so that the can fiuger out what it is for the answer
Explanation:
Answer:
Length = 393pm, Density = 21.3 g/cm^3.
Explanation:
From the question above, we have the following parameters or data which is going to aid in solving the above Question.
=> The radius of a platinum atom = 139 pm.
Therefore, the length can be calculated by making use of the formula given below:
Length = 2 √( 2r) = 2 × √ (2 × 139 × 10^-12m ) = 393 × 10^-10 m = 393pm.
The density can be calculated by making use of the chemical formula given below:
Density = mass ÷ volume = (195.064/ 6.02 × 10^23) ÷ (3.93 × 10^-10/ 10^-2) = 21.3 g/cm^3.
<u>Answer:</u> The value of 
for the final reaction is 
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u> 
<u>Equation 2:</u> 
The net equation follows:
As, the net reaction is the result of the addition of reverse of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of inverse of first equilibrium constant and the inverse of second equilibrium constant.
The value of equilibrium constant for net reaction is:
We are given:
Putting values in above equation, we get:
Hence, the value of for the final reaction is
Answer:
Part A. F + e⁻ → F⁻
Part B. -820 kJ
Part C. -5.45x10⁻²² kJ
Explanation:
Part A
The fluoride anion is formed when fluorine accepts an electron:
F + e⁻ → F⁻
Part B
The electron affinity is the energy necessary for the atom to accept 1 electron, which is exothermic, so it's negative. The total energy q is the electron affinity multiplied by the number of moles:
q = -328 kJ/mol * 2.5 mol
q = -820 kJ
Part C
By the Avogadros' number
1 mol --------- 6.02x10²³ atoms
x --------- 1 atom
By a simple direct three rule:
x = 1.66x10⁻²⁴ mol
So, the energy for 1 atom is:
q = -328 kJ/mol * 1.66x10⁻²⁴ mol
q = -5.45x10⁻²² kJ
