Answer: Oxidation and Reduction Reactions.

Explanation: Redox Reaction is a type of reaction in which the oxidation reaction as well as the reduction reaction takes place simultaneously.

Oxidation reaction is the one in which one species loses electrons and appears as cation and reduction reaction is the reaction in which the other species accept electrons.

The one which loses electrons is known as Oxidizing Agent as it helps the other specie to accept electrons and the one which accepts electrons is known as Reducing Agent .

Every redox reaction consists of two parts, the oxidation and the reduction. Each one separately is called a half - reaction. During the redox reaction there is a transfer of electrons from the substance being oxidized to the substance being reduced. In a voltaic cell, these reactions happen in separate vessels.

C2H4 is oxidized and O2 is reduced in both reactions.

<h3>What is oxidation/reduction?</h3>

Oxidation is defined in several ways. Some of the definitions are:

The addition of oxygen or removal of hydrogen
Increase in the oxidation number of atoms
Addition of electronegative or the removal of electropositive elements

Reduction, on the other hand, is defined as:

Removal of oxygen or addition of hydrogen
Decrease in the oxidation number of atoms
Addition of electropositive elements or the removal of electronegative elements.

In the two reactions, oxygen is being added to C2H4. Thus, C2H4 is being oxidized.

The oxidizing agent is O2. In oxidation reactions, the oxidizing agents usually get reduced. Thus, O2 is reduced in both reactions.

Explain how you would decide which represents a greater mass: 3.25 x 1022 atoms of Ca or 2.45 grams of Mg?

elena55 [62]

Answer:

You need to convert the number of atoms of Ca into mass in grams, using Avogadro's number and the atomic mass of Ca.

Explanation:

The amount of matter is measured in grams. Thus, you need to convert the number of atoms of Ca (calcium) into mass to compare with 2.45 grams of Mg.

To convert the atoms of calcium into mass, you divide by Avogadro's number, to obtain the number of moles of atoms, and then divide by the atomic mass of calcium.

1. Number of moles, n

$n=\dfrac{\text{number of atoms}}{\text{Avogadro's number}}\\ \\ \\ n=\dfrac{3.25\times 10^{22}}{6.022\times 10^{23}}=0.053969mol$
