The correct Anwser is enzymes
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.
Hey there!
Ba(NO₃)₂
Ba: 1 x 137.327 = 137.327
N: 2 x 14.007 = 28.014
O: 6 x 16 = 96
-----------------------------------
261.341 g/mol
The molar mass of Ba(NO₃)₂ is 261.341 g/mol.
Hope this helps!
