Answer:
If 0.20 mole of Cl 2 is added to the equilibrium mixture, will the concentration of PCl 5 increase or decrease? If the equilibrium constant for this reaction is expressed in terms of concentrations, written as follows: Here, , and represent the molar concentrations of, , and respectively. Chapter 10, Problem 60CQ is solved.
Step-by-step explanation:
The y-intercept of the first inequality is -1.
The y-intercept of the second inequality is +1.
The fourth graph has these correct.

C. f(x)=3(2)^x
Step-by-step explanation:
Answer:
W=2001.24 newton meters
Caution: check units and arithmetic - I often make errors.
Step-by-step explanation:
Work is force times distance.
Denote height by h where h=0 is at ground level.
Denote the mass of the bucket and rope at height h by m(h).
The rate at which the bucket loses mass with height is (20-16)/10=0.4 kg/m
The rate at which the rope between the bucket and the top of the building loses mass is 0.4 kg/m
The initial mass of the bucket and rope is
The mass at height h is
The force required at height h is
m(h)g
where g is the gravitational acceleration.
g=9.81 meters/sec/sec
The work required is
Where a=0 and b=10
g(244-40)=204g
W=2001.24 newton meters
