Aluminum reacts with oxygen to produce aluminum oxide which can be used as an adsorbent, desiccant or catalyst for organic reactions.
4Al(s) + 3O2(g) --> 2Al2O3(s)
A mixture of 82.49 g of aluminum (MM = 26.98 g/mol) and 117.65 g of oxygen (MM = 32.00 g/mol) is allowed to react. Identify the limiting reactant and determine the mass of the excess reactant present in the vessel when the reaction is complete.
A balloon filled with H2(g) at STP has a volume of 2.24 .What is the final gas volume if 0.10 mol He(g) is added to the balloon and the temperature is then raised to 92.0 celsius while the pressure and amount of gas are held constant?
Determine what would be the final temperature if thirty grams of Al at 95 degrees Celsius are added to 100 grams of H 2 O at 25 degrees Celsius?
an optically pure compound was diluted to 200.0 mL with water and placed in a polarimeter tube 10.0 cm long. The measured rotation was -2.53° at 25 °C. Calculate the specific rotation of the compound.
Describe how you would prepare 150.0 mL of a pH = 5.00 buffer solution from a solution of 0.200-M aniline, C6H5NH2, a weak base
