Question:

heinrich adds lots of oxygen gas to some iron to produce 110g. of iron (III) oxide. How many grams of iron did?

heinrich adds lots of oxygen gas to some iron to produce 110g. of iron (III) oxide. How many grams of iron did she start with?

Answer:

I choose this could help. including tension to the oxygen make a compressed oxygen widely used to be pressurized oxygen. including tension to oxygen make it much less reactive or stable. including a compressed oxygen to the iron(III)oxide only make the yield under the reaction of iron(III)oxide with none compressed oxygen. occasion 2 Fe^ +3 + O^ -2 (not compressed) Fe2O3 yield approximately 2g (it particularly is only an occasion) in 2 Fe^ +3 + O^ -2 (utilising compressed) Fe2O3 yield in basic terms 1g (it particularly is only an occasion) see utilising a robust oxygen low the quantity of yield of iron(III)oxide.
Iron Fe, atomic mass 56 Iron(III)oxide Fe2O3, molecular weight 160 110g / 160 * 56 * 2 77g Iron at the start.
