Question 1

why might the mass of the product be lower than the maximum possible mass

Answer 1

reaction is reversible
reaction is not complete
unexpected side reaction
products may need purified

Question 2

how do you calculate percentage yield

Answer 2

(actual yield / theoretical yield) X100

Question 3

define theoretical yield

Answer 3

the maximum possible mass of a product assuming a complete reaction with no losses

Question 4

define actual yield

Answer 4

the actual mass obtained from a reaction

Question 5

what needs to be considered in industry when assessing a reactions feasibility

Answer 5

scarcity/abundance of raw materials & reactants
cost of raw materials & reactants
quantity of energy needed

Question 6

how do you calculate atom economy

Answer 6

`(molar mass of desired product/ sum of molar mass of all products) X100

Question 7

what atom economy do addition reactions generally have

Answer 7

100%

Question 8

what atom economy do elimination & substitution reacts generally have

Answer 8

lower atom economy
