It takes 495.0 kj of energy to remove 1 mole of electron from an atom on the surface of sodium metal. how much energy does it take to remove a single electron from an atom on the surface of solid sodium? energy = j. what is the maximum wavelength of light capable of doing this?

Explanation:

The work function of the sodium= 495.0 kJ/mol

It means that  

1 mole of electrons can be removed by applying of 495.0 kJ of energy.

Also,  

1 mole =

So,  

electrons can be removed by applying of 495.0 kJ of energy.

1 electron can be removed by applying of of energy.

Energy required =

Also,  

1 kJ = 1000 J

So,  

Energy required =

Also,

Where,  

h is Plank's constant having value

c is the speed of light having value

So,  

Also,  

1 m = 10⁻⁹ nm

So,  

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
