What s the formula to calculate percentage yield
|
Actual Mass ÷ Predicted mass × 100
|
|
|
What is actual yield
|
Is how much product is made when the experiment is carried out in real life
|
|
|
What is the predicted yield
|
For a given mass of reactants, maximum possible mass of a certain product that could be made
|
|
|
What does 0% yield mean
|
no product is made
|
|
|
Why is it that reactions don't make 100% yield
|
Filtering
Evaporation Transferring liquids Not all reactants react to make a product |
|
|
Why do industrial processes need a high percentage yield as possible
|
Reduces the waste of product
Reduces the cost of process |
|
|
What is atom economy?
|
The measure of waste atoms when making a chemical
|
|
|
Is a process with a high atom economy "green" and why
|
Yes, because is is wasting very little
|
|
|
What does 100%atom economy mean
|
That all atoms in the reactants have been converted into the desired product
|
|
|
What's the formula for atom economy
|
Mr of desired products ÷ Sum of Mr of all products × 100
|
|
|
What is Mr
|
The reacting mass
|
|
|
Why do industrial processes need a high atom economy
|
Reduces the production of unwanted products
Makes the process more sustainable |
