What kind of reaction do you think reaction represents?

ch3cooh+ nahco3 -> co2+ h2o++ch3coo−

what kind of reaction do you think reaction represents?

cacl2 + 2 nahco3 → co2 + caco3 + 2 nacl + h2o

1. Double displacement reaction

2. precipitation reaction.

Explanation:

Part 1

Reaction Given:

          CH₃COOH + NaHCO₃ > CO₂ + H₂O+ Na⁺ + CH3COO−

Reaction Type = ?

Solution:

In this reaction two reactant combine and give 3 products.

This reaction occur in two steps

In step one acetic acid react with sodium bicarbonate and gives sodium acetate plus carbonic acid.

         CH₃COOH + NaHCO₃ > H₂CO₃ + CH3COONa

So, the above reaction is a double displacement reaction. where sodium of sodium carbonate replace hydrogen of acetic acid and vice versa.

In step two the cabonic acid decomposes in two components that is carbon dioxide and water.

         H₂CO₃ > CO₂ + H₂O

The overall reaction is

      CH₃COOH + NaHCO₃ > CO₂ + H₂O + CH3COONa

As the CH3COONa exist in ions in solution so it can be written as

     CH₃COOH + NaHCO₃ > CO₂ + H₂O + CH3COO⁻ Na⁺

So, the overall reaction is a double displacement reaction.

This is a double displacement reaction, in which Hydrogen (H) of the first compound replace the Sodium (Na) of the other compound.

Part 2.

Reaction Given:

          CaCl₂ + 2 NaHCO₃ → CO₂ + CaCO₃ + 2 NaCl + H₂O

Solution

In this reaction two reactant combine and give 4 products.

Reactant of the reaction

CaCl₂  = calcium chloride

NaHCO₃ = sodium bicarbonate

Reactant of the reaction

CO₂= carbon dioxide

CaCO₃ = calcium carbonate

NaCl = sodium chloride

H₂O = water

So,

the reactant of the reaction that is calcium chloride react with sodium bicarbonate combine and form calcium carbonate and salt along with water and the evaluation of carbon dioxide.

As in this reaction calcium carbonate is formed in the form of precipitates so it is a precipitation reaction.

So

This is a type of precipitation reaction.
