Sulfur trioxide dissolves in water to make sulfuric acid, H2O4. Write a balanced chemical equation and determine the mass of sulfuric acid that can be produced from the reaction of 18.0ml of water (d = 1.00g/mL) and 8.6g of SO3
3. You start with a 3.865 g sample of a salt which has the formula Cox Cly · zH₂O, where x, y, and z are unknown. After gently heating the salt (as you did in lab with a similar compound), the mass decreased to 2.108 g. The remaining salt was then dissolved in water to form a clear solution. After adding an excess of aluminum metal, the solution fizzed, and a new blueish precipitate formed. After collecting and drying the blue precipitate, its mass was measured to be 0.957 g. Determine the empirical formula of the original compound.
