What is the molar solubility of AgCl in a 0.050 M NaCl solution? The Ksp of AgCl is 1.6 x 10-10. (Assume that the contribution of [Cl-] from AgCl is negligible relative to the [Cl-] from NaCl)

Answer:

answering this for points! Sorry! but its probably A OR C

Explanation:

Answer:

6.27 X 10^26 atoms

Explanation:

Write down the formula:

number of moles = mass/Ar    (Ar is atomic mass)

Ar of carbon = 12

mass = 12.5kg or 12500g

Substitue these values into the formula:

number of moles = 12,500g / 12 = 3125/3 or 1041.6

Convert this to atoms:

1 mole = 6.022 X 10^23 atoms

So, 1041.6 moles = 6.27 X 10^26 atoms

Answer:

its B

Explanation:

Answer:

the the answer iss ( true )

0.026 moles is the right answer.

We have that for the Question "How many moles of xenon gas are necessary to exert a 0.64atm pressure in an 8.5L container at 300.0K?" it can be said that  moles of xenon gas is

n=0.22moles

From the question we are told

How many moles of xenon gas are necessary to exert a 0.64atm pressure in an 8.5L container at 300.0K?

Generally the equation for the ideal gas is mathematically given as

[tex]n=\frac{Pv}{RT}\\\\n=\frac{0.64*8.5}{0.08206*300}[/tex]

n=0.22moles

Therefore

How many moles of xenon gas are necessary to exert a 0.64atm pressure in an 8.5L container at 300.0K is

n=0.22moles

Answer:

Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2

Explanation:

On the left you have an original balance of Ca - 1, N - 2, O - 6, Na - 1, and Cl - 2, and on the right you have a balance of Ca - 1, N - 1, O - 3, Na - 1, Cl - 2.

Ca - 1 Ca - 1

N - 2 N - 1

O - 6 O - 3

Na - 1 Na - 1

Cl - 1 Cl - 2

In order to balance these, you'll have to make both sides equal. To get the N on the right to be equal to the N on the left, you'll have to multiply NaNO3 by 2, thus making it 2NaNO3. By doing this, you will offset the balance of both Na and O.

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 1 Na - 2

Cl - 1 Cl - 2

To balance the rest of the equation, you'll have to multiply both Na and Cl by 2. This will change NaCl to 2NaCl, making the balance look like this:

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 2 Na - 2

Cl - 2 Cl - 2

You will now be left with your final equation Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2.

Sterilizing the water rarely used in treating the sewage water is described below in details.

Explanation:

Sterilization is the application of a chemical or physical system to eradicate all microorganisms, concluding comprehensive amounts of bacterial content. Heat treatment is the most relevant approach for the sterilization of waste-water that accommodates large levels of masses. well now sterilizing the water is un-usually practiced in managing the sewage water.

Answer:

Explanation:

In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.

Answer:

A. electrons must be parts of the atoms of all elements

Answer:

3.97mL of 1.00M HCl must be added

Explanation:

The buffer of ammonia and ammonium ion follows the equation:

pH = pKa + log [NH₃] / [NH₄⁺] (1)

Where pH is the pH we want to obtain: 10.00

pKa is the pKa of the buffer: 9.25

[NH₃] could be taken as moles of ammonia

And NH₄⁺ moles of ammonium ion

When NH₃ reacts with HCl:

NH₃ + HCl → NH₄⁺ + Cl⁻

NH₄⁺ is produced. That means moles of ammonia are Initial moles of ammonia - Moles of HCl added

Moles of HCl added = Moles of ammonium ion

The total moles of the buffer are:

0.100L * (0.263mol / L) = 0.0263moles = [NH₄⁺] + [NH₃] (2)

Rewriting (1):

10.00 = 9.25 + log [NH₃] / [NH₄⁺]

0.75 = log [NH₃] / [NH₄⁺]

Replacing (2) in (1):

0.75 = log 0.0263 -  [NH₄⁺] / [NH₄⁺]

5.6234 = 0.0263 -  [NH₄⁺] / [NH₄⁺]

5.6234[NH₄⁺] = 0.0263 - [NH₄⁺]

6.6234[NH₄⁺] = 0.0263

[NH₄⁺] = 0.00397 moles = Moles HCl

To obtain these moles we must add:

0.00397 moles HCl * (1L / mol) = 0.00397L =

3.97mL of 1.00M HCl must be added

Answer:

The dispersed particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas. Because the dispersed particles of a colloid are not as large as those of a suspension, they do not settle out upon standing.

Answer:

A nanowire is a nanostructure, with the diameter of the order of a nanometre (10−9 meters). It can also be defined as the ratio of the length to width being greater than 1000. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important—which coined the term "quantum wires". Many different types of nanowires exist, including superconducting (e.g. YBCO[1]), metallic (e.g. Ni, Pt, Au, Ag), semiconducting (e.g. silicon nanowires (SiNWs), InP, GaN) and insulating (e.g. SiO2, TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9−xIx).
