Limiting Reactants

Postby Bilal Pandit 1J » Sun Oct 06, 2019 12:11 am

Would we ever have to calculate the amount of remaining reactant in a calculation (how much of the reactant that isnt limiting is left)

If the question asks for it, then you should subtract the grams of the amount of the excess reactant from the grams of the limiting reactant already calculated.

Yes, this type of question is fair game and you could expect to see it on an exam

Yes, and to do this you would use molar ratios to find how much reactant is used up based on the limiting reactant, then subtracting that number from the given amount of that reactant.

Maybe, but if that's the case then it shouldn't be much harder than finding how much product we can make. We would simply find it by using the remaining moles or even by subtracting what we have from the total
