Automakers are always investigating alternative reactions for the generation of gas to inflate air bags, in part because the sodium produced in the decomposition of NaN3 presents safety concerns. One system that has been considered is the oxidation of graphite by strontium nitrate, Sr(NO3)2, as shown in the equation below. 5 C(s) + 2 Sr(NO3)2 (s)→ 2 SrO(s) + 2 N₂(g) + 5 CO₂ (g) Suppose that a system is being designed using this reaction, and the goal is to generate enough gas to inflate a bag to 63 L and 1.4 atm at 23°C. What is the minimum mass of graphite that should be used in the design of this system? g C(s)

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Chloramine is a toxic gas that can form in swimming pools by the reaction of hypochlorous acid, used to sanitize pool water, with ammonia, a component of sweat and urine. Chloramine gas, NH₂Cl(g), is the cause of the identifiable 'pool smell'. The balanced chemical equation for the reaction of hypochlorous acid and ammonia is: HOCl(aq) + NH₃(aq) → NH₂Cl(g) + H₂O(l) A swimming pool holding 9.50 × 10⁴ gallons of water. 1.00 gallons HOCl sanitizer is enough to sanitize 1.00 × 10⁴ gallons of pool water. The sanitizer has a concentration of 12.00 mg/L of Cl atoms. Determine the moles of chloramine are produced if ammonia is in excess. (1 gal = 3.785 L)
