The document discusses the reactions of metals with acids and their uses. It explains that metals are found naturally in ores and can be extracted. Certain metals like aluminum, steel, and iron have specific uses like in aircraft, cooking pots, etc. due to their properties. It also describes how most metals react with acids to produce salts and hydrogen gas. The reactivity of metals follows certain patterns that allow predictions of how a metal will react with acid.

2. METALS AND THEIR USES Objectives To know a range of metals that have specific uses. Metals are found in the Earth, sometimes as elements and sometimes in an ore. Make a list of keywords used in the learning objectives www.sciencetutors.zoomshare.com

4. A range of metals used for specific purposes. Look at these pictures and suggest the names of the metals used.

5. What metal is used for building aircrafts and why? www.sciencetutors.zoomshare.com

6. Why is aluminium or steel used in making cooking pots? Suggests why iron is not a good metal for making cooking pots www.sciencetutors.zoomshare.com
