Answer:

See Explanation and Attachments => New concentration A = 0.10 mol/L

Explanation:

Explanation:

              A         +        B         ⇄        C       +        D

C(i):   0.20 mol      0.20 mol         0.4 mol       0.4 mol

ΔC:   -0.10 mol      -0.1 mol          +0.1 mol       +0.1 mol    

C(eq):  0.10 mol      0.10 mol          0.5 mol       0.5 mol

__________________

=> A & B react to form more C & D as reaction shifts right to establish new equilibrium with new concentration values. See attached diagram. => I call this the 'chemical see-saw analysis'.  

=> Also attached is a summary of stress factor effects of temperature and pressure-volume changes.

A balloon filled with helium gas has a volume of 500 mL at a pressure of 1 atm. The balloon is released and reaches an altitude
Rasek [7]
We are using the General gas equation P x V/K = P x V/K
1. P = 1atm V=500ml so PxV= 500 at 6.5km P = 0.5atm V = ? so P xV = 0.5 x V
(We don't have to worry about temperature!) 500 = 0.5 x V so V = 1000ml

2. NO CHANGE in pressure here so we have V/K V=2.75 K = 20 + 273=293 so V/K= 2.75/293
Next set V = 2.46 K = ? so V/K = 2.46/K then 2.75/293= 2.46/K so K=(293/2.75)x2.46
=262 K
Convert back to Celsius 262 - 273 = -11 C
It's raining so I have to rescue the laundry!
Laundry rescued!

3.Now we have to use all three variables. I am using 273K and 100kPa for STP.
P = 100 V = 700 K = 273 These are altered P - unknown, V = 200 K = 273+30=303
!00 x 700/273 = 256.4 this is equal to P x 200/303 = P x 0.66
so P = 256.4/0.66 = 388.48kPa

Lithium seems to have dramatic effects on the nervous system, yet our bodies seemingly never evolved to use lithium endogenously
Flauer [41]

Given its small size and high polarizing power, lithium is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.

<h3>What is lithium?</h3>

Lithium is a metal and a member of group 1 in the periodic table. It is a very small ion hence it has a different chemistry from the rest of the members of the group.

Lithium is not part of any of the biomolecules because given its small size and high polarizing power, it is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.
