Answer: Rf value =
◍ symbol for aqueous solution.
, Answer: aq
◍ What are the relative charges of the proton, neutron and electron?.
Answer: +1, 0, -1
◍ green.
Answer: NaOH precipitate test: Fe²⁺
◍ formula to find mean rate of reaction (using quantity of product formed).
Answer: RoRxn = quantity of product formed ÷ time
◍ What occurs in metallic bonding?.
Answer: A lattice of ions surrounded by delocalised ('free') electrons
◍ the process of oxidising either hydrocarbons or carbohydrates quickly.
Answer: combustion
◍ each fraction of crude oil contains.
Answer: similar alkanes
◍ Which electrode is positive and which is negative?.
Answer: Anode(+) and the Cathode (-)
◍ Energy Transfer practical (measuring).
Answer: 1) take temperature of the reactants, mix them in polystyrene cup
and measure temp. at the end of reaction2) issue is energy lost to
surroundings3) able to reduce it by putting cotton wool around the cup in
solution to insulate it (or add a lid).
◍ electrolysing a molten simple ionic compound using inert electrodes.
Answer: metal formed at cathode (metal cations are attracted), non-metal
formed at anode (non-metal anions are attracted)
◍ Properties of Graphite?.
Answer: Conductor of electricity, layers able to slide past each other
◍ What takes place in a Displacement reaction?.
Answer: When a more reactive metal displaces another less reactive metal
from a compound.
,◍ Give 2 examples of an Endothermic reaction..
Answer: Photosynthesis, Evaporating liquids and thermal decomposition
◍ What are the pH of alkalis?.
Answer: 8-14
◍ Evaporation.
Answer: 1) pour solution into evaporating dish2) slowly heat solution.
Solvent will evaporate, eventually crystals will form3) Keep heating until all
you have is crystals
◍ percentage of crude oil used as fuel for heating/transport.
Answer: > 85%
◍ What are Allotropes of Carbon?.
Answer: Structures made of same element but arranged differently.
◍ brown.
Answer: NaOH precipitate test: Fe³⁺
◍ What are some properties of metals?.
Answer: Good conductors of heat and electricity
◍ How are particles arranged in a Solid?.
Answer: Particles in a regular arrangement and vibrate in their fixed
positions. They cannot be compressed
◍ steeper tangent shows the RoRxn is.
Answer: faster
◍ What is the Acronym for Oxidation and Reduction?.
Answer: OIL RIG (Oxidation Is Gained / loss of electrons, Reduction Is
Loss / gain of electrons)
◍ What are some properties of Ionic substances?.
Answer: High melting points and boiling points
◍ cracking: formula.
Answer: long alkane + cracking short alkane + short alkene
, ◍ Name the 3 states of Matter.
Answer: Solid, Liquid and Gas
◍ minimum amount of energy required in a collision for a reaction to take
place.
Answer: activation energy
◍ What can electrolysis be used for?.
Answer: To obtain pure metals from an ore or compound
◍ What bonds in Ionic bonding?.
Answer: Metals bond to non-metals
◍ What are their relative masses?.
Answer: 1, 1, 0 (very small)
◍ What do Group 1 Ions look like?.
Answer: They are all (1)+
◍ greenhouse effect (2).
Answer: earth absorbs short λ EM radiation and warms up, but longer λ IR
radiation is radiated from the Earth as heat
◍ Simple Distillation.
Answer: 1) Solution heated (thing with lowest boiling point evaporates
first)2) vapour is then cooled, condensed and collected3) rest of solution left
behind
◍ warmth, shelter, food and transport.
Answer: the Earth provides humans with...
◍ there is only a certain amount of them.
Answer: finite means...
◍ Crystallisation.
Answer: 1) Pour solution into evaporating dish2) gently heat solution3)
some solvent will evaporate once that happens (or crystals begin to form)
remove from heat and let it cool4) salt should begin to form crystals as it
