assertion(a): following is a balanced chemical equation for the action of steam on iron : 3Fe + 4H2O gives Fe3O4 + 4H2.
Reason(r): the law of conservation of mass holds good for a chemical equation
(a) both a and r is true and r is correct explanation of a
(b) both a and r is true and r is not the correct explanation of a
(c) a is true but r is wrong
(d) a is wrong but r is true

Answer:
Hey friend
Here is your answer
When steam is passed over red hot iron, iron (II, III) oxide is formed and hydrogen gas is released.
3Fe+4H2O=>Fe3O4+4H2
Hope it will helps you
a) The given assertion and reason both are true. Also R is correct explanation of A.
The Assertion given is : Following is a balanced chemical equation for the action of steam on iron 3Fe + 4H2O ⇒ Fe3O4 + 4H2
The Reason given is : The Law of conservation of mass holds good for a chemical equation.
Assertion involves a balanced chemical equation, which has equal number of moles of each element before and after the reaction.
Law of conservation of mass states that ; Mass can neither be created nor be destroyed in a chemical reaction.
A chemical equation is termed as Balanced chemical equation if it has same total mass of elements going under reaction, and total mass of elements after the reaction.
