Chemistry Revision
10 MARK QUESTIONS
1. This question is about rocks and metals. Iron is the second most
abundant metal in the earth’s crust, and is widely used all over the
world, due to its properties and ability to produce steel as an alloy.
Describe the production of steels including the following in
chronological order:
• Extraction of Iron from its ore
• About the common impurities
• Elements combined to produce steel
• Different % of elements for different steels
(10)
2. This question is about salt making. There are four types of ways to
produce salts. Choose one salt production reaction to a produce a
particular salt, for example sodium chloride etc. Write the complete
method to produce this salt, including purification of the salt. Ensure
you include a balanced symbol equation for the reaction, and a general
equation for the type of salt production reaction you have chosen, e.g.
acid + ………….. -> salt + ……………… etc.
