Answer 1

Answer:

exothermic reaction

Explanation:  

I think this because this is an example of an exothermic reaction is the chemical reaction between sodium and chlorine, which results in the formation of sodium chloride (also known as common salt)

Answer 2

In an exothermic reaction,

⇢The total energy of the reactants > the total energy of the product.

the diagram shows an exothermic reaction

• Exothermic reaction releases heat making it's surrounding hotter
• ∆H = -ve
