Based upon the strength of the intermolecular attraction and the relative molecular masses, rank the following in order of increasing boiling point from lowest to highest. For example, if B is lowest, A is the next higher, C is next, and D is highest, enter BACD. A) HBr B) HF C) HCl D) HI 

The metal used to recover copper from a solution of copper sulphate isA.NaB.AgC.HgD.Fe

1. A 2.00 L container with 4.05g of ethane gas (C2H6) is placed in a constanttemperature bath. The pressure in the container stabilizes to 1.46 atm. What isthe temperature (K) of the gas?2. Calculate the volume (L) of 525g N2 at 787 torr and 25oC.3. Some commercial drain cleaners contain two components: sodium hydroxide andaluminum powder. When the mixture is poured down a clogged drain, thefollowing reaction occurs:2NaOH(aq) + 2Al(s) + 6H2O(l)  2NaAl(OH)4 (aq) + 3H2(g)The heat generated in this reaction helps to melt away grease and the hydrogengas released stirs up the solids clogging the drain. Calculate the volume of H2formed at 25oC and 1.02 atm if 3.72 g of Al is treated with excess NaOH andH2O.
