Question

Стыдно таким образом вопрос задавать,но я не могу хим. термином объяснить,что нужно сделать. Вот формула:Fe2O3+Mg=MgO+Fe.Это реакция и там нужно подставить какие-то цифры перед знаками букв.Надеюсь,истинный ценитель химии поймёт,что там нужно сделать.

Answer 1

Fe2O3 +3Mg = 3MgO + 2Fe

Answer 2

Balancing the Chemical Equation

The chemical equation you provided is: Fe2O3 + Mg = MgO + Fe. To balance this equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation.

Here's how you can balance the equation step by step:

1. Start by counting the number of atoms for each element on both sides of the equation. Currently, we have: - Fe: 2 on the left side, 1 on the right side - O: 3 on the left side, 1 on the right side - Mg: 1 on the left side, 1 on the right side

2. To balance the number of atoms of each element, you can adjust the coefficients in front of the chemical formulas. Let's start by balancing the Fe atoms: - Fe: 2 on the left side, 2 on the right side

3. Now, let's balance the O atoms: - O: 3 on the left side, 3 on the right side

4. Finally, let's balance the Mg atoms: - Mg: 1 on the left side, 1 on the right side

After balancing the equation, we have: Fe2O3 + 3Mg = 3MgO + 2Fe.

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.

Please note that the coefficients in front of the chemical formulas represent the number of molecules or moles of each substance involved in the reaction.
