<h2>Answer</h2>
1 meter = 1000 km
2500 meter = 2500/1000 km
= 2.5 km
That would be 0.5 g/ml because Density is equal to mass divided by volume and 8.5 is half of 17.
Answer:
The maximum wavelength of light for which a carbon-carbon triple bond could be broken by absorbing a single photon is 143 nm.
Explanation:
It takes 839 kJ/mol to break a carbon-carbon triple bond.
Energy required to break 1 mole of carbon-carbon triple bond = E = 839 kJ
E = 839 kJ/mol = 839,000 J/mol
Energy required to break 1 carbon-carbon triple bond = E'

The energy require to single carbon-carbon triple bond will corresponds to wavelength which is required to break the bond.
(Using planks equation)


The maximum wavelength of light for which a carbon-carbon triple bond could be broken by absorbing a single photon is 143 nm.
165 Pounds (lbs) = 74.84 Kilograms (kg)
1 lbs = 0.453592 kg 1 kg = 2.204623 lbs
KBr + Fs won't make a reaction because KBr is stable with an octet.
Bi+O2 probably won't occur because the O2 has a stable octet as well/
