In this reaction a scheme of a chemical reaction. the reactants are two molecules, one of which consists of a and b, and the other consists of c and d. the products are two molecules, one of which consists of a and c, and the other consists of b and d. the energy of molecules ab and cd is higher than the energy of molecules ac and bd the products have been rearranged to form reactants (a)-cd is a product
(b)- ac is a reactant
(c)- the products have less potential energy than the reactants
(d)-entropy has decreased

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

Three cards with holes are arranged in a straight line. a light is shined through the first card’s hole and travels through all three cards. what does this tell you about light rays? a) that light is reflected b) that light is refractive c) that light travels in a straight line d) that light does not travel in a straight line
