with 0.30 mL of cinnamaldehyde.
When 0.500 g solid sodium reacts with chlorine gas, a solid with a mass of 1.27 g is formed (sodium chloride). Based upon this information, what is the empirical formula of sodium chloride? Show your calculations.
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)
