The complete combustion of octane, c8h18, the main component of gasoline, proceeds as follows: 2c8h18 (l) + 25 o2(g) --> 16 co2(g) + 18 h2o (g)
a. how many moles of 02 are needed to burn 1.50 mol of c8h18?
b. how many grams of 02 are needed to burn 10.0 g of c8h18?
c. octane has a density of 0.692 g/ml at 20 degrees celsius. how many grams of 02 are required to burn 15.0 gal of c8h18 (the capacity of an average file tank)?

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol
