Answer:
a. True
Explanation:
Theoretical yield is the amount of product that could be obtained if a chemical reaction has 100% efficiency.
Hope it helps...
We know that when calculating percent yield, we use the equation:

Since the quantities that we are given in the question are equal, we can just directly divide them to find percent yield:

So now we know that the percent yield of the synthesis is 87.27%.
What are some of the body's internal defenses. The skin helps protect stuff to!
So,
With addition, we the last digit we keep will be the one which is known for both individual values.
We know 2.13 to the hundredths, but we only know 1 to the ones. Therefore, we will round off in the ones place.
2.13 + 1 = 3.13 (unrounded)
= 3 (rounded)
Hope this helps!
