1
New cards

empirical formula

simplest whole n.o ratio of atom of each element in a compound

2
New cards

molecular formula

actual n.o of atoms of each element in a compound.

3
New cards

benefits of high atom economy

  • produces less waste, better for environment

  • more efficient use of raw materials, more sustainable

  • less expensive, separating desired product from waste products.

4
New cards

uncertainty calculation

range of values/2

5
New cards

percentage yield calculation

mass of actual yield/ mass of theoretical yield x100

6
New cards

atom economy equation

mr of desired product/ mr of reactants x100

7
New cards

atom economy

measure of efficiency of reaction

8
New cards

percentage uncertainty equation

uncertainty/value x100

9
