Question 1

things to consider when sketching graphs

Answer 1

• points of axis intersection
• gradient where appropriate
• if it’s a function which is the sum of two functions, you can sketch the graphs separately and multiply the points to get the resultant points

Question 2

what do if given a complex kinematics question

Answer 2

• equate some property of the question
  e. g. if two objects travel at different speeds over different distances but in the same time then equate the equations for time.

Question 3

which acids are strong, which acids are weak

Answer 3

Strong = HCl, HNO3, H2SO4
Weak = CH3COOH, H3PO4

Question 4

what are some issues with the periodic table

Answer 4

• there are lots of exceptions with the periodicity rules
• Hydrogen and Helium don’t fit nicely
• It’s difficult to work out the properties of the super-heavy elements and therefore there is debate as to whether they should be included
