ethyne from calcium carbide

Calcium carbide CaC2 reacts with water to form ethyne

First let's start with terminology C2H2 is not Ethylene it is Acetylene now for calculation: water mol mass is 18 C2H2 mol mass is 30 CaC2(s) + 2H2O(l) → C2H2(g) + Ca(OH) 2(s) 2 mols of water will yield one mol of Acetylene hence 36g water g

Calcium carbide

Carbide lamps or acetylene gas lamps are simple lamps that produce and burn acetylene (C 2 H 2 ) which is created by the reaction of calcium carbide (CaC 2 ) with water (H 2 O) It was prepared by the hydrolysis of calcium carbide a reaction discovered by Friedrich Whler in 1862 and still familiar to students: Arc furnaces were also used to prepare calcium carbide for use in carbide lamps

Acetylene

Acetylene may be generated by the chemical reaction between calcium carbide and water This reaction produces a considerable amount of heat which must be removed to prevent the acetylene gas from exploding There are several variations of this process in which either calcium carbide is added to water or water is added to calcium carbide Both

when water is added to solid calcium carbide CaC2

Calcium carbide CaC2 can be produced in an electric furnace by strongly heating calcium oxide (lime) with carbon The unbalanced equation is CaO(s) + C(s) CaC2(s) + CO(g) Calcium carbide is useful because it reacts readily with water to form the asked by Mariana on February 5 2011 chemistry when water is added to solid calcium carbide CaC2 acetylene gas C2H2 and calcium hydroxide

Organic Chemistry/Alkynes

From Calcium carbide Calcium carbide is the compound CaC 2 which consists of calcium ions (Ca 2+) and acetylide ions C 2 2- It is synthesized from lime and coke in the following reaction: CaO + 3C → CaC 2 + CO This reaction is very endothermic and requires a temperature of 2000 o C For this reason it is produced in an electrical arc
