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>

Compare the recycling of metal in paper. How are they similar? How are they different?
liubo4ka [24]

Most of the metal we throw away at home comes from food and drink cans and aerosols. Typically food cans are made from steel, which can be melted down and turned into new food cans. Drinks cans are generally thinner and lighter and made from aluminum, which can also be recycled very easily. Mining aluminum is a very energy-intensive and environmentally harmful process. That's why waste aluminum cans have a relatively high value and why recycling them is such a good thing to do.

One problem with recycling paper is that not all paper is the <em>same</em>. White office printer paper is made of much higher quality raw material than the paper towels you'll find in a factory washroom. The higher the quality of paper waste, the better the quality of recycled products it can be used to make. So high-grade white paper collected from offices can be used to make more high-grade white recycled paper. But a mixture of old newspapers, office paper, junk mail, and cardboard can generally be used only to make lower-grade paper products such as "newsprint" (the low-grade paper on which newspapers are printed). Corrugated cardboard (which is held together with glue) is harder to recycle than the thin cardboard used to package groceries.

In conclusion, metals are almost all the same. There are a variety of different papers, (paper towel, cardboard, etc) so it is very hard to recycle that if they are all different.

Hope this helped!
