The engineer would C. research new scientific findings about ocean cleanup.
A competent engineer would already know what has been done in the past to clean up oceanic oil residue.
Identifying needs and evaluating benefits and challenges are <em>value judgements</em> that are more appropriate for other decision-makers such as politicians.
the properties of liquids usally wet, wet shows expiation on heating and contracting on cooling
NaOH
Na=23
O=16
H=1
SO,NaOH=23+16+1
NaOH=40g/mol
42% of 40=42/100x40
oxygen is the compound
density=mass/volume
1.30=mass/6
mass=7.8g
Gas --> separated particles, usually a great amount away from each other
Liquids --> particles are closer together but not always touching
Solids --> particles are solidly packed together, not one is distant
hope this helped, have a fantastic night/day/morning :)
