Calcium hypochlorite | Ca(ClO)2 - PubChem

Calcium hypochlorite appears as a white granular solid (or tablets compressed from the granules) with an odor of chlorine. Toxic, irritating to the skin. Noncoustible, but will accelerate the burning of coustible materials. Prolonged exposure to fire or heat may result in the vigorous decomposition of the material and rupture of the container.

Calcium Metal - an overview | ScienceDirect Topics

Smelting to give the metals involves metallothermic reduction of fluorides or oxides, or electrochemical methods. Metal oxides are converted to fluorides by HF/Ar and purified by melting in an HF/Ar atmosphere. The fluorides are then reduced by the more electropositive calcium metal. 2 LnF 3 + 3 Ca → 3 CaF 2 + 2 Ln.

Rates of Reaction - Nuffield Foundation

Understanding the rates of chemical reactions is important for controlling reactions in industry. In this lesson sequence students will evaluate collision theory as a model for predicting rates of reactions. They then collect data to determine the order of the reaction of calcium carbonate and hydrochloric acid, and deduce the rate equation.
