Reaction between hydrogen selenide and tin
If the temperature and pressure are unchanged, the gas volume when the decomposition is over is the same as it was to begin with.

balanced equation and ideal gas law
What will be the volume of the gas sample if the pressure increases to 810 mm and the temperature increases to 30oC?
4. A gas sample has an original volume of 550 ml when collected at 740 mm and 30oC.

One Mole of any gas occupies 22.4 L at STP
Change this volume 920/7 L to Normal Pressure and Temperature (NTP) using gas equation. Let volume at NTP be V'.
{ (PV)/T = (P'V')/T' where P' and T' are normal pressure and temperature and V' is corresponding volume.

Chemistry Questions: Gases and Gas Reactions
Clearly, 8 liters of H2S is 4 times the original amount in the balanced chemical equation. Therefore, we only need 4 times the amount of O2 gas. Since we have 3 liters in the chemical equation, we only need 12 liters (3 liters x 4) of O2 gas.

Pressure of Gas
16038 Pressure of Gas Temperature Equations A sample of gas occupies 135 mL at 22.5 C; the pressure is 165 mm Hg. What is the pressure of the gas sample when it is placed in a 252-mL flask at a temperature of 0.0 C?

the relationships between temperature, pressure and volume
You can understand this using the chemical equation pV=nRT, where p is pressure, V is volume, and T is temperature.

Gibbs free energy and chemical potential
Second relation shows that the pressure variation of chemical potential depends on molar entropy. If molar volume increases, chemical potential also increases as pressure increases.

Physics: Calculate the PV work that is done ON the system
Now let us say a gas changes its volume ( it may be expansion or compression,) at a constant pressure, then the work done (by the gas OR on the gas ) can be given by
W = PV.

Combined Gas Law and Mixtures of Gases
If the temperature changes to 73 , and there is no change of pressure or amount of gas, what is the new volume, , of the gas?
Express the volume numerically in liters.
