⩥ thing included in each stage of an LCA.
Answer: transport and distribution
⩥ how an LCA can be used.
Answer: to compare and evaluate the impact of the use of different
materials for the same purpose, and the use of the same material for
different jobs
⩥ flaw of LCAs.
Answer: they aren't purely objective, as some parts such as pollutant
effect can't easily be assigned a value, so someone needs to make a
judgement
⩥ importance of reducing the use of, recycling and reuse of, materials.
Answer: extracting and using them uses limited resources, is expensive
and has waste and environmental impacts
,⩥ problem with many things humans use in everyday life.
Answer: made from limited raw materials, and the energy used to
process these comes from limited resources
⩥ problem with accessing raw materials in the first place.
Answer: causes environmental issues from mining or quarrying
⩥ how a reaction stops.
Answer: when all the particles of one of the reactants are used
⩥ limiting reactant.
Answer: the first reactant to be used up
⩥ what the limiting reactant does.
Answer: limits the amount of product that can be formed
⩥ how to ensure all the limiting reactant has reacted.
Answer: use an excess of other reactants
