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
The answer for this question would be 6 L
They have strong intermolecular forces between their atoms, hence why more heat is necessary.
So there are 2 N, 9 H, 1 P and 4 O. so N:H:P:O is 2:9:1:4? i think
