Answer:
Solid particles are close together not gas particles
B I think is right. Hope this helps!
Answer:
It is a covalent bond because both carbon and oxygen are nonmetals. The formula will be CO² because the electrons between the atoms are being shared equally.
Broo whenever it sounds cool
Answer:
Perfectly Specified
Explanation:
Given,
Pressure = P = 0.9 atm
and the Boiling point = T
Number of phases P = 1
Number of components C = 1
According to Gibb's phase rule ,
F = C - P + 2
If
- F = 0, the system is perfectly specified
- F > 0, the system is under specified
- F < 0 the system is over specified
At P = 0.9 atm, boiling point is T i.e. Fixed equal to 96.7 °C (from steam table)
P is independent variable and T is dependent variable (depends on the value of P ).
In this case only two variables are required to fix the system pressure and temperature.
In the given problem, pressure is fixed so the temperature is also fixed. There is no requirement of any other variable.
Therefore degree of freedom,
F = 0
The system is perfectly specified.
