Explanation:

Area of shaded region ≈ 95.2 square units, Area of entire circle ≈ 113.1 square units.

The circumference is the perimeter of a circle or ellipse in geometry. That is, the circumference would be the circle's arc length if it were opened up and straightened out to a line segment.

The first step is to find the measure of the central angle acb in radians:

Since the radius of circle c is 6 units, the diameter of the circle is 2*6 = 12 units. Therefore, the circumference of the circle is:

C = πd = π(12) = 12π units

The central angle acb cuts off a portion of the circumference that is proportional to its measure, so we can set up the following proportion to find the measure of the central angle in radians:

(angle measure)/(360°) = (arc length)/(circumference)

Where the arc length is the length of the portion of the circumference cut off by the central angle.

Substituting the given values, we get:

(angle measure)/360° = x/(12π)

Simplifying, we get:

(angle measure) = 360°(x/(12π)) = 30x/π

Now we can use this value to calculate the area of the entire circle and the area of the sector created by central angle acb:

Area of entire circle = [tex]\pi r^2[/tex] = π[tex](6)^2[/tex] ≈ 113.1 square units

Area of sector acb = (1/2)[tex](6^2)[/tex](angle measure) = (1/2)(36)(30x/π) = 540x/π square units

To find the area of the shaded region, we need to subtract the area of triangle abc from the area of sector acb.

The central angle acb is divided into two congruent angles of measure x/2, so the angle measure of triangle abc is (180° - x)/2. We can use the Law of Cosines to find the length of side ab:

[tex]ab^2[/tex] = [tex]ac^2 + bc^2[/tex] - 2acbc cos((180° - x)/2)

Substituting the given values, we get:

[tex]ab^2[/tex] =[tex]6^2 + 6^2[/tex] - 2(6)(6) cos((180° - x)/2)

Simplifying, we get:

[tex]ab^2[/tex] = 72 - 72 cos((180° - x)/2)

Taking the square root of both sides, we get:

ab = √(72 - 72 cos((180° - x)/2))

Now we can calculate the area of triangle abc:

Area of triangle abc = (1/2)ab(bc)sin((180° - x)/2)

Substituting the given values, we get:

Area of triangle abc = (1/2)(√(72 - 72 cos((180° - x)/2)))(6)(sin((180° - x)/2))

Finally, we can subtract the area of triangle abc from the area of sector acb:

Area of shaded region = Area of sector acb - Area of triangle abc

Area of shaded region = (540x/π) - (1/2)(√(72 - 72 cos((180° - x)/2)))(6)(sin((180° - x)/2))

Approximating with x = 1.5 radians (which is approximately 86°), we get:

Area of entire circle ≈ 113.1 square units

Area of sector acb ≈ 283.5 square units

Thus, the Area of shaded region ≈ 95.2 square units.

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

A small object built to scale that represents something larger is called a "scale model."

Explanation:

A scale model is a smaller version of an object or concept that accurately represents the proportions and features of the original on a reduced scale. It is a three-dimensional or virtual representation used for visualization, planning, and understanding complex structures or systems. Scale models allow us to study and interact with the object or idea in a more manageable form, making it easier to test and communicate ideas before actual production or construction. They are valuable tools in various fields, including architecture, engineering, design, and education.

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

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.
