I can tell you for sure that resistant crop strains is not the correct answer. I believe it would be hydrocarbon substitution. Gene therapy has to do with the study of genetics, which is an example of biotechnology, and animal cloning involves genetics as well.

Review Problem 5.040 For each reaction, identify in order the substance oxidized, the substance reduced, the oxidizing agent, an

alexandr402 [8]

Answer:

A. The correct option is: Cu; H₂SO₄; H₂SO₄; Cu

B. The correct option is: SO₂; HNO₃; HNO₃; SO₂

C. The correct option is: Zn; H₂SO₄; H₂SO₄; Zn

D. The correct option is: I₂; HNO₃; HNO₃; I₂

Explanation:

A chemical reaction that involves the simultaneous transfer of electrons between two chemical species is known as the redox reaction.

In this reaction, a species that gains electrons, thus getting reduced is called the oxidizing agent. Whereas, species that loses electrons, thus getting oxidized is called the reducing agent.

Oxidation refers to an increase in the oxidation state and reduction refers to a decrease in the oxidation state.

A. Cu + 2H₂SO₄ → CuSO₄ + SO₂ +2H₂O

In this reaction, Cu goes from 0 in Cu to +4 oxidation state in CuSO₄ and thus gets oxidized. Whereas, S goes from +6 in H₂SO₄ to +4 oxidation state in SO₂ and thus gets reduced. Therefore, H₂SO₄ is the oxidizing agent and Cu is the reducing agent.

The correct option is: Cu; H₂SO₄; H₂SO₄; Cu

B. 3SO₂ + 2HNO₃ + 2H₂O → 3H₂SO₄ + 2NO

In this reaction, S goes from +4 in SO₂ to +6 oxidation state in H₂SO₄ and thus gets oxidized. Whereas, N goes from +5 in HNO₃ to +2 oxidation state in NO and thus gets reduced. Therefore, HNO₃ is the oxidizing agent and SO₂ is the reducing agent.

The correct option is: SO₂; HNO₃; HNO₃; SO₂

C. 5H₂SO₄ + 4Zn → 4ZnSO₄ + H₂S +4H₂O

In this reaction, Zn goes from 0 in Cu to +2 oxidation state in ZnSO₄ and thus gets oxidized. Whereas, S goes from +6 in H₂SO₄ to -2 oxidation state in H₂S and thus gets reduced. Therefore, H₂SO₄ is the oxidizing agent and Zn is the reducing agent.

The correct option is: Zn; H₂SO₄; H₂SO₄; Zn

D. I₂ + 10HNO₃ → 2HIO₃ + 10NO₂ + 4H₂O

In this reaction, I goes from 0 in I₂ to +5 oxidation state in HIO₃ and thus gets oxidized. Whereas, N goes from +5 in HNO₃ to +4 oxidation state in NO₂ and thus gets reduced. Therefore, HNO₃ is the oxidizing agent and I₂ is the reducing agent.

The correct option is: I₂; HNO₃; HNO₃; I₂

What unit is used to measure cell potential?

Lilit [14]

Volt is the unit to measure cell potential.

Explanation:

The cell potential is the measure of potential difference in the two halves of the electrochemical cell.

It is the measure of how much voltage exists between the two halves of the battery. The unit of volt is joule/coulomb. The cell potential is measured by voltmeter.

The energy per unit charge from the oxidation-reduction reaction to drive the reaction is cell potential.

Which of the following occurs when the ocean’s salinity increases?

eimsori [14]

Answer: Option (a) is the correct answer.

Explanation:

The measure of amount of salt dissolved in ocean is known as ocean’s salinity.

Therefore, when salinity increases then mass of salt in the ocean increases as a result the density will increase.

As density is the mass per unit volume of a substance. Mathematically, it is as follows.

$Density = \frac{mass}{volume}$

Therefore, when mass increases then density will increase as there is no change in volume.

Whereas salinity increases when there is an increase in temperature as more salt will dissolve then in the ocean but due to increase in salinity there will be no effect on temperature. Hence, temperature will neither increase or decrease due to the increase or decrease in salinity of ocean.

Thus, we can conclude that when the ocean’s salinity increases then the density increases.
