Question

Balance the following chemical equation: $Fe{\text{ }} + {\text{ }}{H_2}O{\text{ }} \to {\text{ }}F{e_3}{O_4}{\text{ }} + {\text{ }}{H_2}$

Answer 1

A chemical reaction is a process that results in the chemical change of one set of chemical substances into another set of chemical substances. Chemical reactions are often defined as changes in the locations of electrons in the formation and breaking of chemical bonds between atoms, with no change in the nuclei (no change in the elements present), and may be represented using a chemical equation.

Complete answer:
On the reactant and product sides of a balanced chemical equation, there are equal quantities of atoms for each element involved in the reaction. This is a condition that the equation must meet in order to be compatible with the conservation of matter rule. It may be verified by adding the numbers of atoms on both sides of the arrow and comparing them to check that they are equal.
How to Balance a Chemical Equation
The Unbalanced Chemical Equation is the first step.
Step 2: Create a to-do list.
Step 3: Identifying Each Element's Atoms
Multiplying the number of atoms is the fourth step.
Putting Coefficients in Front of Molecules (Step 5)
Step 6: Double-check the equation.
Step 7: Create a chemical equation that is balanced.
Hence here the chemical equation is
$3Fe{\text{ }} + {\text{ }}4{H_2}O{\text{ }} \to {\text{ }}F{e_3}{O_4}\; + {\text{ }}4{H_2}$

Note:
The chemical composition$F{e_3}{O_4}$ stands for iron(II,III) oxide. Magnetite is a mineral that occurs naturally. Iron(II) oxide (FeO), which is uncommon, and iron(III) oxide ($F{e_2}{O_3}$), which also occurs naturally as the mineral hematite, are two further types of iron oxides. It is also written as FeO $F{e_2}{O_3}$ since it includes both $F{e^{2 + }}$ and $F{e^{3 + }}$i ons. In the laboratory, this iron oxide appears as a black powder. It is ferrimagnetic and has permanent magnetism, yet it is frequently mistakenly referred to as ferromagnetic.
