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:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
