<u>Answer:</u> The energy of a mole of photons is 
<u>Explanation:</u>
The relation between energy and wavelength of light is given by Planck's equation, which is:

where,
E = energy
h = Planck's constant = 
c = speed of light = 3.0\times 10^8m/s
= Avogadro's number = 
= wavelength of photon = 486 nm =
(Conversion factor:
)
Putting values in above equation, we get:

Hence, the energy of a mole of photons is 
Answer:
True
Step-by-step explanation:
An ionic bond is the attraction between a cation and an anion.
If there is no cation or anion, there is no ionic bond.
The majority of their bonds are nonpolar covalent carbon-to-hydrogen linkages.
The number of moles present in the FeSO4 are 0.055 mol.
<u>Explanation:</u>
- The mass of a substance containing the same number atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to 6.023 x 10^23. The moles of a substance can be determined by using the formula,
Number of moles = mass in grams / molecular mass
Given,
mass = 8.36 g,
molecular mass of FeSO4 = 151.908 g / mol
number of moles = 8.36 / 151.908
= 0.055 mol.
