a.[1]
Name the gas given off in the trough containing lithium.
b.[1]
Name the other product formed when lithium reacts with water.
c.[1]
Use the figure to place the three metals in order of reactivity, starting with the most reactive.
d.[1]
The student concludes that copper is the least reactive of all metals. Give one reason why the student cannot be sure of this conclusion.
