Explain the following reaction with the help of balanced equation Calcium reacts with water​

Answer»

:When calcium and water reacts HYDROGEN gas is evolved and calcium hydroxide is formed.Explanation :Calcium is a reactive metal, when water ( H₂O ) reacts with calcium ( Ca ) it reacts with forming BUBBLES, and releases hydrogen ( H₂ ) gas and calcium hydroxide is formed. The word equation is :-Calcium (s) + Water (aq) → Calcium hydroxide (aq) + Hydrogen (g) ↑The balanced equation is :-Ca + 2H₂O → Ca ( OH )₂ + H₂↑Additional informationReaction with water [ resulting hydrogen gas ]Many reactive METALS like potassium, sodium, calcium reacts with water to produce hydrogen.For example ::-2Na + 2H₂O (water) → 2NaOH + H₂↑2K + 2H₂O (water) → 2NaOH + H₂Reaction with steam [ resulting hydrogen gas ]Some metals such as MAGNESIUM, zinc, iron react with steam to produce hydrogen gas.For example ::-Mg + H₂O (steam) → MgO + H₂↑Zn + H₂O (steam) → ZnO + H₂↑Reaction with dilute acid [ resulting hydrogen gas ]Some metals like magnesium, zinc, iron, etc. react with dilute hydrochloric acid or dilute SULPHURIC acid to produce hydrogen gas.For example ::-Zn + 2HCl → ZnCl₂ + H₂
