Brad and juan conducted several tests to determine the properties of silver metal. they noted that is was white, and conducted both electricity and heat. they computed the density to be 10.49 g/cm3. silver did not react with water but in nitric acid, gas was released. what evidence supports a chemical change in silver? question options: silver conducts electricity. silver reacts with nitric acid to produce a gas. silver conducted heat and as the temperature increased, became more malleable. the color of silver at room temperature is white.

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
