a sample of aluminum weighgin 1.500g reacted completely with an excess of aqueous HCl to produce 7.431 g aluminum chloridei need the percent AL in the aluminum chloride durign the reactionand part b- the percent of Cl in the aluminum chloride
2Al + 6HCl - 2AlCl3 + 3H2 atomic mass Al 26.98gm/mol molecular mass AlCl3 133.3gm/mol 1.5gm/26.98gm/mol 0.056 moles Al used This will yield 0.056 moles of AlCl37.431gm/133.3gm/mol 0.056 mol, as predictedThe % Al 26.98/133.3 x 100 20.2 % Al, leaving 79.8 % Cl
An Aluminum ion, Al3+ has:? How many protons Electrons ? 13 protons as no 13 in the periodic table Al ATOMS only have 13 electrons, but three are lost to give a full outer orbit and the Al3+ ion 13 - 3 10 electrons
