Hey!!
here is your answer >>>
let us multiply the two numbers above!. we get,
(7.51)(6.50) ( 10) / 1.62 (10 )^-6
(7.51)(6.5)(10)^7/1.62
(751)(650)(10^3) / 1.62
301327.160 (10^3)
301327160 is the number.
Hope my answer helps!
Answer:
it looks good to me just pay attention to the subscriped, i always have trouble with that.
Explanation:
Static electricity. they have the same charge and same charges repel each other.
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
