What is the formula of the second compound if two oxides of a metal contain 27.6 percent and 30 percent of oxygen respectively and if the formula of the first compound is M3O4?
Formula of first oxide = M3O4 let mass of the metal be == x percentage of metal in M3O4 = (3x/ 3x+64) *100 but % age = (100-27.6) = 72.4 % so, (3x/ 3x+64)*100 = 72.4 or x = 56. in 2nd oxide, oxygen = 30%....so metal = 70% so, ratio :-- M : O 70/56 : 30/16 1.25 : 1.875 2 : 3 so, 2nd oxide = M2O3

How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
