What is the coefficient of silver in the final, balanced equation for this reaction?
katovenus [111]

Answer: 3

Explanation:

An oxide-reduction reaction or, simply, redox reaction, is a <u>chemical reaction in which one or more electrons are transferred between the reactants</u>, causing a change in their oxidation states, which is the hypothetical electric charge that the atom would have if all its links with different elements were 100% ionic.

For there to be a reduction-oxidation reaction, in the system there must be an element that yields electrons and another that accepts them:

  • The oxidizing agent picks up electrons and remains with a state of oxidation inferior to that which it had, that is, it is reduced.
  • The reducing agent supplies electrons from its chemical structure to the medium, increasing its oxidation state, ie, being oxidized.

To balance a redox equation you must <u>identify the elements that are oxidized and reduced and the amount of electrons that they release or capture, respectively. </u>

In the reaction that arises in the question the silver (Ag) is reduced <u>because it decreases its oxidation state from +1 to 0</u> and the aluminum (Al) is oxidized because <u>its oxidation state increases from 0 to +3</u>, releasing 3 electrons (e⁻). Then we can raise two half-reactions:

Ag⁺ + e⁻ → Ag⁰

Al⁰ → Al⁺³ + 3e⁻

In order to obtain the balanced equation, we must multiply the first half-reaction by 3 so that, when both half-reactions are added, the electrons are canceled. In this way:

(Ag⁺ + e⁻ → Ag⁰ ) x3

Al⁰ → Al⁺³ + 3e⁻               +

-------------------------------------

3Ag⁺ + Al⁰ → 3Ag⁰ + Al⁺³

So, the coefficient of silver in the final balanced equation is 3.

Indicates which of the following radical chemical species and explains why
Zina [86]
Answer is: <span>(CH3)C.
Carbon has four bonds in organic compound.
1) in </span>(CH3)CH, carbon has four single bonds, one with hydrogen and three witn methyl group (CH₃), <span>so he is not radical.
2) in </span><span>(CH3)C, carbon has three single bonds and one free electron.
3) in </span>(CH3)C+, carbon has three single bonds and no free electrons, he is carbocation, not radical.
