<u>Answer: </u>The reducing agent of the given chemical reaction is

<u>Explanation:</u>

Reducing agent is defined as the agent which reduces the other substance and itself gets oxidized. It undergoes oxidation reaction. Oxidation reaction is defined as the reaction in which a substance looses its electron. The oxidation state of the substance gets increased.

Oxidizing agent is defined as the agent which oxidizes the other substance and itself gets reduced. It undergoes reduction reaction. Reduction reaction is defined as the reaction in which a substance gains electron. The oxidation state of the substance gets reduced.

For the given chemical reaction:

CrO_3+2Al\rightarrow Cr+Al_2O_3

On reactant side:

Oxidation state of chromium = +5

Oxidation state of aluminium = 0

Oxidation state of oxygen = -2

On product side:

Oxidation state of chromium = 0

Oxidation state of aluminium = +3

Oxidation state of oxygen = -2

As, oxidation state of aluminium is getting increased from 0 to +3. Thus, it is getting oxidized and considered as reducing agent. The oxidation state of chromium is getting reduced from +5 to 0. Thus, it is getting reduced and is considered as oxidizing agent.

Hence, the correct answer is aluminium.

Give the name and formula of the compound formed from the following elements:<br> (b) ₃₀L and ₁₆M
madam [21]

When sulfur reacts with zinc metal is forms a compound known as zinc sulfide.

<h3>Name of the elements</h3>

The names of the elements that make up the compound will be determined from the atomic mass of the elements.

<h3>Which element has atomic number 30</h3>

The element that atomic number of 30 is zinc and it has oxidation number of +2.

<h3>Which element has atomic number 16</h3>

The element that atomic number of 16 is sulfur and it has oxidation number of -2.

<h3>Chemical reaction between sulfur and zinc metal</h3>

Zn²⁺ + S²⁻  --------> ZnS

Thus, when sulfur reacts with zinc metal is forms a compound known as zinc sulfide.

Compare and contrast a pure substance with a mixture and give an example.
Inessa [10]

Of any substance? What about two powders such as 1/2 cup of white flour, then mixing 1/2 cup of salt together with the flour. This would then form a more coarse mixture being that the two particles differ in shape.

nata0808 [166]
Answer:
            Ethyl alcohol is soluble in water because <span>ethyl alcohol exhibits dipole-dipole and h-bonding interactions with water.

Explanation:
                   Ethyl alcohol and water are miscible in each other because both are polar in nature and "Like dissolves Like".
                   The bond between oxygen and hydrogen atoms, both in alcohol and water are polar in nature and results in intermolecular hydrogen bond interactions between them as hydrogen bonding results when hydrogen atom in one molecule directly attached to highly electronegative atoms like fluorine, oxygen and nitrogen forms interaction with higly electronegative atom of neighbor atom.</span>
