Answer 1

Single Replacement reaction

Step-by-step explanation:

Reaction Given:

2Na + 2HCI ------> H₂ + 2NaCl

Type of reaction = ?

Solution:

Look at the reactants and products of the reaction to know the type of reaction

2Na + 2HCI ------> H₂ + 2NaCl

In this reaction two reactant combine and give 2 products.

Reactant of the reaction

Na = Sodium

HCl = Hydrochloric acid

Product of the reaction

NaCl = sodium chloride

H₂ = hydrogen gas

So,

That sodium metal react with hydrochloric acid and produce salt and water gas

Type of Reaction:

This is a Single Replacement reaction, in which Sodium metal (Na) replace the Hydrogen (H) of the other compound and form Sodium Chloride salt (NaCl) and hydrogen liberate in the form of gas.
