A 11.5L sample of nitrogen at 20oC and 0.5 atm is placed in an oven. If the ending pressure and volume were 2.5 atm and 25L respectively, what was the final temperature?
How many moles of CO2 could fit in a 575mL bag at 15oC and 745 mmHg?
How many molecules of Ne could fit in a 5.00 L bottle at 32oC and 650mmHg?
What volume would be occupied by 44.0 g of of CO2 at 0oC and 760mmHg?
Determine the density of 1 mol of argon gas at 705 mmHg and 333 K.
Why does the temperature of the sample remain constant between point X and point Y?
because the sample is transitioning from a gaseous state to a solid state
because the sample is transitioning from a gaseous state to a liquid state
because the sample is transitioning from a solid state to a gaseous state
because the sample is transitioning from a liquid state to a solid state
The phases of a substance under various pressure and temperature combinations are shown on the phase diagram above. What occurs if the pressure of the substance at point F remains constant, and the
temperature increases to point G?
It will transition from a solid state to a liquid state.
It will transition from a liquid state to a solid state.
It will transition from a solid state to a gaseous state.
It will transition from a gaseous state to a solid state.
The potential energy diagram of a chemical reaction is shown above. Which best describes the energy in the chemical reaction?
Heat energy was released.
Energy was lowered by a catalyst.
8 J of energy were required to start the reaction.
10 J of energy were required to start the reaction.
