Explanation:

We know that 150 > 100, so the integer has to be > 10.

11² = 121

12² = 144

13² = 169

As you can see, the two integers that have 150 between their squares is 12 and 13.

(If we were to put the square root of 150 in a calculator, we would get 12.247... which is between 12 and 13).

The option that best explains why soil salinization is a concern in the arid landscape is; Irrigation increases the salt content of the soil, which disrupts the growth of crops and degrades soil fertility.

Soil salinization is defined as the accumulation of water-soluble salts within soil layers above a certain level.

Now, an Increase in soil salinity will lead to total crop failure in a field due to the fact that plants need to take up water from the soil for growth and development. However the salinity levels of this soil will draw water from the plants by osmosis since the soil water will be hypertonic to the plant's cells cytoplasm as well as seeds.

In osmosis, water moves from the hypotonic solution to the hypertonic solution via a semi-permeable membrane until osmotic equilibrium is achieved. Thus, planted seeds will find it hard to germinate and plants will wilt and die as a consequence.

The missing options are;

A) Forests are being cleared as land is re purposed for agricultural uses, which reduces biodiversity in the region.

B) Land is being farmed so intensively that soil nutrients are degraded to the point that crops will not grow.

C) Irrigation increases the salt content of the soil, which disrupts the growth of crops and degrades soil fertility.

D) Fields are left fallow after being farmed intensively so that nutrients in the soil may be replenished.

E) Multiple crops are being planted into the same field, which increases the chances of pest damage.

Explanation:

Convert 74.2 g N₂ to moles. (N₂ molar mass ≈ 28.014 g/mol)

(74.2 g) (1/28.014 mol/g) ≈ 2.65 mol N₂

According to the balanced reaction, 1 mol N₂ and 3 mol H₂ get consumed together to produce 2 mol NH₃, which means we consume up to

3 (2.65 mol N₂) ≈ 7.95 mol H₂

That is, all the N₂ is consumed and we have an excess of about 6.05 mol H₂. We end up with

2 (2.65 mol N₂) ≈ 5.30 mol NH₃

or (with NH₃ molar mass ≈ 17.031 g/mol)

(5.30 mol) (17.031 g/mol) ≈ 90.3 g NH₃

The only option that modernism didn't focus on is; A: Appreciation of Nature

Literary modernism originated in the late 19th and early 20th centuries primarily in Europe and North America. Modernism is characterized by a self-conscious break with traditional ways of writing, in both poetry and prose fiction writing.

The modernist movement was not in line with the previous Romantic period due to the fact that one focused on nature and existence while the modernist authors were more focused on the inner self and consciousness.

The relative order of molar amounts since the solution is aqueoeus with H₂O having more concentration is; H₂O > H₃O⁺ = NO₃⁻ > OH⁻  > HNO₃

Since the solution is aqueoeus, it means that H₂O has more concentration.

Now, since HNO₃ is a strong acid, it will completely dissociate. Thus;

HNO₃ + H₂O ⇒ H₃O⁺ + NO₃⁻

In the reaction above, HNO₃, H₂O, H₃O⁺, NO₃⁻ and OH⁻ are present. Since concentration of each ion is given as 1 * 10⁻⁶ M, then;

Concentration of OH⁻ is gotten from the formula;

k_w = [H₃O⁺][OH⁻]

Thus;

1 * 10⁻¹⁶ = [1 * 10⁻⁶] * [OH⁻]

[OH⁻] = [1 * 10⁻¹⁶]/[1 * 10⁻⁶]

[OH⁻] = 1 * 10⁻⁸

Thus, relative order of molar amount is;

H₂O > H₃O⁺ = NO₃⁻ > OH⁻  > HNO₃
