A 3.00 x 104 -liter storage tank was taken out of service to repair and reattach a feed line damaged in a collision with a tanker. The tank was drained and then opened several days later for a welder to enter and perform the required work. No one realized, however that a large volume of liquid nonane (C9H20) remained in a collection sump at the bottom of the tank after the draining had been completed. Nonane has a lower explosion limit of 0.80 mole% and an upper explosion limit of 2.90 mole%* (i. e., nonane-air mixtures at 1 atm can explode when exposed to a spark or flame if the nonane mole fraction is between the two given values). Use the Antoine equation to estimate the temperature at which the system would have to equilibrate in order for the gas in the tank to be at the lower explosion liimit (P=1 atm).
How many liters of liquid nonane would be required to evaporate in order to meet the lower explosion limit?
Use the Antoine equation to estimate the temperature at which the system would have to equilibrate in order for the nonane in the tank gas to reach a mole fraction of 0.012?

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point
