The solubility product constant, Ksp, for Ag2SO4 is 1.2 x 10-5 at 25o C. Find [Ag ] and [SO4 2-] after 0.755 g of AgNO3 are adde

d to a 500.0 mL saturated solution of Ag2SO4 and equilibrium is established. Assume that the total volume of the solution remains the same and the final temperate is 25o C.

Answer:

[Ag+] = 0.032 M

[SO42-] = 0.0116 M

Explanation:

  • AgNO3 ↔       Ag+      +       NO3-

      8.89E-3 M   8.89E-3 M      8.89E-3 M

∴ mass AgNO3 = 0.755 g

∴ mm AgNO3 = 169.87 g/mol

⇒ mol AgNO3 = (0.755 g)(mol /169.87 g) = 4.44 E-3 mol

⇒ M AgNO3 = 4.44 E-3 mol/0.500 L = 8.89 E-3 M

  • Ag2SO4 ↔        2Ag+         +     SO42-

           S               2S + 8.89E-3             S

⇒ 1.2 E-5 = (2S + 8.89E-3)²(S)

⇒ 1.2 E-5 = (4S² + 0.036S + 7.903 E-5)(S)

⇒ 1.2 E-5 = 4S³ + 0.036S² + 7.903 E-5S

⇒ S³ + 9 E-3S² + 1.976 E-5S - 3 E-6 = 0

⇒ S = 0.0116 M

⇒ [Ag+] = 2(0.0116) + 8.89 E-3 = 0.032 M

⇒ [SO42-] = S = 0.0116 M

Once you have completed your research, write a summary about what characterizes science and its methods. Identify a question tha
Yuki888 [10]

Answer:

- Scientific question: does life exist on other planets?

- Non-scientific question: there are aliens that look like people?  

Explanation:

A scientific question is a coherent question that can be used to develop a scientific hypothesis. Thus, a scientific question must be testable, verifiable, measurable and relevant to the topic of study. In the scientific method, the hypothesis is subsequently tested by experimental or observational procedures, where the results can be used to understand some particular aspect of the real world. On the other hand, a non-scientific question is a light conjecture which cannot be proved by using the scientific method.

What is the potential energy of a 2-kg vase sitting on a table with a height of 1<br> meter?
lisov135 [29]

"20 J" is the "Potential Energy" of "vase" on the table.  

<u>Explanation</u>:

The body possess some energy according to the position of the object that is the when an object is placed at a height it stores some energy it is called "Potential Energy".

Formula used to calculate the "Potential Energy" is m\times g \times h

Where, "m" is mass of vase is given that 2 kg, "g" is acceleration due to gravity is 10 m/s^2 and "h" is height of the object where it placed is 1 m.

Substitute the given values in the formula,

Potential energy of the vase = 2\times10\times1

Potential energy of the vase = 20 J
