Aluminum dissolves in HCL according to the equation written below, whereas copper does not react with HCL: 2Al+6HCL ---> 2AlCl3 + 3H2 a 35 gram sample of copper-aluminum alloy is dropped into .750 L of 3M HCl, and the reaction above proceeds as far as possible. If the alloy contains 77.1% Al by mass, what volume of hydrogen gas would be produced at 22 degrees Celcius and 728 torr?
A large flask with a volume of 936mL is evacuated and found to have a mass of 134.66 g. it is then filled to a pressure of 0.967atm at 31 C with a gas of unknown molar mass and then reweighed to give a new mass of 135.91 g. what is the molar mass ..
What is the total mass of AlCl3 in this sample? b. How many moles of AlCl3 are in this sample?
What is the final temperature inside the vessel after combustion, assuming that the steel vessel has a mass of 13.695kg , the mixture of gases has an average molar heat capacity of 21J/(mol??C), and the heat capacity of steel is 0.499J/(g??C)?
