Consider the combustion of ethylene, c2h4(g)+3o2(g)→2co2(g)+2h2o(g). if the concentration of c2h4 is decreasing at the rate of 3.8×10−2 m/s , what is the rate of change in the concentration of co2? express your answer using two significant figures. δ[co2]/δt δ [ c o 2 ] / δ t = nothing m/s

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
