Question

Name the type of chemical reaction represented by the following equation and

write the balanced chemical equation.
a) CaO ( s) + H2O(l) Ca ( OH )2(aq)

b) H2 O (l)

electricity H2 (g ) + O2 (g)

c) Zn (s) + AgNO3 (aq) Zn (NO3)2(aq) +Ag (s)​

Answer 1

$\Large{\boxed{\underline{\bf{AnswEr:-}}}}$

$\sf{ CaO (s) + H_2O(l) \rightarrow Ca(OH)_2(aq)}$

【Combination Reaction】

$\sf{2H_2O(l) \: \: \underrightarrow{electricity} \: \: 2H_2(g) + O_2(g)}$

【Decomposition Reaction】

$\sf{ Zn(s) + 2AgNO_3(aq) \rightarrow Zn(NO3)_2(aq) +2Ag(s)}$

【Displacement Reaction】

More To Know!

✧ Combination Reaction ➝ When two or more substances combine to form a single product, the reaction is called Combination Reaction.

✧ Decomposition Reaction ➝ When a single reactant break down to give simpler products, the reaction is called Decomposition Reaction.

✧ Displacement Reaction ➝ When more reactive element displaces the less reactive element, this reaction is called Displacement Reaction.
