Limestone stalactites and stalagmites are formed in caves by the following reaction: ca2+(aq)+2hco−3(aq)→caco3(s)+co2(g) +h2o(l) if 1 mol of caco3 forms at 298 k under 1 atm pressure, the reaction performs 2.49 kj of p−v work, pushing back the atmosphere as the gaseous co2 forms. at the same time, 38.90 kj of heat is absorbed from the environment.

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
