Was any gas released in the flask with the boiled yeast mixture?
carbon dioxide
What final volume will the gas occupy after the stopcock is open?
The answer will be the sum of the Flask A and Flask B. The Reason: A gas occupies all the space within a container.
Gas is contained in a 125mL flask The actual volume of the flask is 131.5mL What is the volume of the flask in L?
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
If a chemical reaction produces a gas how can that gas be captured in a test tube?
The flask should contain the reactants, and a bung should be put in the top of the flask. a tube should lead to a gas syringe.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
Yes
A gas held at 798 mmHg in a 400 mL flask is released into a 3 L flask What will be the new gas pressure?
106.4 mmHg
Was any gas released in the flask with the boiled yeast mixture?
carbon dioxide
A sample of nitrogen gas is stored in a 500.0ml flask at 108kpa and 10.0c the gas is transferred to a 750.0ml flask at 21.0c what is the pressure of nitrogen in the second flask?
74.8 kPa.

When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.

The flask should contain the reactants, and a bung should be put in the top of the flask. a tube should lead to a gas syringe.
What happens if the distillation flask is not securely attached to the distillation head?
If a flask is not well secured to the head, all the gas will run out of the distiller.
How many moles of gas are in a flask at 95 degrees Celsius and 748 torr if the total volume of the flask is 263mL?
88.9237 moles
A flask is weighed and has a mass of 50.0 grams Then 2.0 grams of sodium metal is added to the flask Chlorine gas is pumped into the flask This allows the sodium metal to react completely with c?
5.0 grams.
How is heat transferred away from a vacuum flask?
a vacuum flask is not 100% vacuum. it contains some particles or gas molecules which absorbs a small amount of heat.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
Yes
