## Which equation represent an oxidation-reduction reaction?

Expert-verified answer CH₄ + 2O₂ → CO₂ + 2H₂O is the equation that represents an oxidation-reduction reaction.

## How do you solve oxidation-reduction problems?

A redox equation can be balanced using the following stepwise procedure: (1) Divide the equation into two half-reactions. (2) Balance each half-reaction for mass and charge. (3) Equalize the number of electrons transferred in each half-reaction. (4) Add the half-reactions together.

What happens in redox reactions A&P?

What happens in a Oxidation-Reduction (Redox) Reaction? Electrons are transferred from one reactant to another and the oxidation states/oxidation number of certain atoms are changed.

How do you find the oxidation state of a transition metal complex?

To determine the oxidation state of the metal, we set the overall charge equal to the sum of the ligands and the metal: +1 = −2 + x, so the oxidation state (x) is equal to 3+.

### How do you write a reduction reaction?

Guidelines for Balancing Redox Equations:

1. Determine the oxidation states of each species.
2. Write each half reaction and for each:
3. Balance the number of electrons transferred for each half reaction using the appropriate factor so that the electrons cancel.
4. Add the two half-reactions together and simplify if necessary.

### Which equation represents reduction reaction?

The equation can also be written as PbO2(s)+4H+(aq)+SO42−(aq)+2e−→PbSO4(s)+2H2O(l)

What is oxidation chemical equation?

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

What type of reaction is a B energy → AB?

7.10: Classifying Chemical Reactions

Name of Reaction General Form
Exchange: Single Replacement AB + C → AC + B
Exchange: Double Replacement AB + CD → AD + CB
Combination (Synthesis) A + B → AB
Decomposition AB → A + B

## What happens in oxidation-reduction?

The oxidation-reduction or redox reactions involve the transfer of electrons between an electron donor (that becomes oxidized) and an electron acceptor (that becomes reduced).

## Why transition metals show variable oxidation states?

These elements show variable oxidation states because their valence electrons are in two different sets of orbitals, that is (n-1)d and ns. The energy difference between these orbitals is very less, so both the energy levels can be used for bond formation. Thus, transition elements have variable oxidation states.

What is the oxidation state of transition metals?

The highest oxidation state of chromium is +6. As we know the oxidation state of Zn is +2. It does not show a variable oxidation state. Therefore, does not consider a transition element….Oxidation State of Transition Elements.
