Answer:

Buffer.

Explanation:

A buffer solution is a solution made out of a weak acid/base and its conjulgated base/acid. This kind of solution is special because it is resistent so pH change because it can react with acids and with bases, thus it keep pH withing a determined range as long as it is not fully consumed by excess adition of acid/base.

Tom [10]

Molar mass of vitamin B1, C12H17N4OS = 265.34 g/ mol

Molar mass of vitamin B2, C17H20N4O6 = 376.37 g/ mol

Molar mass of vitamin B5, C9H17NO5 = 219.24 g/ mol

Molar mass of vitamin B6, C8H11NO3 = 169.18 g/ mol

Molar mass of vitamin B7, C10H16N2O3S = 244.31 g/ mol

Now,

Order of increasing molar mass = B6 < B5 < B7 < B1 < B2

Phosgene (COCl2) is a toxic substance that forms readily from carbon monoxide and chlorine at elevated temperatures: CO(g) + Cl2
lapo4ka [179]

Answer: Concentration of CO = 0.328 M

Concentration of Cl_2 = 0.328 M

Concentration of COCl_2 = 0.532 M

Explanation:

Moles of  CO and Cl_2 = 0.430 mole

Volume of solution = 0.500 L

Initial concentration of CO and Cl_2  =\frac{moles}{volume}=\frac{0.430}{0.500}=0.860M

The given balanced equilibrium reaction is,

                            CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)

Initial conc.          0.860M     0.860M           0

At eqm. conc.    (0.860-x) M  (0.860-x) M     (x) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[COCl_2]}{[CO][Cl_2]}

Now put all the given values in this expression, we get :

4.95=\frac{x}{(0.860-x)^2}

By solving the term 'x', we get :

x =  0.532 M

Thus, the concentrations of CO,Cl_2\text{ and }COCl_2 at equilibrium are :

Concentration of CO = (0.860-x) M =(0.860-0.532) M = 0.328 M

Concentration of Cl_2 =  (0.860-x) M  =  (0.860-0.532) M = 0.328 M

Concentration of COCl_2 = x M = 0.532 M
