Calcium - Periodic table
Calcium is reactive and, for a metal, soft. With a bit of effort, it can be cut with a sharp knife. In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal

Acid Rain Effects - Soils - Elmhurst University
Limestone Neutralization: The sulfuric acid reacts with the limestone in a neutralization reaction. Limestone: CaCO 3 + H 2 SO 4--> CaSO 4 + H 2 CO 3 The calcium sulfate is soluble in water and hence the limestone dissolves and crules. H 2 CO 3--> CO 2 gas + H 2 O
metal - Students | Britannica Kids | Homework Help
Calcium reacts vigorously with water, though not as vigorously as sodium and potassium. A few metal-water reactions vary with the temperature of the water. For example, magnesium reacts slowly with cool water, forming magnesium hydroxide and hydrogen gas.

20/3/2019· 1)Sodium is a very reactive metal,therefore sodium metal react violently even with cold water. Na + 2 H 2 O ———-> 2NaOH + H 2 2)Magnesium is less reactive metal so it react slowly with cold water,it reacts rapidly only with hot boiling water. Mg(s) + …
calcium | Definition, Properties, & Compounds | Britannica
The metal reacts slowly with oxygen, water vapour, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide.
What Metals React With Water to Produce Hydrogen? | …
When sodium metal reacts with water, the resulting heat melts the metal almost immediately into a grey-silver ball. The hydrogen gas evolved during this reaction propels the ball rapidly across the surface of the water, leaving a white trail of sodium hydroxide that eventually dissolves into a clear solution.
