Homework Answers
16) Cis-platin is Pt(NH3)Cl2 .
It molar mass is = atomic mass of [Pt + 2(MH3) + 2(Cl)]
=195. + 2(17.00) + 2(35.5) =300
thus OPTION B
17) The balanced equation is
4Fe(s) +3 O2(g) ---------> 2Fe2O3(s)
Thus the right option is E
18)The net ionic equation is
Cu+2 (aq) + S-2(aq) -----------> CuS(s) OPTION D
19)the balanced equation is
2C8H18 +25 O2 ----------> 16CO2 + 18H2O
OPTION E
