<h3>Answer:</h3>

The Iron atom got oxidized.

<h3>Explanation:</h3>

In inorganic chemistry Oxidation and Reduction reactions are defined as,

Reduction:

The reaction in which an atom accepts electrons is known as reduction reaction.

Example:

2 Na + Cl₂ → 2 NaCl

In this reaction Chlorine oxidation state has changed from 0 to -1. Hence, it has gained one electrons therefore, it is designated as being reduced.

Oxidation:

The reaction in which an atom looses electrons is known as reduction reaction.

Examples:

2 Na + Cl₂ → 2 NaCl

In this reaction Sodium's oxidation state has changed from 0 to +1. Hence, it has lost one electrons therefore, it is designated as being Oxidized.

2 Fe + 3 O₂ → 2 FeO

In this reaction Iron's oxidation state has changed from 0 to +2. Hence, it has lost two electrons therefore, it is designated as being Oxidized.

Question 2 (0 points)

Answer:

The probability of spinning red with the spinner or rolling an odd number with the die is $\dfrac{1}{8}$

Explanation:

Given that,

Total color in spinner = 4

Let the area of four parts is equal in the spinner.

We need to calculate the probability of spinning red

Using formula of probability

$P(A) = \dfrac{Number\ of\ red\ color\ outcome}{Total\ number\ of\ colors\ in\ the\ spinner}$

Put the value into the formula

$P(A)=\dfrac{1}{4}$

We need to calculate the probability of odd number of the die

Using formula of probability

$P(B) = \dfrac{Number\ of\ odd\ digits\ outcome}{Total\ number\ of\ digits\ in\ the\ die}$

Put the value into the formula

$P(B)=\dfrac{3}{6}$

$P(B)=\dfrac{1}{2}$

We need to calculate the probability of spinning red with the spinner or rolling an odd number with the die

Using formula of probability of two events which is independent

$P(A\ and\ B)=P(A)\times P(B)$

Put the value into the formula

$P(A\ and\ B)=\dfrac{1}{4}\times\dfrac{1}{2}$

$P(A\ and\ B)=\dfrac{1}{8}$

Hence, The probability of spinning red with the spinner or rolling an odd number with the die is $\dfrac{1}{8}$
