Answer: C2H4 + 3O2 > 2CO2 + 2H2O

Explanation:

The law of conservation of mass has been given as the mass cannot be created nor be destroyed in a chemical reaction. The law of conservation of mass has equal weight of the reactants and the products.

The mass of following reactions can be given as:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

12g + 4(2)g   =   16g

20g = 16g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

3(18)   = 3(2) + 3(32)

54g = 102g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

2(23) + 36.5 = 58.5 g

81.5g = 58.5g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

The reaction that has been following the law of conservation of mass has been reaction 1. Thus, option 3 is correct.

Which of the following equations follows the Law of Conservation of Mass?

2Na + Cl > NaCl

C + 4H2 > CH4

C2H4 + 3O2 > 2CO2 + 2H2O

3H2O > 3H2 + 3O2

C2H4 + 3O2 > 2CO2 + 2H2O

The mass of the following reactions can be given:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
