How to balance calcium+water (gives) calcium …
How do you balance calcium+water (gives) calcium hydroxide+hydrogen gas? The unbalanced equation is Ca + H₂O → Ca(OH)₂ + H₂. Count the nuer of each type of atom on the left side, then see if those same nuers occur on the right side. (They have
The metal has a silvery color, is rather hard, and is prepared by electrolysis of the fused chloride to which calcium fluoride is added to lower the melting point. Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame, forming largely the nitride.
