This question needs to be answered in full and submitted in the Part 2 assignment link. Please note all the relevant variables, i.e. mass, volume, pressure and temperature.At elevated temperatures, sodium chlorate decomposes into sodium chloride and oxygen gas. 2 NaCℓO3 (s) → 2 NaCℓ (s) + 3 O2 (g) A 0.6625 g sample of impure sodium chlorate was heated until the production of oxygen ceased. The oxygen, collected over water, occupied 65.4 mL at 22.0⁰C and 743 torr.(At 22.0⁰C the vapour pressure of water is 19.8 torr) The mass percent of NaCℓO3 (106.4407 g/mol) in the original sample, i.e. percentage purity, in %, is

Sulfur dioxide and oxygen react to form sulfur trioxide, like this: 2 SO₂(g) + O₂(g) → 2 SO 3(g) The reaction is exothermic. Suppose a mixture of SO₂, O₂ and SO3 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation The temperature is lowered. change in composition The pressure of SO₂ will The temperature is raised.

Cloudy Solving for a reactant in solution One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution like this: FeCl₂(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Fe(NO3),(aq) The chemist adds 29.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 3.2 mg of silver chloride. Calculate the concentration of iron (II) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits. 4 e mg L Explanation Check X 99+ Ⓒ2022 McGraw Hill LLC.
