reacting quantities Flashcards
1
Q
how do you calculate % atom economy?
A
(mass of desired products / total mass of all products) x100
2
Q
how do you calculate % yield?
A
(actual yield / theoretical yield) x100
3
Q
how do you work out the limiting reagent of a reaction?
A
divide the moles by the molar ratio. the smallest answer is the limiting reagent
4
Q
why is it beneficial that chemical processes have a high atom economy?
A
-they produce a large proportion of desired products and few waste products
-they make the best use of natural resources
