Question 1

Question
What are isotopes?
Answer
  • Different forms of the same element which have the same number of protons and a different number of neutrons.
  • Different forms of the same element which have the same number of protons and a same number of neutrons.
  • Different forms of the same element which have the different number of protons and a same number of neutrons.

Question 2

Question
what is ionic bonding?
Answer

Question 3

Question
Ionic compounds have a regular lattice structure.
Answer
  • True
  • False

Question 4

Question
Silver Chloride is soluble.
Answer
  • True
  • False

Question 5

Question
Tick all correct flame tests.
Answer
  • Sodium ions give an orange/yellow flame
  • Sodium ions give an pink flame
  • potassium ions give a red flame
  • potassium give a lilac flame
  • calcium ions give a blue flame
  • Copper ions give a bluey-green flame

Question 6

Question
Barium sulfate, used in x-rays is swallowed by patients in barium meals. It is toxic.
Answer
  • True
  • False

Question 7

Question
How do you test for carbonates, for example Carbon dioxide?
Answer
  • Add dilute HCL and barium chloride solution. A white precipitate means Carbon dioxide is there.
  • Bubble it through limewater, if it's carbon dioxide it will go cloudy.
  • flame test it! If it turns white its Carbon dioxide

Question 8

Question
Simple molecular covalent substances have which of these characteristics?
Answer
  • Very strong covalent bonds form small molecules of two or more atoms.
  • Very weak inter-molecular forces.
  • High melting and boiling points.
  • Conducts electricity.

Question 9

Question
Giant Molecular Covalent Substances have which of these characteristics, tick all the correct answers.
Answer
  • They're similar to ionic lattices.
  • They're soluble in water.
  • (except for graphite). Don't conduct electricity.
  • Diamond and Graphite are main examples.

Question 10

Question
which process is better for separating miscible ( mixable) mixtures, separating funnels or fractional distillation?
Answer
  • Separating funnels.
  • Fractional distillation.

Question 11

Question
Alkali metals ( in group one of the periodic table) have which properties?
Answer
  • react vigorously with water.
  • The further you go down in the group, the more reactive they get.
  • Reaction with water produces carbon dioxide

Question 12

Question
When bonds break they form an endothermic reaction.
Answer
  • True
  • False

Question 13

Question
Which four things can increase the rate of reaction?
Answer
  • Surface area
  • concentration
  • how heavy the object is
  • a catalyst
  • temperature
  • covering it with a hat

Question 14

Question
select the correct answers.
Answer
  • The relative atomic mass is the same as the elements mass number.
  • The relative atomic mass is the same as the elements atomic number
  • Relative formula mass is all the relative atomic masses in that compound added together.
