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.

<span>Since each of these orbitals can hold a maximum of </span>two electrons<span>, one having spin-up and one having spin-down, a total of </span>10 electrons<span> can share the quantum numbers n = 4 and l = 2</span>
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.
Answer:
The answer to your question is: "react with acids to produce hydrogen gas"
Explanation:
Chemicals properties of matter: are properties that can be measured if there is a chemical change or chemical reaction.
Examples of chemical reactions:
Reactivity
Toxicity
Coordination number
Flammability
Of the properties listed, the only that implies a reaction is "react with acids to produce hydrogen gas"
