Answer:

The oxidation number of iron changes from 2+ to 0.

10 electrons are transferred in the reaction.

Explanation:

Step 1: Write the balanced redox reaction

5 Fe²⁺ + 2 Mn²⁺ + 8 H₂O ⇒ 2 MnO₄⁻ + 5 Fe + 16 H⁺

Step 2: identify both half-reactions

Reduction: 5 Fe²⁺ + 10 e⁻ ⇒ 5 Fe

Oxidation: 2 Mn²⁺ + 8 H₂O ⇒ 2 MnO₄⁻ + 16 H⁺ + 10 e⁻

Step 3: Identify the oxidation state change of iron

Iron changes from Fe²⁺ to Fe, that is, the oxidation number changes from 2+ to 0.

Step 4: Determine how many electrons are transferred in the reaction?

According to both balanced half-reactions, 10 electrons are transferred in the reaction.

When the following equation is balanced using the smallest possible integers, what is the number in front of the substance in bo
weeeeeb [17]

The balanced equation :

8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe

You just have to look for which element is in bold because the question is not clear

<h3>Further explanation</h3>

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

Al + Fe₃O₄→ Al₂O₃ + Fe

give a coefficient

aAl + Fe₃O₄→ bAl₂O₃ + cFe

O, left=4, right=3b⇒3b=4⇒b=4/3

Al, left=a, right=2b⇒a=2b⇒a=2.4/3⇒a=8/3

Fe, left=3, right=c⇒c=3

The equation becomes :

8/3Al + Fe₃O₄→ 4/3Al₂O₃ + 3Fe x3

8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe

What atom has 8 protons and 10 electrons?
Lorico [155]

Answer:

In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total 2 xx (1-) = 2- net charge. Therefore, you are dealing with an anion that carries a 2- net charge, i.e. it has two more electrons than it does protons.
