Question

18. Complete the following reactions,
(1) Ca0(s) + H2O(l) ►
(2) CH3COOH(aq) + NaOH(aq)

Answer 1

Required Answers:-

The following are the complete reactions of the above:

$[1] \: \boxed{\rm{CaO + H_2O \longrightarrow \: Ca(OH)_2}}$

1. The above reaction is listing down Calcium oxide (or quick lime) and water as the reactant.
2. Calcium hydroxide (slaked lime) is the product in this case.
3. A large amount of heat is evolved. Hence, it is a exothermic reaction$.$

$[2] \: \boxed{ \rm{ CH_3COOH + NaOH \longrightarrow \: CH_3COONa + H_2O}}$

1. Acetic acid is a weak acid and Sodium hydroxide is a strong base.
2. The resultant is Sodium acetate which is a basic salt.
3. The above process is a neutralisation reaction.

Answer 2

The following reactions are the complete reactions of the above given reactions ►

$(1) \: {\boxed{\boxed{\bf{CaO + H_2O \rightarrow \: Ca(OH)_2}}}}$

$(2) \: {\boxed{\boxed{\bf{CH_3COOH + NaOH \rightarrow \: CH_3COONa + H_2O}}}}$

★ There are so many type of reactions. Some type of reactions are given below :-

• Decomposition reaction.

In this reaction compound either of it's own or upon heating decomposes to give two or more components out of which at least one is in the element state.

• Combination reaction.

In this reaction, compound are formed as a result of the chemical combination of two or more elements.

• Displacement reaction.

In this reaction an atom/ion present in a compound get replaced by an atom/ion of another element.

• Neutralization reaction.

When an acid react with a base, salt and water is formed. This reaction is known as neutralization reaction.

• Substitution reaction.

In this reaction, one or more atom kr group present in the organic molecule get substituted or replaced by suitable atom or group
