I totally need help on these problems about limited reactants. My teacher gave me an example: You intend to use the following recipe (Caution: it will turn your mouth bright red—be careful):
1 can frozen white grape juice concentrate
2 Tbs. red food color
1 tsp. yellow food color
Suppose for your movie you need to make 10 batches of this fake blood. In your freezer you have 9 cans of white grape juice, you have 15 tablespoons of red food color and you have 8 teaspoons of yellow food color. Obviously, you need to go to the store, but how many batches can you make?
9 cans of white grape juice will make 9 batches.
15 tbs. of red food color can make 7.5 batches (2 tbs. each)
8 tsp. of yellow food color can make 8 batches.
So...The answer must be 7.5 batches if you want to make half a batch.
Then she gave me these equations to solve:
1. How many grams SO2 can be formed from 20.0 g of S and 160g O2?
2. How many gramsSO2 can be formed from 20 g S and 15.0 g of O2?
(Plese show the balanced equation and your work.)
The balanced equation is S + O2 ---> SO2. What I don't know how to do is the work to figure out the equations above.
