Determine the limiting reactant (LR) and the mass (in g) of nitrogen that can be formed from 50.0 g N2O4 and 45.0 g N2H4. Some possibly useful molar masses are as follows: N2O4 = 92.02 g/mol, N2H4 = 32.05 g/mol.
 
  N2O4(l) + 2 N2H4(l)  3 N2(g) + 4 H2O(g) A) LR = N2H4, 59.0 g N2 formed
  B) LR = N2O4, 105 g N2 formed
  C) LR = N2O4, 45.7 g N2 formed
  D) LR = N2H4, 13.3 g N2 formed
  E) No LR, 45.0 g N2 formed

Question 2

The HCO3- ion is called ________.
 
  A) carbide
  B) bicarbonate
  C) carbonate
  D) carboxide
