Solid iron (III) oxide reacts with gaseous carbon monoxide to produce solid elemental iron and gaseous carbon dioxide. If 0.550g of iron (iii) oxide reacts with 0.250g of carbon monoxide, how much solid elemental iron will be produced (in grams). Determine which reagent is in excess, and how much will be left over (in grams).

I'm sorry i cant you if you don't list the elements : (

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
