Answer to Question #144309 in General Chemistry for Dzaky

Question

1) Sulfur dioxide, SO2, reacts with oxygen according to the following equation:

2SO2 (g) + O2 (g) → 2SO3 (g)

Calculate the volume of SO2 required to make 80 cm3 of SO3, assuming oxygen is the excess reactant.

2) Sodium hydroxide (NaOH) reacts with sulfuric acid (H2SO4) according to the following equation:

2NaOH (aq) + H2SO4 (aq) → Na2SO4 (aq) + 2H2O (l)

Calculate the volume of 2.00 mol dm-3 H2SO4 required to react with 100 cm3 of 5.00 mol dm-3 NaOH.

3) Determine the mass (in grams) of silver chloride, AgCl, that would be precipitated if an excess of AgNO3 solution is added to 55.0 cm3 of 0.200 mol dm−3 KCl solution. The balanced equation for the reaction is:

KCl (aq) + AgNO3 (aq) → AgCl (s) + KNO3 (aq)

Mr AgCl = 143.32

4) 1000 cm3 of hydrogen gas (hydrogen molecules, H2) contains x number of molecules at room temperature and pressure. Determine the number of atoms in 500 cm3 of radon gas (radon atoms) at the same temperature and pressure (assume both gases behave ideally).
