Regulations are put in place for the storing and transporting of chemicals. Hazard symbols and sealed containers prevent harm from coming to people + environment.
Green chemistry benefits:
- Increases efficiency 2) Reduces cost 3) Avoid risks
In I/GCSE Chemistry, Reducing use of petrochemicals, e.g. crude oil, will be more sustainable.
Rather, you should ferment renewable plant material using bacteria --> produces MALANIC ACID --> produces sorona --> used for clothes
Takes up land meant for food
Less energy used
Energy needed to produce more fertilisers + for harvesting
Saves crude oil
Working out percentage yield
E.g. 10g of CaCO3 is heated for 20mins. The product is 4.8g of CaO. What is the percentage yield?
= the efficiency --> how much product ends up as reactant
Formula: RAM of product / RAM of reactant x 100
Atom economy: 56 / 100 x 100 = 5.6%
You got it now!
