WebAs water dripped down, often from an elegant brass container, the unusually structured calcium carbide, which has a triple bond between its pair of carbon atoms, reacts to produce calcium hydroxide and acetylene. More properly ethyne, acetylene retains that unusual triple bond in its C 2 H 2 structure, and is highly flammable. Web(c) One of the ways that ethyne gas can be produced is via the reaction of calcium carbide, CaC2, with water, producing solid calcium hydroxide as a by-product. (i) Using the following information and relevant data from the Data Booklet, construct an energy cycle to calculate the lattice energy of solid calcium hydroxide.
