Some commercial drain cleaners contain two components: sodium hydroxide and aluminum powder and undergo the following reaction:
2NaOH(aq) + 2Al(s) + 6H2O(l) → 2NaAl(OH)4 (aq) + 3H2(g) in the presence of water (for H2, the van der Waals constants are a=0.244 atm*L2/mol2 and b=.0266 L/mol). Assuming the reaction is done in a 2.0 L container at 300 K:
a) What is the pressure of H2 (assuming H2 is an ideal gas) when 6.0 g of Al is treated with excess NaOH
b) What is the pressure of H2 (assuming H2 is a nonideal/real gas) when 6.0 g of Al is treated with excess NaOH

6. Commercial drain cleaners sometimes contain a mixture of aluminum powder and NaOH. When the mix is poured down a clogged drain, the following occurs: 2 NaOH(aq) + 2Al(s) + 6H2O(0) ► 2NaAl(OH)/(aq) + 3H2(g) + Heat Heat melts grease and gas breaks up the clogs. What volume of hydrogen is formed at 1.00 atm and 21.0°C when 5.00 g of Al are treated with excess NaOH?
