The answer is d electrons orbit the nucleus of an atom in fixed electron shells
Let's find the number of moles first.
Number of moles = mass/molar mass
Molar mass = 51.9961
Number of moles = 13/ 51.9961 = 0.2500.
1 mole of any particle contains 6.02 * 10^(23) atoms.
Hence 0.2500 moles contains X
Hence X = 0.25 * 6.022 * 10^(23) = 1.5055 * 10^(23)
Answer:
45200J
Explanation:
Given parameters:
Heat of vaporization of water = 2260J/g
Mass of steam = 20g
Temperature = 100°C
Unknown:
Energy released during the condensation = ?
Solution:
This change is a phase change and there is no change in temperature
To find the amount of heat released;
H = mL
m is the mass
L is the latent heat of vaporization
Insert the parameters and solve;
H = 20g x 2260J/g
H = 45200J
