The equilibrium constant shows the extent of dissolution of a substance in solution. The molar solubility of the compound here is 1.2 * 10^-8 M.

The solubility product is the equilibrium constant that shows the extent to which a substnace is dissolved in soution.

Now let us set up the ICE table as shown;

               Cr(OH)3 (s) <-> Cr^3+ (aq) + 3OH^- (aq)

E                                          x                   3x

Ksp = [Cr^3+] [OH^- ]^3

6.3x10^-31 = [x] [3x]^3

6.3x10^-31 = 27x^4

x = 4√6.3x10^-31 /27

Answer:

The Lewis structure for XeF4 has a total of 36 valence electrons. When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell). We also need to check to make sure we only used the number of available valence electrons we calculated earlier (no more, no less).

Explanation:

From the ideal gas law, the pressure of the gas is 106 kPa.

First we must obtain the number of moles of the gas;

Number of moles = mass/molar mass

Molar mass of fluorine gas = 38 g/mol

Number of moles of F2 = 6.40 g/38 g/mol = 0.168 moles

Using the ideal gas equation;

PV = nRT

P = ?

V = 3.90 L

n =  0.168 moles

T = 25.0 ⁰C + 273 = 296 K

R = 8.314  kPa L K-1 mol-1

Substituting values;

P = nRT/V

P =  0.168 moles × 8.314  kPa L K-1 mol-1 ×  296 K/3.90 L

P = 106 kPa

The pressure of the vessel at a temperature of 25 °C is 106.73 KPa

We'll begin by calculating the number of mole of fluorine gas. This can be obtained as follow:

Mass of F₂ = 6.40 g

Molar mass of F₂ = 19 × 2 = 38 g/mol

Mole = mass / molar mass

Mole of F₂ = 6.40 / 38

Finally, we shall determine the pressure. This can be obtained as follow:

Volume (V) = 3.90 L

Temperature (T) =  25.0 °C = 25 + 273 = 298 K

Mole of F₂ (n) = 0.168 mole

Gas constant (R) = 8.314 L.KPa/Kmol

PV = nRT

P × 3.9 = 0.168 × 8.314 × 298

P × 3.9 = 416.232096

Divide both side by 3.90

P = 416.232096 / 3.90

Therefore, the pressure of the vessel is 106.73 KPa

300 g of LiClO₄ produce 5.64 moles of O₂, which is equivalent to 136 L of O₂ at 101.5 kPa and 21 °C.

Let's consider the following balanced equation.

LiClO₄(s) ⇒ 2 O₂(g) + LiCl(s)

We can calculate the moles of O₂ produced from 300 g of LiClO₄ using the following relationships.

[tex]300 g LiClO_4 \times \frac{1molLiClO_4}{106.39gLiClO_4} \times \frac{2molO_2}{1molLiClO_4} = 5.64molO_2[/tex]

Then, we will convert 101.5 kPa to atm using the conversion factor 1 atm = 101.325 kPa.

[tex]101.5 kPa \times \frac{1 atm}{101.325kPa} = 1.002atm[/tex]

Next, we will convert 21 °C to Kelvin using the following expression.

[tex]K = \° C + 273.15 = 21\° C + 273.15 = 294 K[/tex]

Finally, we will calculate the volume occupied by 5.64 moles of oxygen using the ideal gas equation.

[tex]P \times V = n \times R \times T\\\\V = \frac{n \times R \times T}{P} = \frac{5.64 mol \times (\frac{0.082atm.L}{mol.K} ) \times 294K}{1.002atm} = 136 L[/tex]

300 g of LiClO₄ produce 5.64 moles of O₂, which is equivalent to 136 L of O₂ at 101.5 kPa and 21 °C.

Aria speed during scuba diving was 0.15 m/s.

Speed is the ratio of the distance travelled to the time taken. Speed is given by:

Speed = distance / time

Given that the distance travelled was 36 meters and the time was 4 minutes, hence:

Time = 4 minutes × 60 seconds per minute = 240 seconds

Speed = 36 m / 240 s

Speed = 0.15 m/s

Therefore Aria speed during scuba diving was 0.15 m/s.

Answer:

For the CH3- structure use the periodic table to find the total number of valence electrons for the CH3- molecule. Once we know how many valence electrons there are in CH3- we can distribute them around the central atom with the goal of filling the outer shells of each atom.

In the Lewis structure of CH3- structure there are a total of 14 valence electrons.

Also note that you should put the CH3- Lewis structure in brackets with as 1- on the outside to show that it is an ion with a negative one charge.

----- Steps to Write Lewis Structure for compounds like CH3- -----

1. Find the total valence electrons for the CH3- molecule.

2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside.

3. Put two electrons between atoms to form a chemical bond.

4. Complete octets on outside atoms.

5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds.

Lewis Structures, also called Electron Dot Structures, are important to learn because they help us understand how atoms and electrons are arranged in a molecule. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).

Explanation:

Volume is how much of a substance something can hold!

Hope this helped, have a nice day! :)

The word that completes the sentence is "volume."The volume of a bottle refers to how much liquid it can hold, typically measured in liters or milliliters.

Knowing the volume of a bottle is important when you need to measure out or store a certain amount of liquid. Different types of bottles have different capacities, so it's important to check the label or specifications to determine the right size for your needs.

Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.

Thus, the word that completes the sentence is "volume."

A. The neutrons and electrons are in the wrong place.

Explanation:

The atom's nucleus contains both protons and neutrons, whilst the electrons are arranged in shells around the nucleus.

The bond in NO3- ion is polar covalent and oxygen pulls the electrons.

A polar covalent bond is formed when there is a significant difference in electronegativity between covalently bonded atoms.

Such bonds are said to be polar covalent with the electron density tilted towards one of the bonding atoms.

In NO3-, Nitrogen and oxygen have an electronegativity difference of 0.5, so the bond is polar covalent, with oxygen pulling the electrons toward it.

The answer is A, Nitrogen and oxygen have an electronegativity of 0.5, so the bond is polar covalent, with oxygen pulling the electrons toward it.

Electronegativity is defined as, a value that describes the relative strength with which an atom of an element attracts electrons to itself in a chemical bond. Moreover, electronegativity can be used to define a bond.

A electronegativity of 0.5-1.7 is determined to be a polar covalent bond, thus the bonds in nitrate is polar covalent.

We know that electronegativity increases on the periodic table across a period, but decreases down a group. Thus, oxygen has a greater electronegativity than nitrogen.
