Question 7
Using Basic proportionality theorem, prove that a line drawn through the mid-points of one side of a triangle parallel to another side bisects the third side.
A more reactive metal (one that forms positive ions more easily) can displace a less reactive metal from a compound. This is called a displacement reaction. A metal can only displace another metal from a compound if it is located above it in the reactivity series
