1Until recently, the elements were arranged in order of their [blank_start]atomic mass[blank_end].
- Aatomic mass
- Batomic number
- Cnames (alphabetically)
2What were the problems with Newlands' Law of Octaves?
- AThe groups contains elements that didn't have similar properties e.g. C and Ti
- BHe mixed up metals and non-metals e.g. O and Fe
- CHe didn't leave any gaps for undiscovered elements
- DThey weren't arranged in order of atomic mass
- EThey went against the Church
3Group 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.
- Amore
- Bless
4Label the halogen with the dot.
- AFluorine
- BChlorine
- CBromine
- DIodine
5Transition metals are less reactive, denser, stronger and harder than Group 1 metals
- ATrue
- BFalse
6Permanent hardness is caused by [blank_start]calcium sulphate[blank_end].
- Acalcium sulphate
- Bhydrogencarbonate ions
- Csodium hydroxide
7Which of these is the order water is treated in?
- AScreening, removal of solids and microbes, filtration and chlorination
- BFiltration, screening, chlorination, removal of solids and microbes
- CRemoval of solids and microbes, filtration, chlorination and screening
8Equilibrium means the amounts of reactants and products reach a certain balance and stay there.
- ATrue
- BFalse
9If you raise the pressure, it will encourage the reaction which produces [blank_start]less[blank_end] volume.
- Aless
- Bmore
10What conditions are needed for the Haber Process?
- APressure: 200 atm
- BTemperature: 450 degrees C
- CCatalyst : Iron
- DPressure: 900 atm
- ETemperature: 20 degrees C
- FCatalyst: Magnesium
11Alcohols have the functional [blank_start]-OH[blank_end] group.
- A-OH
- B-COOH
- C-COO-
12The first 3 alcohols...
- ADissolve completely in water to form neutral solutions
- BReact with sodium to give hydrogen & alkoxides
- CReact with carboxylic acids to form an ester + water
- DDon't react with anything
- EAre used as fuels and solvents
- FAre poisonous
13Carboxylic acids don't ionise completely (release H+ ions) and so form [blank_start]weak acidic[blank_end] solutions.
- Aweak acidic
- Bstrong acidic
- Cweak alkaline
- Dstrong alkaline
14How do you work out concentration?
- AMoles / Volume
- BMoles * Volume
- CMass / Relative Formula Mass
15In an exothermic reaction, the energy released in bond formation is [blank_start]greater[blank_end] than the energy used in breaking old bonds.
- Agreater
16What are the problems with using hydrogen fuel cells?
- AHydrogen is gas - takes up more space to store
- BIt's very explosive - difficult to store safely
- CHydrogen fuel is usually made from hydrocarbons or electrolysis of water - fossil fuels & electricity
- DThey produce pollutants
- EThey don't produce much power
17Aluminium hydroxide is a white precipitate at first but redissolves in excess NaOH to form a [blank_start]colourless[blank_end] solution.
- Acolourless
- Bpink
- Cblue

- Abarium chloride solution
- Bsilver nitrate solution
- Cnitric acid
20A more reactive halogen can displace a less reactive halogen from an aqueous solution of its salt.
- ATrue
- BFalse
