Question

when reaction of water with lime,which reaction takes place?

Answer 1

Answer:

readily with water to produce slaked lime, which is the chemical compound calcium hydroxide. A considerable amount of heat energy is released during this reaction. ... When carbon dioxide gas is passed through or over limewater, it turns milky due to the formation of calcium carbonate

Answer 2

$\huge{\sf{\underline{\underline{AnSwEr:-}}}}$

$\bullet$$\large{\sf{\underline{\underline{CheMicaL \: reacTions :-}}}}$

↪Chemical reactions are those process which involve chemical changes.

↪They also involve a rearrangement of atoms.

↪They are represented by a chemical and skeletal equation.

$\bullet$$\large{\sf{\underline{\underline{TyPes \: oF \: reacTions:-}}}}$

↪Combination reaction .

↪Decomposition reaction.

↪Displacement reaction .

↪Double displacement reaction .

↪Oxidation and reduction or redox reaction.

$\bullet$$\large{\sf{\underline{\underline{LeT's \: bacK \: To \: QueStion:-}}}}$

↪When Lime (or calcium oxide) reacts with water , calcium hydroxide is formed and heat is released .

↪This reaction is a type of Combination reaction ,as a single product is formed .

↪This reaction is also a exothermic reaction because heat is given out .

↪$\sf\ CaO + H_2O \to\ Ca(OH)_2 + Heat$

$\therefore\sf{\underline{Here :-}}$

$\rm\star\ Cao \to\ Calcium \: oxide(or Lime)$

$\rm\star\ Ca(OH)_2 \to\ Calcium \: hydroxide(or Slaked lime)$

$\rm\star\ H_2O \to\ Water$
