Percentage Yield And Reversible Reactions Flashcards
1
Q
How can the predicted yield be calculated?
A
From the balanced equation
2
Q
How is the percentage yield calculated?
A
Percentage yield = (actual yield/predicted yield)x100
3
Q
What does an 100% percentage yield mean?
A
You got all the product you were expecting
4
Q
What does a 0% percentage yield mean?
A
That no reactants were converted into product
5
Q
Is it possible to get an 100% percentage yield?
A
No
6
Q
What is a reversible reaction?
A
A reactions where the products of the reaction can themselves react to produce the original reactants
7
Q
What are the three reasons for the yield being less than 100%?
A
- the reaction is reversible
- product lost during filtering
- unexpected reactants happening which use up reactants
8
Q
What does the percentage yield teach you about an experiment?
A
How successful the experiment was
