Question

13. A sample of N2O gas has a density of 2.95 g/L at 298 K. What must be the pressure of the gas (in mmHg)?

Answer #1

Chlorine gas reacts with fluorine gas to form chlorine
trifluoride.
Cl2(g)+3F2(g)→2ClF3(g)
A 1.90 L reaction vessel, initially at 298 K, contains chlorine gas
at a partial pressure of 337 mmHg and fluorine gas at a partial
pressure of 877 mmHg .

A sample of oxygen gas has a density of _____
g/L at a pressure of 1.23 atm and a temperature of
35

Dinitrogen oxide (N2O), laughing gas, is used by dentists as an
anesthetic. If a 20.0 L tank of laughing gas has a pressure of
2.64×103 mmHg, how many moles of N2O in the tank?

4. A Noble Gas has a density of 2.3013 g/L at 1185.6 torr and
330.0 K. What is the elemental symbol for that gas?
5. A fixed sample of gas at 45.5 K is initially at 125 mL and
684 mm Hg. What would the final pressure be in mm Hg if the volume
was expanded to a final volume of 188 mL? (The answer should have
three sig figs.)

Chlorine gas reacts with fluorine gas to form chlorine
trifluoride. Cl2(g)+3F2(g)→2ClF3(g) A 2.45 L reaction vessel,
initially at 298 K, contains chlorine gas at a partial pressure of
337 mmHg and fluorine gas at a partial pressure of 739 mmHg
.Identify the limiting reactant and determine the theoretical yield
of ClF3 in grams.

1. A sample of gas with an initial volume of 28.2 L at a
pressure of 728 mmHg and a temperature of 301 K is compressed to a
volume of 14.9 L and warmed to a temperature of 375 K. What is the
final pressure of the gas?
2. A gas sample with a volume of 5.3 L has a pressure of 725
mmHg at 24C. What is the pressure of the sample if the volume
remains at 5.3 L...

Consider the following reaction occurring at 298 K:
N2O(g)+NO2(g)⇌3NO(g)
Part A Show that the reaction is not spontaneous under standard
conditions by calculating ΔG∘rxn.
Part B If a reaction mixture contains only N2O and NO2 at
partial pressures of 1.0 atm each, the reaction will be spontaneous
until some NO forms in the mixture. What maximum partial pressure
of NO builds up before the reaction ceases to be spontaneous?
Part C Can the reaction be made more spontaneous by an...

what minimum volume of chlorine gas (at 298 K and 237 mmHg) is
required to completely react with 7.44 g of aluminum?

A sample of an unknown gas is found to have a density of
2.50 g/L at a pressure of 1.18
atm and a temperature of 38 °C. Assume ideal
behavior.
The molar mass of the unknown gas is= g/mol.

Chlorine gas reacts with fluorine gas to form chlorine
trifluoride. Cl2(g)+3F2(g)→2ClF3(g) A 2.00 L reaction vessel,
initially at 298 K, contains chlorine gas at a partial pressure of
337 mmHg and fluorine gas at a partial pressure of 784 mmHg .
Part A What is the pressure of ClF3 in the reaction vessel after
the reaction?
Part B What is the total pressure in the reaction vessel after the
reaction?
So, I've tried this problem, but I end up having...
