Question

Given the reaction: C2H2 + 2H2 → C2H6 This reaction represents

Answer 1

Given  reaction:

C2H2 + 2H2 → C2H6

This reaction represents: Combination reaction

Explanation:

When two or more substances react and form some new substance it is called as chemical reaction .

A + B --> C + D

(reactants )   (products )

Types of chemical reaction

we come across different types of reactions that occur in nature .

Out of them , combination is also one type

Combination reaction

It is a reaction ,when two or more reactants react to form single product .

i.e A+B-----AB(IN THIS ONE SINGLE PRODUCT IS FORMED )

• This  reaction can be between element element , element compound or compound compound .  

LIKE : H₂+Cl₂------HCL

         (E)    (E)         (PRODUCT )

           SO₂+O₂----SO₃

             ©   (E)        (PRODUCT )

           CO₂+H₂O----H₂CO₃

In the above asked equation :

C₂H₂ + 2 H₂ --> C₂H₆

• The ethane is formed by combination reaction
• This reaction obeys law of conservation of mass as it is balanced .
