Answer:
0.0984mol of F2
Explanation:
The equation for the reaction is given below:
Kr + F2 → KrF2
Let us convert 12g of KrF2 to mole. This is illustrated below
Molar Mass of KrF2 = 84 + (2x19) = 84 + 38 = 122g/mol
Mass of KrF2 = 12g
Number of mole = Mass /Molar Mass
Number of mole of KrF2 = 12/122 = 0.0984mol
From the equation,
1mole of F2 produced 1mole of KrF2.
Therefore 0.0984mol of F2 will produce 0.0984mol of KrF2
Water: hydrogen bonding
carbon tetrafluoride: dispersion or Van del Waals
dichloromethane: dipole-dipole
Answer: true
Explanation: Electrons orbit the nucleus of an atom the way that planets revolve around the Sun. The electrons are like the planets in the solar system. The sun is like the nucleus in the solar system. The answer to the question is true.
