Which of the following statements about samples A and B are true? Check all that apply. View Available Hint(s) Check all that apply. After 1 hourhour, a larger percentage of undecayed atoms will be left in sample A than in sample B. After 1 hourhour, a larger number of atoms will have decayed in sample B than in sample A. After 2 hourshours, the same number of atoms will have decayed in both samples. After 2 hourshours, both samples will have the same number of undecayed atoms.

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
