Achemist needs to create a series of standard cu2 (aq) solutions for an absorbance experiment. for the first standard, he uses a pipet to transfer 25.00 ml of a 2.96 m cu2 (aq) stock solution to a 250.0 ml volumetric flask and adds enough water to dilute to the mark. he then uses a second pipet to transfer 20.00 ml of the second solution to a 100.0 ml volumetric flask and adds enough water to dilute to the mark. calculate the concentration of the cu2 (aq) solution in the 100.0 ml volumetric flask.

Ihat will happen if i added baking soda to vinegar

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
