Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium

How do you write the formula (overall) equation, the

How to find the Overall Equation: The given compounds are reactants: Calcium Chloride #(CaCl_2)# and Silver Nitrate #(AgNO_3^-)#.. To find the products, you simply coine the two ''inner'' and two ''outer'' elements together. In this case, the two ''inner'' elements are Silver and Chloride, while the two ''outer'' elements are Calcium and Nitrate.
