PLEASE HELP I WILL GIVE BRAINLIEST In the compound iron (III) oxide, also known as rust, the mass ratio of iron to oxygen is 7.0:3.0. A 33-g sample of a compound composed of iron and oxygen contains 10. g of oxygen. Is the sample iron (III) oxide? Explain your answer. (Hint: Turn the whole number ratios into unit ratios.) Show your work.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
