calculate the amount in moles of oxygen that is needed to react with 2.4 mole of ammonia to produce poisonous hydrogen cyanide. The chemical equation is 2NH2+3O2+2CH4=2HCN+6H20. THE ANSWER IS 3.6 MOL OF O2. i need to see the equation we would use

Question

calculate the amount in moles of oxygen that is needed to react with 2.4 mole of ammonia to produce poisonous hydrogen cyanide. The chemical equation is 2NH2+3O2+2CH4=>2HCN+6H20. THE ANSWER IS 3.6 MOL OF O2. i need to see the equation we would use

anonymous · Answer

you don't use an equation you just use the ratios given by the balanced chemical equation. You can do this... $$\frac{ 2.4MolNH2 }{ 1 }*\frac{ 3MolO2 }{ 2MolNh2 }$$ the Mol Nh2 will cancel out and you will get 3.6 mol O2
