<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}
