3, Calculate the volume of ammonia gas measured at 645 torr and 21°C that is produced by the complete reaction of calcium oxide with excess ammonium chloride to yield ammonia (NHs) gas, calcium chloride and water An automobile tire has a maximum rating of 38 psi (this is the maximum gauge pressure the tire can withstand). The tire is inflated to 11.5L and a gauge pressure of 36.0 psi. The temperature is 12°C. While driving on a very hot day, the temperature of the tire increases to 65°C and its volume expanded to 12.2 L. Does the pressure in the tire exceed the maximum rating? If the tire was not able to expand, what impact would that have had on the final pressure? Note: A tire pressure gauge reads zero when it is disconnected from the tire and exposed to atmospheric pressure. To use the gas laws, the absolute pressure (the actual pressure of the gas) must be used. Gauge pressure is corrected to the actual pressure by adding the atmospheric pressure to the gauge pressure. Assume atmospheric pressure in this problem is 14.7 psi 4.
