Question

Write the balance chemical equation: Iron filling react with steam to produced iron 3I oxide and hydrogen gas

Answer 1

Answer :—

★ A chemical equation :

A chemical equation can be simply defined as a symbolic representation of a chemical reaction. A chemical equation represents a chemical reaction in the form of symbols and formulae.

A chemical equation has two parts - the reactant side/part & the product side/part (these two parts are separated by an arrow).

★ The need for a balaced chemical equation :

• A balanced checmial equation is a chemical equation in which the number of atoms of each element is equal/same on both sides of the arrow.

• Every chemical equation should be balanced because all chemical reactions should follow the law of conservation of mass (mass can neither be created nor destroyed in a chemical reaction).

• Balancing chemical reactions also help us to know the quantity of reactants required for a chemical reaction and the quantity of the products obtained.

● Skeletal equation :

$\bold{Fe(s)+H_2O(g)----)Fe_2O_3(s)+H_2(g)}$

● Balanced equation :

$\bold{2Fe(s)+3H_2O(g)----)Fe_2O_3(s)+3H_2(g)}$
