A sample of chlorine gas starting at 687 mm Hg is placed under a pressure of 997 mm Hg and reduced to a volume of 520.7 mL. What was the initial volume, in mL, of the chlorine gas container if the process was performed at constant temperature?

What natural processes produce large quantities of co2

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

In medium-sized stars such as the sun, nuclear fusion almost always means the fusing of nuclei to form , but larger stars can produce elements as heavy as
