Thanks for the answer,can the ratio of the second one be H3NSO3:KOH=2:1?that's what I've found out...by the way i can t still understand the first one :)

well thank you for the answer.Regarding the first one i wrote the formula as:5Mg+O2+2N2=2MgO+Mg3N2 and if 3,6g is Mg and 5,7 is MgO+Mg3N2 i did 5,7-3,6=2,1 to find out the mass of O2+N2(maybe)...but i don t know hwo to find the masses separately. Regarding the second one,i can't understad the...

1)When Mg is burned in air,a mixture of MgO and Mg3N2 is produced.If 3,6g of Mg produces 5,7g of mixture,what is the percentage by mass of each compound in the mixture? 2)A solution of an acid having the formula H3NSO3 is prepared by dissolving 9,7g in water and making up the solution to...
