Answer:

True

Explanation:

The following two isotopes of Uranium which are prominently used in a nuclear chain reaction.

a) Uranium-233

b) Uranium-235

Uranium 235 consists of 92 protons and 143 neutrons. When an excited electron hits a Uranium atom, it splits into two smaller atoms and release heat energy under the process of fission.

There is another isotope of Uranium i.e Uranium -238, but it does not break easily and hence is less preferred for a nuclear reaction.

Thus, it can be said that the statement "lsotopes of uranium are used as nuclear fuel in power plants." is true.

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
