Best Answer

First you need to work out the balanced equation.

2C2H2 + 5O2 -----> 4CO2 + 2H2O

From this we see that 2 moles of acetylene produces 4 moles of carbon dioxide. 1 mole of carbon dioxide is 12 + 16 + 16 = 44g (adding the mass numbers of the component elements).

If 1 mole = 44g then 4 mole = 176g

What is the name of the gas that is filled in cylinders?

Many gases are filled in cylinders and include nitrogen, Carbon Dioxide, Helium, Hydrogen, Argon, Acetylene etc. Small cylinders that are extremely portable include butane etc.


What has the greatest compressibility?

Hydrogen has a density of 0.08988 g/L. After that is helium (0.1786 g/L) .Liquefied GasesLiquefied gases are gases which can become liquids at normal temperatures when they are inside cylinders under pressure. They exist inside the cylinder in a liquid-vapour balance or equilibrium. Initially the cylinder is almost full of liquid, and gas fills the space above the liquid. As gas is removed from the cylinder, enough liquid evaporates to replace it, keeping the pressure in the cylinder constant. Anhydrous ammonia, chlorine, propane, nitrous oxide and carbon dioxide are examples of liquefied gases. Non-Liquefied GasesNon-liquefied gases are also known as compressed, pressurized or permanent gases. These gases do not become liquid when they are compressed at normal temperatures, even at very high pressures. Common examples of these are oxygen, nitrogen, helium and argon. Dissolved GasesAcetylene is the only common dissolved gas. Acetylene is chemically very unstable. Even at atmospheric pressure, acetylene gas can explode. Nevertheless, acetylene is routinely stored and used safely in cylinders at high pressures (up to 250 psig at 21°C). This is possible because acetylene cylinders are fully packed with an inert, porous filler. The filler is saturated with acetone or other suitable solvent. When acetylene gas is added to the cylinder, the gas dissolves in the acetone. Acetylene in solution is stable.

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 can you prepare ethanol from acetylene?

Full combustion of methane yields only carbon dioxide and water. However, acetylene is one of the products of the partial oxidation (i.e. incomplete combustion) of methane. According to [1], "Acetylene may be produced from methane in any process which raises the methane to a high temperature for a very short period followed by rapid cooling. [....] The process was studied at temperatures of 1000°C to 1300°C and reaction times of .01 to .03 seconds." Source: [1] http://circle.ubc.ca/handle/2429/41033


How many molecules of carbon dioxide are produced when 133 molecules of acetylene (HCCH) to react in excess oxygen produce carbon dioxide water?

Here we're going to assume none of the acetylene gets a chance to escape into the atmosphere. Since it's lighter than air, we'll have to...I don't know, react it in a jar or something. We know the reaction we're going for is: C2H2 + n(O2) (meaning we have more oxygen than we could ever use) -> 2CO2 + H2O + n(O2) Therefore, to get the number of molecules of CO2 from this reaction, just double the molecules of acetylene and you're golden. How acetylene ACTUALLY burns is a little different. Three reactions occur simultaneously: C2H2 + O2 -> 2CO + H2 2CO + O -> 2CO2 2H2 + O2 -> 2H2O It does this because acetylene is so energetic it can't wait to split two molecules of oxygen apart before it reacts. But at the end of it, you still get two CO2 molecules for every acetylene molecule.

Why does acetylene set of sulfur dioxide sensors?

SO2 sensors have a cross sensitivity of approximately 150% to acetylene gas meaning if there are 45ppm acetylene gas in the air then your SO2 monitor will read approx 60ppm....one way to tell them apart is to have a second monitor to like a multi-gas or four-gas monitor or something that measures LEL's (lower explosive limit) values of flammable gases....If your showing 0 LEL's while getting a value for SO2 .... than it IS SO2 and NOT Acetylene. Where i work we have constant SO2 leak issues and the company i work for is always trying to blame it on acetylene to prevent WCB cases for low exposures...so I always bring a LEL measuring device with me to do SO2 gas sweeps and to eliminate the possibility of acetylene.....Also be aware that CO (Carbon Monoxide) will have a similar effect on H2S monitors....Hope this helps and be safe out there!


What is the chemical equation for acetylene gas C2H2 burns in a welding torch with oxygen to form carbon dioxide gas and water vapor?

2C2H2(g) + 5O2(g) = 2H2O(g) + 4CO2(g) or, 2 Acetylene molecules + 5 Oxygen molecules = 2 water molecules + 4 Carbon dioxide molecules (+ energy)
