^ limiting reagent questions are quite simple.
1. Find the balanced chemical equation.
2. Assume one of the reagents have UNLIMITED supply and calculate the amount of products it will yield.
3. Assume the other reagents have UNLIMITED supply and calculate the amount of products (same product as above) it will yield.
4. Repeat step 3 if the equation contains more than 2.
5. Compare the amount of products, the one with the least amount of yield is the limiting reagent. <- meaning you will have excess of the other ones.
