Re: Limiting reagents

You can only have one limiting reactant because it limits what product can be produced, so it is not possible to have more than one.

Re: What do the coefficients/subscripts represent [ENDORSED]

The coefficient is called the stoichiometric coefficient and it is what you can change to balance equations, but it also tells you how many moles of a molecule you have. In this example, 4 is the stoichiometric coefficient, so you would have 4 moles.
