Explain why an equilibrium between Br
2 (
l ) and Br
2 (
g ) would not be established if the container were not a closed vessel shown in
[link] .
Equilibrium cannot be established between the liquid and the gas phase if the top is removed from the bottle because the system is not closed; one of the components of the equilibrium, the Br
2 vapor, would escape from the bottle until all liquid disappeared. Thus, more liquid would evaporate than can condense back from the gas phase to the liquid phase.

Among the solubility rules previously discussed is the statement: All chlorides are soluble except Hg
2 Cl
2 , AgCl, PbCl
2 , and CuCl.
(a) Write the expression for the equilibrium constant for the reaction represented by the equation
Is
K
c >1,<1, or ≈ 1? Explain your answer.
(b) Write the expression for the equilibrium constant for the reaction represented by the equation
Is
K
c >1,<1, or ≈ 1? Explain your answer.
(a)
K
c = [Ag
+ ][Cl
− ]<1. AgCl is insoluble; thus, the concentrations of ions are much less than 1
M ; (b)
>1 because PbCl
2 is insoluble and formation of the solid will reduce the concentration of ions to a low level (<1
M ).

Among the solubility rules previously discussed is the statement: Carbonates, phosphates, borates, and arsenates—except those of the ammonium ion and the alkali metals—are insoluble.
(a) Write the expression for the equilibrium constant for the reaction represented by the equation

Benzene is one of the compounds used as octane enhancers in unleaded gasoline. It is manufactured by the catalytic conversion of acetylene to benzene:
Which value of
K
c would make this reaction most useful commercially?
K
c ≈ 0.01,
K
c ≈ 1, or
K
c ≈ 10. Explain your answer.
Since
a value of
K
c ≈ 10 means that C
6 H
6 predominates over C
2 H
2 . In such a case, the reaction would be commercially feasible if the rate to equilibrium is suitable.

the demand of a good rises, causing the demand for another good to fall
is it possible to leave every good at the same level
Joseph
I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost
6% more than previous year? Provide with reasoning.
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.

I want to know how can we define macroeconomics in one line
Muhammad
it must be .9 or 0.9
no Mpc is greater than 1
Y=100+.9Y+50
Y-.9Y=150
0.1Y/0.1=150/0.1
Y=1500

hi can someone help me on this question
If a negative shocks shifts the IS curve to the left, what type of policy do you suggest so as to stabilize the level of output?
discuss your answer using appropriate graph.
if interest rate is increased this will will reduce the level of income shifting the curve to the left ◀️
