Resource summary

Question 1

Question
Until recently, the elements were arranged in order of their [blank_start]atomic mass[blank_end].
Answer
  • atomic mass
  • atomic number
  • names (alphabetically)

Question 2

Question
What were the problems with Newlands' Law of Octaves?
Answer
  • The groups contains elements that didn't have similar properties e.g. C and Ti
  • He mixed up metals and non-metals e.g. O and Fe
  • He didn't leave any gaps for undiscovered elements
  • They weren't arranged in order of atomic mass
  • They went against the Church

Question 3

Question
Group 1 metals become [blank_start]more[blank_end] reactive as you go down the group because the outer electron is more easily lost as it's further from the nucleus.
Answer
  • more
  • less

Question 4

Question
Label the halogen with the dot.
Answer
  • Fluorine
  • Chlorine
  • Bromine
  • Iodine

Question 5

Question
Transition metals are less reactive, denser, stronger and harder than Group 1 metals
Answer
  • True
  • False

Question 6

Question
Permanent hardness is caused by [blank_start]calcium sulphate[blank_end].
Answer
  • calcium sulphate
  • hydrogencarbonate ions
  • sodium hydroxide

Question 7

Question
Which of these is the order water is treated in?
Answer
  • Screening, removal of solids and microbes, filtration and chlorination
  • Filtration, screening, chlorination, removal of solids and microbes
  • Removal of solids and microbes, filtration, chlorination and screening

Question 8

Question
Equilibrium means the amounts of reactants and products reach a certain balance and stay there.
Answer
  • True
  • False

Question 9

Question
If you raise the pressure, it will encourage the reaction which produces [blank_start]less[blank_end] volume.
Answer
  • less
  • more

Question 10

Question
What conditions are needed for the Haber Process?
Answer
  • Pressure: 200 atm
  • Temperature: 450 degrees C
  • Catalyst : Iron
  • Pressure: 900 atm
  • Temperature: 20 degrees C
  • Catalyst: Magnesium

Question 11

Question
Alcohols have the functional [blank_start]-OH[blank_end] group.
Answer
  • -OH
  • -COOH
  • -COO-

Question 12

Question
The first 3 alcohols...
Answer
  • Dissolve completely in water to form neutral solutions
  • React with sodium to give hydrogen & alkoxides
  • React with carboxylic acids to form an ester + water
  • Don't react with anything
  • Are used as fuels and solvents
  • Are poisonous

Question 13

Question
Carboxylic acids don't ionise completely (release H+ ions) and so form [blank_start]weak acidic[blank_end] solutions.
Answer
  • weak acidic
  • strong acidic
  • weak alkaline
  • strong alkaline

Question 14

Question
How do you work out concentration?
Answer
  • Moles / Volume
  • Moles * Volume
  • Mass / Relative Formula Mass

Question 15

Question
In an exothermic reaction, the energy released in bond formation is [blank_start]greater[blank_end] than the energy used in breaking old bonds.
Answer
  • greater

Question 16

Question
What are the problems with using hydrogen fuel cells?
Answer
  • Hydrogen is gas - takes up more space to store
  • It's very explosive - difficult to store safely
  • Hydrogen fuel is usually made from hydrocarbons or electrolysis of water - fossil fuels & electricity
  • They produce pollutants
  • They don't produce much power

Question 17

Question

Answer
  • colourless
  • pink
  • blue

Question 18

Question

Answer
  • silver nitrate solution
  • dilute hydrochloric acid
  • barium chloride solution

Question 19

Question

Answer
  • barium chloride solution
  • silver nitrate solution
  • nitric acid

Answer
  • True
  • False
