Predict what you would expect to observe when each of the following substances is mixed with NaI/acetone. Would you expect a difference in their relative rates of reaction? Explain
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.
Calculate the pressures in the flask in parts a and b (in torr) if the atmospheric pressure were instead 675 torr.
