The reducing agent is a substance loses electrons in a chemical reaction

$\boxed{\boxed{\bold{Further~explanation}}}$

The oxidation-reduction reaction or abbreviated as a redox is a chemical reaction in which there is a change in oxidation number

3 basic theories explain this Redox concept:

1. Binding/release of oxygen

The oxidation reaction is the binding of substance with oxygen. (O₂)

For example:

2SO₂ + O₂ ----> 2SO₃

The reduction from oxygen from a substance.

For example:

2CuO → 2Cu + O₂

2. Electron release / binding reaction

Oxidation is an electron release event

Example:

2F ---> 2Fe³⁺ + 6e⁻

The reduction is an electron capture event

Example:

3O₂ + 6e⁻ ---> 3O²⁻

3. The reaction of addition/reduction of oxidation number

Oxidation increases in oxidation number, while reduction is a decrease in oxidation number.

We see the answer choices :

a) the one that is oxidized, which is the oxidizing agent

The oxidizer is a substance that is reduced, so it's a false statement

b) the one that is reduced, which is the reducing agent

Reducing agents are substances that experience oxidation, so wrong statements

c) the one that is oxidized, which is the reducing agent

The statement is true because the Oxidation is an electron release event and occurs in the reducing agent

d) the one that is reduced, which is the oxidizing agent

The statement is wrong because the reduction process is electron capture so the oxidation number drops

chemical reactions are an oxidation-reduction reaction

the reduction process

an element's oxidation

an element's oxidation number increase

Answer from: Quest

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

Answer from: Quest

the temperature of the gas, in k, not celsius.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
