For a 1.0×10−6 m solution of hno3(aq) at 25 °c, arrange the species by their relative molar amounts in solution.
The relative order of molar amounts since the solution is aqueoeus with H₂O having more concentration is; H₂O > H₃O⁺ = NO₃⁻ > OH⁻ > HNO₃
What is the relative molar amount?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

Water has the ability to store heat longer than other substances. What benefit does this property of water provide to organisms?
Answer:
The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances. As the temperature rises, the hydrogen bonds between water continually break and reform, allowing for the overall temperature to remain stable, although increased energy is added to the system

The radius of circle c is 6 units and the measure of central angle acb is radians. What is the approximate area of the entire circle? square units what is the approximate area of the entire sector created by central angle acb? square units what is the approximate area of the shaded region only? square units.
Answer:
113
28
22
Explanation:
Area of shaded region ≈ 95.2 square units, Area of entire circle ≈ 113.1 square units.
What is circumference?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.

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

Small object usually built to scale that represents
Answer:
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.
Consider the reaction n2 + 3 h2 → 2 nh3. How much nh3 can be produced from the reaction of 74. 2 g of n2 and 14. 0 moles of h2?
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
