Lithium is more reactive than calcium.
Explanation:
Lithium is more reactive than calcium. don't forget, lithium has one electron in its outer shell while calcium has . ... therefore less power is required to put off the the one electron from lithium than to remove the 2 from calcium, so lithium is more reactive.
Hope this helps..

Explanation:
We first find the solubility of the copper sulphate salt
Number of moles= 4.6 moles
Volume =1.75 L
Molarity= number of moles/ volume = 4.6/1.75= 2.6 molL-1
Hence, only 2.6 moles of Copper II sulphate dissolves in 1.75L of water. Hence 4.6 moles of copper II Sulphate dies not dissolve in 1.75 L of water.
