Question

what are the products formed when ethane burns in air? also write the a balanced chemical equation showing the types of energies liberated.

Answer 1

Reaction between ethane and air

• When ethane is burnt in the air it leads to the formation of carbon dioxide and water.
• Apart from these products, the reaction releases a high amount of heat and light in the form of energies.
• It is a combustion reaction as one of the reactants involved in the reaction is oxygen.
• The chemical reaction involved in the reaction is as follows:

$2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O$ + Heat + Light

• The number of atoms in the reactants side is

C = 4

H = 12

O = 14

• The number of atoms in the product side is

C = 4

H = 12

O = 14

• As the number of atoms in the reactant side is equal to the number of atoms in the product side the above-given equation is a balanced reaction.

Answer 2

Answer:

• when ethane burn in air to give carbon dioxide , water, heat and light is known as combination reaction 2C2H6 + 7O2 •••••••••••••••••••→ 4Co2 + 6H2O + heat + light there are two type of energy is liberate heat energy and light energy . I think it is help full for you.
