Consider the equation of aluminum with sulfuric acid as shown below:
2A1 (s) + 3H2SO4 (aq) → Al2(SO4)3 (aq) + 3H2 (g)
a) Classify the reaction.
b) How many moles of H2S04 are required to completely react with 8.00 mole Al?
c) How many grams of H2 gas will be formed if 5.15 grams of aluminum reacts with excess sulfuric acid?
d) If we begin with 215 grams of aluminum and 275 grams of sulfuric acid, what would be the aluminum sulfate theoretical yield of
the reaction?
e) Calculate number of molecules of aluminum sulfate from the theoretical yield obtained from part d).
Use units, significant figures correctly. For very large or small numbers, be sure to express responses in scientific notation. Show your work neatly.
