Answer: LOL. I think thats how-
Answer:
It is because water molecules in the air condensed on to the container of the drink.
Explanation:
The way this works is the water molecules outside are hot and in the gas state, so when they come into contact with the cold side of the container they lose energy due to heat transfer between the molecules and the container, becoming a liquid on the side of the drink.
Answer:
B
Explanation:
The particles move freely
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
