The reaction forms calcium hydroxide, Ca(OH)2 and hydrogen gas (H2). Explanation:

When 10.0 g of calcium metal is reacted with water, 5.00 g

Calcium oxide reacts with water in a coination reaction to produce calcium hydroxide: CaO(s) + H2O(l) → Ca(OH)2(s)In a particular experiment, a 4.00-g sample of CaO is reacted with excess water and 4.79 g of Ca(OH)2 is recovered.

Reactions of metals with water - Metals and reactivity

Calcium reacts readily with water. calcium + water ➞ calcium hydroxide + hydrogen Ca (s) + 2H2O (l) ➞ Ca (OH)2(aq) + H2(g) Calcium hydroxide is slightly soluble in water so once the solution is

Reaction of Metals with Water, Steam and Dilute Acids

The more reactive metals tend to react with cold water to form metal hydroxide (alkaline solution) and hydrogen gas. This reaction can be easily represented by the following word equation: Metal + Water → Metal Hydroxide + Hydrogen Gas. Note that a more reactive metal will react more violently with cold water.

Calcium, Chemical Element - structure, reaction, water

Calcium is a fairly soft metal with a shiny silver surface when first cut. The surface quickly becomes dull as calcium reacts with oxygen to form a coating of white or gray calcium oxide. Calcium''s melting point is 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F). It has a …
