Question

balance equation:
Fe+O2↪️Fe2O3​

Answer 1

Explanation:

Balanced reaction:

4Fe + 3O₂ → 2FeO₃

Above reaction is an example Combination reaction.

Answer 2

Explanation:

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.

The Law of conservation of mass governs the balancing of a chemical equation.

According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side.

Given the equation: Fe + O2 → Fe2O3

Fe + O2 → Fe2O3 is the unbalanced form of the chemical reaction.

Balancing the simple molecules first, in this case, the O2

Fe + 3O2→ Fe2O3 there are now 6 O atoms on the left, there must also be 6 O atoms on the right.

Fe + 3O2 → 2Fe2O3

Balance the rest of the equation.

4Fe + 3O2→ 2Fe2O3
