Use the unbalanced equation nh3+o2--> no+h2o to find the mole ratio between nh3 ad o2

The anwser is 4 moles of NH₃  react with 5 moles of O₂

Explanation:

To balance this equation we need to use stoichiometry, this tells us the mole ratio between reactants and products. It's based on the law of conservation of mass which states that mass cannot be destroyed and cannot be generated, its constant.

This means that in a chemical reaction we must have the same amount of mass in the reactants and products.

The number before a substance is its stoichiometric number, this tells us the amount of moles that substance that participate in the stoichiometric  reaction.

For example:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂0

In this equation 2 moles of C₂H₆ react with 7 moles of O₂ to produce 4 moles of CO₂ and 6 moles of H₂0.

So once the equation is balanced we can find the ratio between substances.

4NH₃ + 5O₂ → 4NO + 6H₂O

In this equation 4 moles of NH₃  react with 5 moles of O₂ to produce 4 moles of NO and 6 moles of H₂0.

alfred von schlieffen, german army chief of staff, was given instructions to devise a strategy that would be able to counter a joint attack. in december, 1905, he began circulating what later became known as the schlieffen plan. schlieffen argued that if war took place it was vital that france was speedily defeated.

thats a little if u want the answer just look it up on google thats what i do haha : )
