Q
What are the equations for kinetic energy and velocity 🟡
(And units)
A
t= a
d= m
v= ms-1
m=kg
KE= J
KE = 0.5mv^2
2KE = mv^2
V=d/t

Q
Use booklet 3.1.2.1 and Joe to make essential equations etc into fcs
A
YASA DO IT
3
Q
Percentage composition??
A
100% = mass / total rel atomic mass x 100
4
Q
Percentage yield
A
(Product mass obtained / max theoretical product mass) x 100
5
Q
Why aren’t products ever 100% percentage yield
A
- may be reversible
- some product lost (when separated from mixture/on isolation)
- side reaction (eg, a reactant and O2)
6
Q
Atom economy
A
(Mr of desired product / total product Mr ) x 100 —> INCLUDES MOLES IN EQUATION!
(Byproducts are the unwanted products)
