What else can I help you with?
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.
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?
When the water level is higher inside than outside the flask, the gas pressure in the flask is lower than the atmospheric pressure. This is because the weight of the column of water inside the flask creates an additional pressure on the gas inside, reducing its pressure relative to the atmospheric pressure outside.
What is the total pressure in the flask?
The total pressure in a flask is the sum of the partial pressures of all the gases present in the flask. It can be calculated using the ideal gas law equation, PV = nRT, where P is the total pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.
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

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?
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.

The answer will be the sum of the Flask A and Flask B. The Reason: A gas occupies all the space within a container.
Why should the flask be covered not stoppered?
Covering the flask instead of stoppering it allows for any gas produced during the reaction to escape, preventing pressure build-up that could lead to the flask exploding. Stoppering the flask could trap the gas and result in a dangerous situation.

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?
To find the pressure of the nitrogen gas in the second flask, you can use the combined gas law equation: P1V1/T1 = P2V2/T2, where P1, V1, and T1 are the initial pressure, volume, and temperature, and P2, V2, and T2 are the final pressure, volume, and temperature. Plug in the given values to find the final pressure of nitrogen in the second flask.

Is the volume occupied by the gas in the flask approxmately the same greater or less than before it was heated?
Assuming the flask is sealed - the volume remains the same but the pressure increases
What is true about the pressure of the gas in the flask?
In a Gas Flask, there are several components which make pressure possible. External source of Heat ( ie motor heat, direct sunlight, outside tempature), movement and internal friction of the gas particles can cause pressure. Although,Gasoline is a low pressure gas and will not exceed 200 lbs of pressure in a container, it is best stored out of direct heat. The GAS FLASK has a natural pressure relief system built in (as required by D.O.T.). The Gas Flask is made of billett aluminum and manufacutured in the USA. The Gas Flask (Service Mark and TradeMark of Texas Connexion, Amarillo, TX) is the only DOT approved gas container for your motorcycle that looks as good as your bike does. Able to carry from 1/4 gallon to 1/2 gallon of spare gas in your saddle bag, you will be the envy of your friends. When some one runs out of gas... Just do as our slogan says...

Why is it important that the flask be sealed for this experiment even after the flask is returned to an upright position?
Keeping the flask sealed after it is returned to an upright position prevents any air or gas from escaping, ensuring that the pressure inside the flask remains constant. This helps to maintain the accuracy of the experiment's results by keeping the conditions consistent.
Flask A contains 2 liters of ch4 g and flask B contains 2 liters of o2 g each gas sample has the same?
The gas particles in both flask A and B will have the same average kinetic energy at the same temperature. This is because temperature is a measure of the average kinetic energy of the gas particles, and since they are at the same temperature, their average kinetic energies will be equal.
