Answer:
46.9 atm
Explanation:
Applying Van der waals equation
P = [nRT/(V-nb)]- (an²/V²)............... Equation 1
Where P = pressure, T = temperature, n = number of moles, V = volume, R = Universal constant, a and b = gas constant
Given: n = 20 moles, R = 0.08205 L.atm/mol.K, T = 273 K, V = 10.0 L, a = 0.0341 atm.L²/mol², b = 0.0237L/mol
Substitute these values into equation 1
P = [(20×0.08205×273)/(10-20×0.0237)]-(0.0341×20²/10²)
P = (447.993/9.526)-0.1364
P = 47.028-0.1364
P = 46.9 atm
In drawing the Lewis structure for C2H2 (also called ethyne) you'll find that you don't have enough valence electrons available to satisfy the octet for each element (if you use only single bonds). The solution is to share three pairs of valence electrons and form a triple bond between the Carbon atoms in C2H2
Answer:
Explanation:
This indicate that there is a type of pressure or anticyclone that is affecting the area. This means Air would sink down slowly, instead of it rising and cooling.
It happen that Sometimes the clouds heat up and the liquid water will change into vapor. The water droplets present in the clouds will not be as heavy as the surrounding air
