Cars run on gasoline, where octane (c8h18) is the principle component. this combustion reaction is responsible for generating enough energy to move a vehicle, or do other work.

how much co2 and h2o (in grams) are produced in the combustion of 1.24 gallons of octane? (density = 0.703 g/ml)

conversion, there are 4 quarts in a gallon. beyond that, check out your equation sheet for other useful conversion factors!

Explanation:

The combustion reaction of Octane is:

To calculate the mass of CO₂ and H₂O produced, we need to know the mass of octane combusted.

We calculate the mass of Octane from the given volume and density, using the following conversion factors:

Now we convert 1.24 gallons to mL:

We calculate the mass of Octane:

Now we use the stoichiometric ratios and molecular weights to calculate the mass of CO₂ and H₂O:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
