Answer:
37.5 moles of O2 needed
Explanation:
2 moles of C6H6 need 15 moles of O2
5/2 * 15 = 37.5 of O2 needed
Answer:
You could have a scratch test, fog test, break test, theres many tests you could perform to see if it is a diamond.
Explanation:
yes because they are inert or inactive at normal temperature, they are inactive because their outer most orbit contain either 2 or 8 electrons.that make them stable
Answer:
a) Absorbance
b) The absorb light most strongly in 580nm
Explanation:
Beer-Lambert law relates concentration with light absorbance. The more concentrated solution are the more molecules and the most absorbance.
Wavelenght depends of composition of solution and doesn't change with different concentrations of the same solution.
Transmittance is inversely proportional to absorbance. Thus, the more concentrated solution the less transmittance.
Colored compounds are absorb energy of visible radiation. The colour that we see is a result of the absortion of complimentary colour (Colour wheel). Thus, a blue-green solution absorb energy of ≈600 nm. Thus, the absorb light most strongly in 580nm.
