Explanation / Answer

13) An oxyacid containing two fewer oxygen atoms than the "-ic" acid would be the hydro...ous acid
14) Non Polar Molecule with polar Bond - CH4

15) Electronic Configuration of Sc3+ ion is 1s22s22p63s23p6

     Atomic number = 21, Number of electrons = 18, Charge = 21 -18 = +3

16) number of H atoms present in 27.6g of NH3 are 2.93 x 1024

17) The correct name for pure, aqueous HCN is hydrocyanic acid

18) the number of lithium atoms in 3.66 moles of lithium is 2.20 x 1024
