Acetone is used to stabilize what gas?
Acetone is used to stabilize oxygen gas. It helps to prevent the slow combustion of liquid oxygen that can occur due to trace impurities.
What state of matter is Acetylene in the cylinder under pressure?
Acetylene is different from most gasses in a tank. An acetylene tank is not hollow- it contains a porous material (think of a hard sponge) that is saturated with liquid acetone. When acetylene is pumped into the tank under pressure, it dissolves in the liquid. This is similar to how carbon dioxide dissolves in a soda (in a bottle or an) under pressure. While in the tank, it is mainly in a liquid.
How may grams of oxygen are required to burn 13.50 grams of acetylene?
To burn 1 mole of acetylene (C2H2), 3 moles of oxygen (O2) are required. The molar mass of acetylene is 26.04 g/mol and of oxygen is 32.00 g/mol. First, convert 13.50g acetylene to moles, calculate the moles of oxygen required, and then convert back to grams to find the mass of oxygen needed.
What is the acetone concentration in ppm of a solution made by mixing 23.2 mg acetone with 2.000 L water?
To calculate the concentration of acetone in ppm (parts per million), you would first convert the mass of acetone to grams (23.2 mg = 0.0232 g). Then you would divide the mass of acetone by the total mass of the solution (0.0232 g acetone / 2000 g water) and multiply by 1,000,000 to convert to ppm. Therefore, the acetone concentration would be 11.6 ppm.
How much acetone (CH3COCH3) would be needed to obtain 3.35 moles of acetone The density of acetone is 0.851 gmL.?
To calculate the amount of acetone needed, we first need to find the molar mass of acetone, which is approximately 58.08 g/mol. Then, we can use the density to convert moles to grams: 3.35 moles * 58.08 g/mol = approximately 194.788 g. Finally, we can convert grams to volume using the density: 194.788 g / 0.851 g/mL ≈ 228.91 mL of acetone would be needed.
What gas can be stabilized by acetone?
Acetylene -C2H2
Is it safe to use an acetylene tank that has not been used in about 10 years?
If there is pressure in the tank it may be possible to use it. If not I wouldn't recommend it. In the tank there are blocks of material and Acetone. These absorb the Acetylene allowing it to be charged to 300 PSI. If the Acetone (it is in liquid form) has leaked out the Acetylene could explode if the cylinder is recharged. Acetylene pressure is RED LINED at 35PSI.
What is the material that comes out when a acetylene tank is laid down too long?
That would be acetone.

Why must acetylene cylinders be stored upright?
Because the acetylene is stored dissolved in acetone. You don't want to get any liquid acetone up into the valve area where it can get into the regulator, as it can damage the regulator. If the tank does go on its side, be sure to set it upright and let it be for awhile before putting it in use.
How convert 1kg of acetone to liters?
To convert 1 kg of acetone to liters, you need to know the density of acetone. The density of acetone is around 0.791 kg per liter at room temperature, so 1 kg of acetone would be approximately 1.27 liters.
How do you convert cubic feet of acetylene to gallons?
Multiply by 7.481
How to convert Cubic feet of acetylene to pounds?
To convert cubic feet of acetylene to pounds, you need to know the density of acetylene. The density of acetylene is approximately 0.0012 pounds per cubic foot. You can then multiply the cubic feet of acetylene by the density to get the weight in pounds.
In heavy heating applications acetylene is sometimes considered unsuitable Why?
Acetylene can not be stored inside a cylinder on its own as its properties will not let it be compressed above 103.5 kPa. To solve this problem the cylinder is filled with an absorbent material such as charcoal (asbestos in olden times) and acetone is added. The absorbant material absorbes the acetone and this acetone/solvent stabilizes the gas. I can not explain why but because of this the bottles draw off rate is restricted. LPG can be compressed on its own and because of this even as some of the gas is used enough pressure can be drawn for heating unlike acetylene. Hope this helps
Why should acetylene tanks never be used while laying on there sides?
They are not hollow- they are filled with a spongy material that is saturated with liquid acetone. When the acetylene is pumped into the tank, it dissolves in the acetone, much like CO2 dissolving in a bottle of soda. If the tanks are laid on their sides, the acetone will be forced out into the hoses and torch. You will get a strange flame with a lot of excess carbon. Tanks that have been laid down should be stood up, and left in that position for at least an hour so that the acetone moves back towards the bottom of the spongy material.
Is a acetone an element or compound?
Acetone is a compound. It is a chemical compound composed of carbon, hydrogen, and oxygen atoms.
