what happens when quick claim or calcium metal reacts with water
Answers
Answer:
the process becomes highly exothermic and thus produce heat
Answer:
Explanation:
Calcium + Water → Calcium hydroxide + Hydrogen Gas
[Chemical Equation]
Ca (s) + 2(H2O) (l) → Ca(OH)2(aq) + H2 (g)
Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal. Calcium is a member of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:
Ca(s) + 2H2O(l) ——> Ca(OH)2(aq) + H2(g)
In the following demonstration, a chunk of calcium metal is dropped into a beaker of distilled water. After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide. The presence of the hydroxide is demonstrated by the addition of a few drops of phenolphthalein indicator, which turns the solution pink, indicating that the solution is basic.
