Answer:

\( \huge 3.986 \times { 10}^{ - 5} \: \: mol \\ \)

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

\(n = \frac{N}{L} \\\)

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

A chemist determines that a substance is composed of 30.4% nitrogen by mass and 69.6% oxygen by mass. The molar mass of the compound is 230.5 g/mol, the molecular formula is NO₂.

We must compute the empirical formula in order to ascertain the compound's chemical composition.

If we have 100 grams of the compound.

This suggests we have:

30.4 g of nitrogen

69.6 g of oxygen

Now, we have to convert the mass of each element to moles.

The molar mass of nitrogen (N) = 14.01 g/mol

the molar mass of oxygen (O)  =  16.00 g/mol.

Number of moles of nitrogen (N):

2.17 mol

Number of moles of oxygen (O):

4.35 mol

The simplest whole-number ratio between the moles of nitrogen and oxygen must now be determined. To calculate the ratio, we divide both numbers by the smaller value.

Moles N / moles O = 2.17 mol / 2.17 mol = 1.00

Moles O / moles O = 4.35 mol / 2.17 mol = 2.00

The ratio is approximately N₁O₂.

We divide the subscripts by their greatest common divisor to obtain the simplest ratio, since we are looking for the empirical formula. The empirical formula is NO₂ since the greatest common divisor in this situation is 1.

The molecular formula of the compound is NO₂.

The average atomic mass of titanium on the given planet is approximately 46.68164 atomic mass units (u). The average atomic mass may vary depending on the specific isotopic composition of titanium found on different celestial bodies or regions.

To calculate the average atomic mass of titanium on the given planet, we need to consider the natural abundances and masses of each isotope of titanium.

The average atomic mass is calculated by multiplying the natural abundance of each isotope by its respective mass and summing them up.

Let's perform the calculation step by step:

Step 1: Multiply the abundance of each isotope by its mass:

(73.700% * 45.95263 u) + (15.000% * 47.94795 u) + (11.300% * 49.94479 u)

Step 2: Calculate the individual contributions from each isotope:

= (0.737 * 45.95263) + (0.150 * 47.94795) + (0.113 * 49.94479)

Step 3: Add up the individual contributions:

= 33.84765431 + 7.1921925 + 5.64179347

Step 4: Sum up the contributions:

= 46.68164 u

Therefore, the average atomic mass of titanium on the given planet is approximately 46.68164 atomic mass units (u).

It's important to note that the calculation assumes the provided natural abundances are accurate and representative of the titanium isotopes on that planet.

There exist two non-isomorphic, unrooted trees with four vertices in part one if the tree has four vertices.

Draw the four vertices first. Next, create all feasible graphs with no edges (there is only one). Draw every conceivable graph with a single edge next (again, there is only one). Continue until the entire graph is drawn on four vertices. Sequences of zeros and ones of length 2n are used to encode non-isomorphic trees on n vertices. Such sequences are 22n=4n in number. In particular, there are two order 4-nonisomorphic groups: C4 and C2 C2 = D2 (read your notes; explain why this is the case).

Water, ice, acids, salts, plants, animals, and temperature fluctuations are all mechanical weathering agents. Erosion is the process by which the broken pieces of rock and mineral are moved away after a rock has been cracked.

Rocks that have holes or are porous (have holes) experience freeze-thaw weathering (allows water to pass through). In this case, mechanical weathering is evident. Different fissures in the rock allow water to enter (from rain, melting snow, or ice).

Weathering that releases pressure. Definition. expansion associated with the release of confining pressure when deeply buried rock is unroofed, leading to the development of fractures near the surface of solid rock. Typically, fractures spread along surfaces parallel to and near the surface.

Asexual reproduction is the mode of reproduction by which organisms generate offspring that are identical to the parent's without the fusion of gametes. Asexual reproduction is a type of reproduction in which the offspring is produced from a single parent.

The offspring created are clones of the parent plant, meaning they are identical to the parent.The new plant in Stephan’s mother cutting a twig from a rose bush and planting it in the soil depicts the process of asexual reproduction, which is the ability of a plant to reproduce without seeds.

The inorganic compound that is created by the removal or replacement of one, two, or all three hydrogen atoms in phosphoric acid and is commonly used in fertilizers and detergents, as well as a major cause of water pollution, is called "phosphate."

What do you mean by inorganic compound?

An inorganic compound is a chemical compound that does not contain carbon-hydrogen (C-H) bonds, which are the defining characteristic of organic compounds. Inorganic compounds can be composed of a variety of elements, including metals, non-metals, and metalloids.

The inorganic compound that is created by the removal or replacement of one, two, or all three hydrogen atoms in phosphoric acid and is commonly used in fertilizers and detergents, as well as a major cause of water pollution, is called "phosphate."

Phosphate compounds are essential nutrients for plant growth and are often added to fertilizers to improve soil fertility. However, when excess phosphate is added to water bodies, it can lead to eutrophication, a process where an excessive growth of algae and other aquatic plants occur, ultimately leading to oxygen depletion and harm to aquatic life.

Phosphates are also commonly used in detergents to aid in cleaning, but they can have similar negative impacts on water quality if they are not properly treated before being discharged into waterways. Therefore, regulations are in place to limit the amount of phosphate that can be added to detergents and other products in many countries to mitigate water pollution.

The correct answer is A. There are 6 carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms on the reactant side, and 6 carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms on the product side.

This is because of the law of conservation of matter, which states that matter cannot be created or destroyed by a chemical reaction. Therefore, the number of atoms of each element must remain the same on both sides of the reaction.

In this case, the number of carbon, hydrogen, and oxygen atoms must remain the same on both the reactant and product sides.
