Question

Mg + O2 РЕшите пожалуйста с помощью электронного баланса, и степени окисления расставьте ( или хотя бы просто степени )

Answer 1

Mg+O2=MgO Mgo -2e=Mg2+ | 2 | 4 O02. +4e =2O2- | 1 2Mgo+O2=2Mg2+2O2- 2Mg+O2=2MdO

Answer 2

Balancing the Chemical Equation for Mg + O2

To balance the chemical equation for the reaction between magnesium (Mg) and oxygen (O2), we need to ensure that the number of each type of atom is the same on both sides of the equation.

The unbalanced chemical equation is: Mg + O2 → MgO

To balance this equation, we can start by balancing the number of atoms of each element on each side of the equation.

Balancing the Equation Step by Step

1. Balancing Magnesium (Mg): There is one Mg atom on the left side and one Mg atom on the right side, so magnesium is already balanced.

2. Balancing Oxygen (O2): There are two O atoms in the O2 molecule on the right side, so we need to add a coefficient to the MgO on the right side to balance the oxygen atoms.

The balanced chemical equation is: 2Mg + O2 → 2MgO

Oxidation States of Magnesium and Oxygen

In the balanced chemical equation 2Mg + O2 → 2MgO, magnesium (Mg) has an oxidation state of +2, and oxygen (O2) has an oxidation state of -2.

This is consistent with the general rules for assigning oxidation states, where oxygen typically has an oxidation state of -2 in compounds, and magnesium, as an alkaline earth metal, typically has an oxidation state of +2.

Therefore, in the compound MgO, magnesium has an oxidation state of +2, and oxygen has an oxidation state of -2.

I hope this helps! If you have any further questions, feel free to ask.
