Question

(Beg. Chem.) For the reaction below, you start wtih 10 moles of C and 16 moles of D. How many moles of F do you make and what is leftover? 2C + 4D --》 3F

Answer 1

The answer should be make 12 moles of F and have 2 moles of C leftover. Not sure how to get the leftover part.

Answer 2

identify the limiting reactant, then subtract those moles that reacted from the reactant with more moles (not the limiting reactant).

Answer 3

i know that sounds kind of confusing.

the limiting reactant is D, (i divided 16/4 =4, and 10/2=5 for C)

\(\dfrac{x}{2}=\dfrac{16}{4}\)

x=2*4=8

so you have 10-8=2 moles left
