Second Ionization energy is required to move from Ca⁺ to Ca²⁺ + e⁻. Hence, option D is correct.

<h3>What is first ionization energy?</h3>

First ionization energy: The energy needed to remove the outermost, or highest energy, an electron from a neutral atom in the gas phase.

An element's second ionization energy is the energy required to remove the outermost, or least bound, an electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first.

Let us write the reaction equation properly:

Ca⁺ → Ca²⁺ + e⁻

In the reaction above, we see that calcium goes from a single charge to being doubly charged by losing an electron.

Different atoms bind their valence electrons with different amounts of energy. We must supply enough energy to remove the most loosely held electrons in an atom. This amount of energy required is called ionization energy.

The first ionization energy removes the outermost electron and makes the atom to become an ion.

Hence, option D is correct.

In the following reaction, identify the oxidized species, reduced species, oxidizing agent, and reducing agent. Be sure to answe

Answer :

$Cl_2$ is reduced species.

$KI$ is oxidized species.

$Cl_2$ is oxidizing agent.

$KI$ is reducing agent.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.

The balanced redox reaction is :

$Cl_2(aq)+2KI(aq)\rightarrow 2KCl(aq)+I_2(aq)$

The half oxidation-reduction reactions are:

Oxidation reaction : $2I^-\rightarrow I_2+2e^-$

Reduction reaction : $Cl_2^++2e^-\rightarrow 2Cl^-$

From this we conclude that the $'KI'$ is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and $'Cl_2'$ is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.

Thus, $Cl_2$ is reduced species.

$KI$ is oxidized species.

$Cl_2$ is oxidizing agent.

$KI$ is reducing agent.

crimeas [40]

Answer:

B) The farther away from the Sun, the thinner a planet's atmosphere. Closer planets need more protection from the heat.

Explanation:

The planets closest to the Sun are the inner, or terrestrial, planets and are similar to Earth in some ways. They are rocky and dense, have few moons, no rings, and are relatively small. These planets also differ in many ways, as shown in the chart. For example, Venus is the hottest planet on the chart, even though Mercury is closer to the Sun. The temperature difference between Venus and Earth is significantly greater than the difference between Venus and Mercury, even though Venus lies close to midway between those two planets.
