I am math tutor in delhi

The correct option is A Both (A) and (R) are true and (R) is the correct explanation of the assertion (A). Here the number of moles of atoms on both sides (reactant and product) is the same. Therefore, the chemical equation is balanced. Thus the assertion is true. Law of conservation of mass states that...

Therefore, the chemical equation is balanced. Thus the assertion is true. Law of conservation of mass states that mass can neither be created nor be destroyed, it can only be transformed from one form to another in a chemical reaction. Here in the reaction, the number of moles of atoms on both sides (reactant and product) is the same. Thus the reason is also true and is the correct explanation for the assertion. read less

Both assertion(A) and reason(R) are correct and assertion is the correct explanation for reason. Iron metal(Reactive Metal)displaces hydrogen from water leading to the formation of iron(III) oxide(solid precipitates) and the liberation of hydrogen gas, the reaction takes place for a long duration.The formation of iron oxide from iron and water is called the rusting of iron.The brown color layer that forms on the iron is iron oxide. The law of conservation of mass states thatin a chemical reaction mass is neither created nor destroyed holds true for this equation. read less

Explanation for reason:- Law of conservation of mass states that mass can neither be created nor be destroyed, it can only be transformed from one form to another in a chemical reaction.Thus for a chemical equation to obey the law of conservation of mass, it has to be balanced.Here in the reaction, the number of moles of atoms on both sides (reactant and product) is the same. Therefore, the mass of the reactants is the same as the mass of the products. Thus law of conservation of mass holds good for a chemical equation. Thus the reason is also true and is the correct explanation for the assertion. read less

The provided chemical equation accurately represents the reaction between steam and iron, yielding iron(II,III) oxide (Fe3O4) and hydrogen gas. This equation aligns with the law of conservation of mass, ensuring that the total number of atoms for each element remains constant on both sides of the reaction,...

11th grader with 100% in French 10th boards

Both Assertion and Reason are correct and Reason is correct explanation of Assertion It is so because we know that law of conservation of mass states that mass of reactants is conserved in a chemical reaction i.e mass of reactants= mass of products.
