Answer:
To find the number of moles of hydrogen produced from 10.0 moles of aluminum, you need to balance the equation for the reaction between aluminum and sulfuric acid.
Step 1: Balance the equation:
2Al + 3H2SO4 --> Al2(SO4)3+3H2
Step 2: Determine the stoichiometric ratio of moles of hydrogen produced per mole of aluminum:
From the balanced equation, 3 moles of hydrogen are produced for every 2 moles of aluminum.
Step 3: Calculate the number of moles of hydrogen produced:
If you start with 10.0 moles of aluminum, then the number of moles of hydrogen produced would be 3 * (10.0 moles of Al / 2 moles of Al) = 15 moles of hydrogen.
