NH3 = 2, Nitrogen & Hydrogen, 1 & 3, 4
H3CO3 = 3, Hydrogen & Carbon & Oxygen, 3 & 1 & 3, 7
C12H22O12 = 3, Hydrogen & Carbon & Oxygen, 12 & 22 & 12, 46
MgSO4 = 3, Magnesium & Sulfur & Oxygen, 1 & 1 & 4, 6
NaOH = 3, Sodium & Oxygen & Hydrogen, 1 & 1 & 1, 3
H2O2 = 2, Hydrogen & Oxygen, 2 & 2, 4
Fe2O3 = 2, Iron & Oxygen, 2 & 3, 5
Na2HCO3 = 4, Sodium & Hydrogen & Carbon & Oxygen, 2 & 1 & 1 & 3, 7
There that took a while. Pretty sure thats what the sheet wants you to do
