`let's just consider the concept of stoichiometry without any confusing chemicals. here is a generic equation: 2a + 6b ? 3c. if you mix 4 units of a and 11 units of b, what would be the theoretical yield of c?

a. 8

b. 3

c. 6

d. 5.5

e. none of the above

Option D. 5.5

Explanation:

The equation is this:

2A + 6B  ⇒  3C

With the amounts that we were given, let's determine which is the limting reactant

2 A reacts with 6 B

4 A will react with ( 4 .6)/2 = 12B

I have 11 B, so the limiting is B

6 B react with 2 A

11 B will react with (11 .2 )/6 =3.66 A

I have 4 A, so A is the excess.

6 B produce 3 C

11 B will produce ( 11 .3)/6 = 5.5C

sure what is it? ^w^
