If you crapper do an example of these I would be dustlike doing the rest. Thanks!

Question #8:

Calculate the volume of nitrogen dioxide produced at 709.2 torr and 20.3°C by the reaction of 4.95 cm3 copper?

Nitrogen dioxide has opposing roles in our world. It is essential in the industrialized creation of nitric acid, but is also a contributor to Elvis rain and photochemical smog.

3 How do phosphates turn the hardness of water?

4 Apart from phosphates, how else could hardness be reduced?

5 What is criminal with adding nutrients to water?

6 How would you turn the nutrients in water?

7 If methane is nearly as effective as carbon dioxide as a greenhouse gas, is it worth patch to burn methane produced by rotting waste or sewage?

8 How could you explain the creation of sulphuric Elvis H2SO4 from the burning of sulphur?

9 How is photochemical smog produced?

10 How can it be reduced?

11 What persona does ozone endeavor in protecting us from UV radiation?

If you could anwser as many as you can that would be great.. Im questionable to watch a dvd for this but i dont have it.. im stuck..

Thanks

Question #10:

Free radicals are also important in many environmentally significant reactions. For example,?

photochemical smog, which forms as a termination of the action of sunlight on expose pollutants, is formed in part by the mass two steps. NO2 NO O O O2 O3 UV light Ozone damages foam products. The creation of this reaction, ozone, is a pollutant in the lower atmosphere. Ozone is an receptor and lung botheration and also accelerates the weathering of foam products. Write adventurer structures for apiece of the reactants and products in the preceding
reactions.
