Answer:

Option (A)

Explanation:

  • Contour plowing is usually defined as an efficient technique for plowing that is carried along the elevation contours of the land in the hilly areas in order to reduce the effect of soil erosion. It also improves the drainage pattern and improves the quality of the water.
  • No-till planting (farming) is a commonly used agricultural technique that does not involve the use of tillage, and enriches the fertility of the soil and also reduces the soil erosion effect.
  • Afforestation is a process characterized by the planting of new plants and trees in order to reduce the effect of soil erosion, and also increases the fertility of the soil.

Thus, all these three processes are mainly implemented in order to reduce soil erosion, which usually takes place due to agents like wind and water.

Hence, the correct answer is option (A).

Write out the mechanism for the reaction of the alkene side product with concentrated hydrochloric acid.
Marrrta [24]

The mechanism for the reaction of the alkene side product with concentrated hydrochloric acid  cannot easily abstract proton to form alkene.

We do not observe alkene side product because Cl- (chloride)  is a poor base which cannot easily abstract proton to form alkene.

For obtaining  alkene as product, Sulphuric acid H₂SO₄  is used.

Hydrochloric acid, additionally called muriatic acid, is an aqueous answer of hydrogen chloride. it is a drab solution with a specific pungent smell. Hydrochloric acid, additionally known as muriatic acid, is an aqueous solution of hydrogen chloride. Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (quick-term) inhalation publicity may also purpose eye, nostril, and breathing tract irritation and infection and pulmonary edema in humans.

A reaction mechanism is the collection of standard steps with the aid of which a chemical response occurs. A reaction that occurs in  or greater elementary steps is known as a multistep or complex response. A response intermediate is a chemical species that is fashioned in a single essential step and ate up in a subsequent step.

Consider the two gaseous equilibria: The values of the equilibrium constants K 1 and K 2 are related by
Sauron [17]

The question is missing parts. The complete question is as follows.

Consider the two gaseous equilibria involving SO2 and the corresponding equilibrium constants at 298K:

SO_{2}_{(g)} + \frac{1}{2}O_{2} ⇔ SO_{3}_{(g)}; K_{1}

2SO_{3}_{(g)} ⇔ 2SO_{2}_{(g)}+O_{2}_{(g)}; K_{2}

The values of the equilibrium constants are related by:

a) K_{1} = K_{2}

b) K_{2} = K_{1}^{2}

c) K_{2} = \frac{1}{K_{1}^{2}}

d) K_{2}=\frac{1}{K_{1}}

Answer: c) K_{2} = \frac{1}{K_{1}^{2}}

Explanation: <u>Equilibrium</u> <u>constant</u> is a value in which the rate of the reaction going towards the right is the same rate as the reaction going towards the left. It is represented by letter K and is calculated as:

K=\frac{[products]^{n}}{[reagents]^{m}}

The concentration of each product divided by the concentration of each reagent. The indices, m and n, represent the coefficient of each product and each reagent.

The equilibrium constants of each reaction are:

SO_{2}_{(g)} + \frac{1}{2}O_{2} ⇔ SO_{3}_{(g)}

K_{1}=\frac{[SO_{3}]}{[SO_{2}][O_{2}]^{1/2}}

2SO_{3}_{(g)} ⇔ 2SO_{2}_{(g)}+O_{2}_{(g)}

K_{2}=\frac{[SO_{2}]^{2}[O_{2}]}{[SO_{3}]^{2}}

Now, analysing each constant, it is easy to see that K_{1} is the inverse of K_{2}.

If you doubled the first reaction, it will have the same coefficients of the second reaction. Since coefficients are "transformed" in power for the constant, the relationship is:

K_{2}=\frac{1}{K_{1}^{2}}
