There are many chemical pollutants in the air which may be carried by wind across the globe, and be dissolved in the rain or bodies of water used to irrigate ‘organic’ crops. Everything has chemical compounds in it. |

1.
When the polystyrene comes into contact with acetone, it acts as a molecular lubricant allowing the polymer chains to slide around each other hence, the styrofoam becomes soft and releases the air bubbles, consequently resulting in a denser polystyrene solid. |
|
2.
a. It does not have the required strength to resist a cut |
|
3.
No, paper does not stretch. |
|
4.
a. resistant to corrosion, durable, non-toxic, inert, semi-permeable (allowing essential materials to diffuse allowing for material transport). |

They can differ in number of neutrons (forming isotopes), and in the number of electrons. Carbon vs. Uranium atoms |
|
2.
The symbol N represents the element nitrogen and stands for the naturally occurring mixture of all isotopes, hence symbols 15N and 14N are isotopes of the same element – consequently they have different mass numbers of 15 and 14 respectively. |

1.
High energy impact, which relates to high cost of operation, as well as increased burning of fossil fuels. Making it less competitively priced that other alternatives. |
|
2.
Water soluble vitamins are polar compounds, while fat soluble vitamins are non polar. |

(a) Dryers are major consumers of electricity in the home. Hence, hanging laundry out to dry reduces the amount of electricity consumed, which in turn reduces reduces the burning of fossil fuels, consequently reducing SOx and NOx and acid rain. (b) Reducing production of SOx and NOx. (c) Dishwashers are major consumers of electricity in the home. Hence, not using the dishwasher reduces reduces the burning of fossil fuels, consequently reducing SOx and NOx and acid rain. (d) Reduce heat loss, hence reducing the amount of electricity consumed, which in turn reduces reduces the burning of fossil fuels, consequently reducing SOx and NOx and acid rain. (e) Reducing Air and sea transportation for produce by buying local produce reduces the burning of fossil fuels, consequently reducing SOx and NOx and acid rain. |

4.
Coal fired electricity unitility plans produce hight amounts of SOx , which will be converted to Sulphuric acid when in contact with water vapour in the atmosphere and remains suspended. This reflects lights hence causing poor visibility and acid rain. pH about 4.3. |

1.
a. Exothermic: combustion gives off heat |
|
2.
Energy for bond forming is much greater than energy for bond breaking. |
|
3.
Temperature is like a measurement. Heat is the total energy of molecular motion. |
|
4.
