A

(a)`4H+O_(2) rarr 2H_(2)O`

B

(b)`H_(2)+O rarr 2H_(2)O`

C

(c )`2H+O_(2) rarr 2H_(2)O`

D

(d)`Both (b) and (c )`

Text Solution

Verified by Experts

The correct Answer is:
a

According to law of conservation of mass, in all chemical changes the total mass of the system remains constant or in a chemical reaction, mass is neither be created nor be destroyed. This law was proposed by Lavosier and tested by Landolt.
But in (b) and (c ), mass of reactants is not equal to the mass of products.
