A standard size Acetylene cylinder typically contains around 7 kg of Calcium Carbide, which is used to produce Acetylene gas through a chemical reaction. The amount of Calcium Carbide used can vary depending on the size and type of the cylinder.
The reaction between calcium carbide and water produces acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2. When 1 mole of calcium carbide reacts with 2 moles of water, it produces 1 mole of acetylene and 1 mole of calcium hydroxide. The molar mass of calcium carbide is 64.1 g/mol, so the reaction would produce 26.04 grams of acetylene gas and 74.1 grams of calcium hydroxide from every 64.1 grams of calcium carbide reacted.
Sodium carbide is a chemical compound with the formula Na2C2, which is an ionic salt composed of sodium cations and carbide anions. It is a grayish-white solid that is often used in the production of acetylene gas for welding and cutting applications. Sodium carbide should be handled with care as it reacts violently with water to release acetylene gas.
Calcium carbide is a chemical compound that reacts with water to produce acetylene gas, which is combustible and is used in mining lamps. The gas also encourages fruit growth in plants such as pineapples. Calcium carbide is used in making steel, PVC, signal flares and some old-fashioned fireworks, in addition to mining. Calcium carbide is man-made. It is produced in a 2000º electric arc furnace. There is no "natural source" for the substance. You cannot go dig it up somewhere. If you could, it would be a clear or bluish crystal, rather soft, with an unpleasant odor. I would go into the science of it in more depth, but the foregoing answers the question asked and you don't need to be a chemistry major to understand it. :) +++ I'd be very surprised if miners still use acetylene lamps! They were used by miners in gas-free ground (usually metal-ore mines and underground stone quarries) many years ago. They were used by many cavers until electric lamps (usually ex-colliery) became common in the 1960s, then had a brief flurry of popularity again in the 1980s-90s when developments in caving techniques and equipment meant the electric mining lamps were no longer safe to use due to their liquid electrolytes . Now acetylene lamps are pretty well obsolete, displaced in mining and in caving by l.e.d lamps; and suppliers of calcium carbide are becoming hard to find.
Calcium carbide (CaC2) has one sigma bond and two pi bonds. The sigma bond is between the calcium atom and a carbon atom, while the two pi bonds form between the two carbon atoms.
Oxy-acetylene burners produce a very hot flame, that will melt metal.

In calcium carbide (CaC2) are 1 atom of Calcium and two of Carbon, so totally three atoms of two elements

Calcium carbide lamps have been used (historically in mines) to create light by immersing calcium carbide in water to produce acytelene gas, which burns and creates light. Although they work as lamps, the gas produced by them makes them less safe than oil lamps, and as such they were usually only used in industrial lighting rather than in homes. Electrical lighting is usually safer than either oil or carbide lamps because there is less danger of fire.
Two elements Carbon and Hydrogen in acetylene, C2H2, two atoms of each.
In a new acetylene tank that is full there is 250 psi
Brand name carbide inserts are available from many tooling suppliers. Carbide inserts are available with or without coatings to make them more durable.
Oxy-acetylene burners produce a very hot flame, that will melt metal.
Since acetylene (C2H2) has a stoichiometry of 2 moles of acetylene to produce 2 moles of CO2, three moles of acetylene would produce 3 moles of CO2. The reaction with excess oxygen ensures that all the acetylene is fully converted to CO2.
There are three covalent bonds between carbon atoms in acetylene, as acetylene has a triple bond between the two carbon atoms.
