The binding energy of the electrons (also known as the work function of the surface) is determined as 2.43 x 10⁻¹⁹ J.
<h3>Binding energy of the electrons</h3>
The binding energy of the electrons is also known as work function of the metal and it is calculated as follows;
Ф = E - K.E
where;
Ф = hf - 86.2 kJ/mol
Ф = hc/λ - 86.2 kJ/mol
Ф = (6.63 x 10⁻³⁴ x 3 x 10⁸ )/515 x 10⁻⁹ - 86.2 kJ/mol
Ф = 3.86 x 10⁻¹⁹ J - (86200 J/mol)/(6.02 x 10²³)
Ф = 3.86 x 10⁻¹⁹ J - 1.43 x 10⁻¹⁹ J
Ф = 2.43 x 10⁻¹⁹ J

Answer:
Producers, consumers and decomposers
Explanation:
Producers can make their own food by capturing the sun's energy, but consumers and decomposers can't. Consumers need to eat other organisms to obtain energy. Decomposers are like the recyclers of nature. They obtain energy for their own needs while returning simple molecules to the environment.
I would say the first three. But I'm not 100% sure. I'm truly sorry if it's wrong

Answer:
The new pH of the solution 
Explanation:
Given
pH of bottle of Soda is 
As we know that
pH 
log [H+]
We will derive the hydrogen ion concentration when pH is
log [H+]
Taking anti-log on both the sides, we get -
H+ ion is equal to 
When the hydronuim ion concentration reduces by 
of the original concentration, the new hydrogen ion concentration becomes
The new pH is
![= - log [ 10^{-6}]\\= 6](https://tex.z-dn.net/?f=%3D%20-%20log%20%5B%2010%5E%7B-6%7D%5D%5C%5C%3D%206)
