(USCG, 1999) Health Hazard. Still have questions? [2] d.i. [1] d.ii. When water is added to solid calcium carbide, CaC2, the produces are acetylene gas, C2H2, and aqueous calcium hydroxide.a. Calcium carbide reacts with water to form ethyne and calcium hydroxide. Write the balanced chemical equation for this reaction.b. Impure calcium carbide, such as technical grade type, also has other calcium compounds, like calcium sulfide, calcium nitride, calcium phosphide, which in contact with water it will also produce phosphine, ammonia or hydrogen sulfide. Cal­ci­um car­bide is not volatile and not sol­u­ble in any known sol­vent, and re­acts with wa­ter to yield acety­lene gas and cal­ci­um hy­drox­ide. CaC2(s) + 2H2O(l) = C2H2 (acetylene gas) + Ca(OH)2(s) rihu27 rihu27 Answer;c2d2 is formed. (b) When solid potassium chlorate is heated, it decomposes to form solid potassium chloride and oxygen gas. 10.41 Write the balanced molecular, complete ionic, and net ionic equations for the following: Solid calcium carbide (CaC2) reacts with water to form gaseous acetylene (C2H2) … l type='a'> Write the balanced equation for the reaction that is (occurring.
