    • using ideal gas with chemical reactions u can determine volumes, pressures, temperatures, and moles of different substances
    • ex: aluminum corrodes in HCL and releases hydrogen gas. if 15.0 g of Al id allowed to react with HCL, what volume of Hydrogen gas will be produced at 25°C and 744 mm Hg
    • step one: equation
    • Al + HCl —> AlCl + H2
    • step 2: ionic bonds
    • Al + HCl —> AlCl3 + H2
    • step 3: balance
    • 2Al + 6HCL —> 2AlCl3 + 3H2 
    • step 4: find the mols of Hydrogen gas 
    • 0.833 mol H2
    • step 5:
    • use ur ideal gas law
    • 20.8 L
