and $1.2 \times 10^5$ Pa, and contains 0.20 % $\ce{SO2}$ by volume. Using sections 1 and 2 of the data booklet, calculate the amount, in moles, of $\ce{SO2}$ present.

A rigid cylinder of fixed volume contains $N$ molecules of an ideal gas at 200 K and a pressure of 80 kPa. Half of the molecules are removed and the temperature of the remaining gas is raised to 500 K. What is the new pressure of the gas, in kPa? A. 16 B. 40…
