Question

Fe+H2O+O2=Fe(OH)3 Пожалуйста, объясните как тут коэффициенты расставлять, я уже посмотрела какие должны быть, но мне именно объяснение нужно, пожалуйста даю 28 баллов

Answer 1

4Fe + 6H₂O + 3O₂ = 4Fe(OH)₃

В соединении "Fe(OH)₃" железо имеет заряд +3, но молекулярный кислород(O₂) может забрать 4 электрона.

Следовательно, железа необходимо в 4 раза больше, а молекулярного кислорода в 3. (Можно расписать методом электронного баланса).

В соединении "Fe(OH)₃" 3 атома кислорода забрали 6 электронов(3 у водорода и 3 у железа), а для 4 молекул гидроксида железа водорода недостаточно, поэтому водорода нужно в 2 раза больше, чем молекулярного кислорода.

Answer 2

Balancing the Chemical Equation Fe + H2O + O2 = Fe(OH)3

Balancing a chemical equation involves ensuring that the same number of each type of atom is present on both sides of the equation. In the given chemical equation Fe + H2O + O2 = Fe(OH)3, we need to balance the equation by adjusting the coefficients of the compounds.

First, let's break down the equation into its individual components: - Fe: Iron - H2O: Water - O2: Oxygen - Fe(OH)3: Iron(III) hydroxide

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Step-by-Step Balancing Process:

1. Start by balancing the elements that appear only once on each side of the equation. In this case, we can begin with Iron (Fe) and Hydrogen (H). 2. Balance the Iron atoms first. We have one Iron atom on the left side and one Iron atom in Fe(OH)3 on the right side, so Iron is already balanced. 3. Next, balance the Hydrogen atoms. There are two Hydrogen atoms in H2O and three in Fe(OH)3, so we need to balance the Hydrogen atoms by adjusting the coefficient of H2O.

Balanced Chemical Equation:

The balanced chemical equation for the reaction Fe + H2O + O2 = Fe(OH)3 is: Fe + 4H2O + 3O2 = 2Fe(OH)3

This balanced equation ensures that the number of atoms of each element is the same on both sides of the equation, satisfying the law of conservation of mass.

I hope this explanation helps! If you have further questions or need clarification on any part, feel free to ask.
