If 11.4 kilograms of Al2O3(s), 51.4 kilograms of NaOH(l), and 51.4 kilograms of HF(g) react completely, how many kilograms of cryolite will be produced?
y-Fe2o3 and Fe3o4 are supposed to be face centred cube however when I do the calculations based on there peaks on the x-ray spectra the idex whcih are the hkl are all possibilties odd and even so thats primitive? or am I doing something wrong?
