Answer:
344 nm is the longest wavelength of radiation with enough energy to break carbon-carbon bonds.
Explanation:
,ΔH = 348 kJ/mol
Energy required to break 1 mole of C-C bond = 348 kJ
Energy required to break 1 C-C bond = E

Energy related with the wavelength of light is given by Planck's equation:





344 nm is the longest wavelength of radiation with enough energy to break carbon-carbon bonds.
C=2.41 g/L
m(NaCl)=0.291 g
c=m(NaCl)/v
v=m(NaCl)/c
v=0.291/2.41= 0.1207 L = 120.7 mL
<u>Answer:</u> The final volume of the reaction is 4.69 L
<u>Explanation:</u>
The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.
The equation used to calculate number of moles is given by:

where,
are the initial volume and number of moles
are the final volume and number of moles
We are given:

Putting values in above equation, we get:

Hence, the final volume of the reaction is 4.69 L
answer:
atomic number
the same chemical element is characterized by the number of protons in the nucleus that determines the total positive charge.
