According to the following balanced equation, 2 formula units of iron (III) oxide (Fe2O3) can be formed by reacting 4 atoms of iron (Fe) with 3 molecules of oxygen gas (O2). If 12 atoms of iron are reacted with 6 molecules of oxygen gas, which is the limiting reactant and how many atoms or molecules will be left over?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
