What volume of chlorine gas, measured at STP, is necessary for the complete reaction of 5.02 g of aluminum?
Molar mass: Al = 26.98 g/mol, Cl2 = 70.90 g/mol, AlCl3 = 133.34 g/mol
2 Al(s) + 3 Cl2(g) --> 2 AlCl3(s)
please help and no scamming thank you

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
