What is the wavelength, in nm, of radiation which has an energy if 3.371 x 10^-19 joules per photon?

a) 655.9nm
b)152.5nm
c)170.0nm
d) 589.3nm
e)745.1nm
explain

The correct option is:

D) 589.3 nm

Explanation:

Energy of one photon =

Hence, the wavelength (in nm) of radiation is 589.7nm (approximately equal to 589.3nm)

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
