I believe the answer is A) Metals. This is because metal is naturally extremely conductive. So if the researcher wanted to find a super conductive wire, then you would most certainly look in metal.
8:24 = 0.333(3) pints is one percent 0.333(3)* 100=33.333(3) pints will be 24% mixture with the water 33.3333-8=25.333 pints of water is required for producing 24% mixture
This means for every number of Carbon (C) atoms, there are twice as many Hydrogen (H) atoms with an additional two added onto that.
Therefore, if there is one Carbon Atom, and we multiply that by two, and then add an additional two, we get 4 Hydrogen atoms, so CH4, which is our first Formulae
Secondly, if we have eight Carbon Atoms, and we multiple that by two (16), and then add an additional two, we get 18 Hydrogen atoms, so C8H18, which is our second Formulae
The other Formulas do not follow this 'General Formula'
