Arigid stainless steel chamber contains 140 torr of methane, ch4, and excess oxygen, o2, at 160.0 °c. a spark is ignited inside the chamber, completely combusting the methane. what is the change in total pressure within the chamber following the reaction? assume a constant temperature throughout the process.

The variation of pressure is 0.

Explanation:

Methane combustion reaction:

The pressure change in gaseous state reactions at constant T y V is proportional to the change in the number of mol of gas in total.

As can be seen in the reaction above we have 3 moles of gas in the reactants and 3 in the products, so the variation of moles is 0. Therefore, the variation of pressure is also 0.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
