Answer :
The substance is in the gas phase only in region → 5
The substance is in both the liquid and the solid phase in region → 2
The substance is in only the liquid phase in region → 3
The melting point is the temperature at region → 2
The boiling point is the temperature at region → 4
Explanation :
Six phases of substance:
- Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.
- Freezing : In this process the phase changes from liquid state to solid state at constant temperature.
- Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.
- Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.
- Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.
- Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.
Missing in your question the K constant value =2.99X10^-7
The reaction equation:
SOCl2 ⇄ SO2 +Cl2
initial 0.195 0 0
-X +X +X
final (0.195-X) X X
K= [SO2][Cl2]/SOCl2
by substitution
2.99X10^-7 = (X)(X)/(0.195-X)
2.99X10^-7 = X^2 / (0.195-X) by solving this equation
∴X = 0.00024 = 2.4 X10^-4
∴[Cl2] = 2.4X10^-4 m
Answer:
increase
Explanation:
At the skate park when a skateboarder wants to skate down a ramp, the skate boarder wishes to move faster and with speed so that it help him to skate more time. This can only be achieved if the all the forces acting on him will increase as he skates down the ramp without much of the frictional force acting on the wheels of the skate board. The less friction force acts on the wheel, the more he can skate with more speed.
Thus, the skateboarder wants the force to be increase that is acting on him.
