Calcium carbide will immediately have reaction upon coming across with water, generating acetylene and calcium hydroxide, which is the approach of industrial preparation of acetylene (carbide method), the reaction equation is: CaC2 + 2H2O = C2H2 + Ca (OH) 2. ...
To write the symbolic representation for the word equation "Calcium + Water → Calcium Hydroxide" and balance it, follow these steps:Step 1: Write the Symbolic Representation - Calcium is represented by the symbol Ca
a malleable silvery-white metallic element of the alkaline earth group; the fifth most abundant element in the earth's crust (3.6 per cent), occurring esp as forms of calcium carbonate. It is an essential constituent of bones and teeth and is used as a deoxidizer in steel. Symbol: Ca; ...

Moreover, CaO can react with humidity and form the hydroxide, another reversible reaction activated by heat, as forMgOin Equation(8.2). Despite the apparent high temperature of transformation, the transformation can occur by a triboreaction mechanism that apparently lowers the energy barrier. This re...
