  • Question 1

What is the method of chemical analysis that measures the amount of each substance present?

CORRECT ANSWER
quantitative analysis
EDDIE SAYS
The method of chemical analysis that measures the amount of each substance present is quantitative analysis.
  • Question 2

What element is F2 the formula for?

CORRECT ANSWER
fluorine
EDDIE SAYS
Fluorine: number 2 (2) at the bottom shows that this element is stable when two atoms join.
  • Question 3

What is the first step in any crime investigation?

CORRECT ANSWER
identify the substances collected from the crime scene
EDDIE SAYS
The first step in any crime investigation is to identify the substances collected from the crime scene.
  • Question 4

What type of chemists check the purity of water against government standards?

CORRECT ANSWER
analytical
EDDIE SAYS
Analytical chemists check the purity of water against government standards.
  • Question 5

What minerals does hard water contain? Tick two options below.

CORRECT ANSWER
calcium
magnesium
EDDIE SAYS
Hard water contains calcium and magnesium minerals.
  • Question 6

Name a method used for ‘softening’ hard water.

CORRECT ANSWER
ion exchange column
EDDIE SAYS
The method using an ion exchange column is one way of treating hard water.
  • Question 7

What are the two parts of a solution?

CORRECT ANSWER
solute
solvent
EDDIE SAYS
A solution is made up of a solute and a solvent.
  • Question 8

What does a mole of a substance equal to?

CORRECT ANSWER
the amount that contains an Avogadro's number of a specific particle
EDDIE SAYS
One mole of a substance equals to the amount that contains an Avogadro's number of a specific particle.
  • Question 9

All bases are water soluble.

  • Question 12

What is the name for the mathematical comparison of one quantity to another quantity?

CORRECT ANSWER
ratio
EDDIE SAYS
Ratio is the mathematical comparison of one quantity to another quantity, for example the 'mole ratio'.
  • Question 13

What are cations?

CORRECT ANSWER
They are positive ions attracted to the negative cathode.
EDDIE SAYS
