Question

What do u mean by combination and exothermic reaction

Answer 1

Answer:

The chemical reactions release energy in the form of heat, light, or sound, are called exothermic reactions. An exothermic reaction occurs when the temperature of a system increases due to the evolution of heat. This heat is released into the surroundings, resulting in an overall negative quantity for the heat of reaction.

An example of an exothermic reaction is the mixture of sodium and chlorine to yield table salt. This reaction produces 411kJ of energy for each mole of salt that is produced:

2Na(s)+Cl

(s)→2NaCl(s)+energy

$\Large\fbox{\color{purple}{ SOLUTION }}$

★ COMBINATION REACTION ★

IT IS A TYPE OF REACTION IN WHICH TO OR MORE REACTANTS FORM ONE COMPOUND IN PRODUCT SIDE

FOR EXAMPLE :-

2H2 + O2 ---------→ 2H2O

★ EXOTHERMIC REACTION ★

IT IS A TYPE OF REACTION IN WHICH A LARGE AMOUT OF HEAT IS RELEASED DURING THE REACTION

FOR EXAMPLE :-

C + O2 ------→ CO2
