The table given below shows the reactions of metals with the solutions of metal salts,
Reaction of Metal X with: Reaction of Metal Y with: Reaction of Metal Z with
X sulphate → No reaction X sulphate → No reaction X sulphate → No reaction
Y sulphate → Displaces Y Y sulphate → No reaction Y sulphate → Displaces Y
Z sulphate → Displaces Z Z sulphate → No reaction Z sulphate → No reaction
a) On the basis of your observation of the data given above, arrange the metals X, Y,
and Z in order of increasing reactivity and justify your answer.
b) Will copper react with a salt solution of zinc chloride? Justify your answer.

Answer:
The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. The ends of the bones are covered with cartilage. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock. The bones are held together with ligaments that form the joint capsule.
