Saturated fats
These fats are derived from animal products such as meat, dairy and eggs. But they are also found
in some plantbased sources such as coconut, palm and palm kernel oils. These fats are solid at
room temperature. Saturated fats clog our arteries and directly raise total…

Unstaurated oils contain double bond molecules which are liquids at room temperature.
The unsaturated molecules have lowish melting points. To increase the melting points
of these molecules we have to harden them in a reaction called hydrogenation.
This is done by reacting the oil with hydrogen in the presence of…

Alkenes burn with a nonsmoky flame TRUE contain double bonds, so
they react with the oxygen quickly.







































Burning Fuels

Hydrocarbons burn in air to produce carbon dioxide and water.
Propane + oxygen carbon dioxide + Water
All fuels produce carbon dioxide and water when they burn in air, however as…

When we burn fuels in air, the Sulfur reacts with the oxygen to make sulphur dioxide which is the
main cause of acid rain.
In a car engine, if their isn't enough oxygen for the Carbon to react with, a poisonous gas is
produced Carbon Monoxide CO .(This is also…

d) Acid rain: rain containing acids which have been formed from the result of industrial gas
emissions (especially sulphur dioxide and Nitrogen Oxides) reacting with water.

2. A molecule of carbon monoxide requires another atom of oxygen if it is to become a
molecule of carbon dioxide. How does a…
