Compare the mineral halite (NaCl, hardness of 2.5) to diamond which is pure carbon chemically bonded to itself in a network. Are the mineral's chemical bonds covalent, polar covalent, or ionic? Which mineral is harder?
On Mohs scale, isn't diamond assigned a $10$ on the basis of hardness? Halite is almost a purely ionic material.

Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's position on the periodic table? Do not conduct calculations.
Something worth knowing about deciding between nonpolar and polar is that only two of the same element can form an ideally nonpolar bond. With this in mind, the $"Br"-"Br"$...

What is the reaction between $CuCl_2$, and aluminum metal to give copper metal and $AlCl_3$?
$Al rarr Al^(3+) + 3e^-$; oxidation. $CuCl_2(aq) +2e^(-) rarr Cu(s)darr + 2Cl^-$; reduction. We cross-mulitply to remove the electrons. $3CuCl_2(aq) +2Al(s) rarr 2AlCl_3(aq) + 3Cu(s)darr$ A sheet of aluminum place...
