The airbags in vehicles contain a mixture of NaN,, KNO,, and SiO,. When a car decelerates at a rapid pace, an electrical signal goes to the gas generator inside the airbag, triggering a series of three chemical reactions: 10NAN 10Na + 2KNÖ, - K,O + 5Na,O + N.(g) K,O + Na 0+ Na + Sio, - K,Sio, 10Na + 15N,(g) These reactions produce gas (N) to fill the airbag and convert sodium azide (NaN ), a highly toxic substance, to alkaline silicate (K,Sio,). The quantity of NaN, must be carefully calculated to ensure that the volume of gas is adequate to fill the airbag firmly enough to protect the passenger but not overfill and cause the bag to explode. A standard airbag needs 67 L of N, (g) to properly inflate.

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. In the first step, nitrogen and hydrogen react to form ammonia: N,(0) + 3 H,(9) → 2 NH,(9) ΔΗ-92. k In the second step, ammonia and oxygen react to form nitric acid and water: NH,(9) + 20,(9) → HNO3(g) + H,O(g) AH=-330. kJ Calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. Round your answer to the nearest kJ. ?
Much of the sulfur used in the United States comes from the hydrogen sulfide contaminant that makes "sour" natural gas smell bad. Hydrogen sulfide is separated from the other components of natural gas mostly by taking advantage of its acid-base reaction with aqueous ethanolamine: HO(CH,),NH,(aq)+H,S(g) → HO(CH,),NH,(aq)+HS (aq) Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels with 167.6 mL of ethanolamine solution and 20.9 g of hydrogen sulfide gas each. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on. vessel volume temperature A B C D 5.0 L 5.0 L 5.0 L 5.0 L 49, °C 48. °C 51. °C 50. °C X initial rate of…

It was invented in 1859 by French physician Gaston Plante and still retains application today, more than 150 years later. There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid decomposes to form sulfur trioxide and water: H₂SO4(1) SO3(9) + H₂O(1) ΔΗ=+113. In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate: Pb(s) + PbO2(s) + 2 SO3(g) â†’ 2 PbSO4(s) Î”H = -775 kJ Calculate the net change in enthalpy for the formation of one mole of lead(II) sulfate from lead, lead(IV) oxide, and sulfuric acid from these reactions.
