Answer:

The answer to the question is;

The concentration of AB, which is written as [AB] after 11.9 s is 0.328 M.

Explanation:

The form of the equation for the second order integrated rate law is

y = mx +b

Where:

y = 1/A

m = k

x = t and

b = 1/A₀

Therefore for the reaction

AB(g) → A(g) + B(g)

rate = k[AB]² and k = 0.20 L/mol·s we have

\frac{1}{[AB]} = \frac{1}{[AB]_0} + kt

Since the initial concentration of AB is [AB]₀ = 1.50 M,

t = 11.9 s

k = 0.20 L/mol·s

we have

\frac{1}{[AB]} = \frac{1}{1.50 M/L} + 0.20 L/(mol)(s)*11.9 s

\frac{1}{[AB]} = 3.047 L/mol

[AB] = 0.328 M

The concentration of AB after 11.9 s is 0.328 M.

What is the molar mass of magnesium tartrate
Leya [2.2K]

Answer:

172.385 g/mol

Explanation:

Magnesium Tartrate is C4H4MgO6

C - 12.01 g/mol

H - 1.01 g/mol

Mg - 24.305 g/mol

O - 16.00 g/mol

12.01(4) + 1.01(4) + 24.305 + 16(6) = 172.385 g/mol

Draw the lewis structure of the hypochlorite ion clo- . include lone pairs
Dmitry_Shevchenko [17]

Solution:- Hypochlorite ion ClO^- has one Cl and one O atom. Cl has 7 valence electrons and O has 6 valence electrons. Since there is one negative charge on the ion,

total valence electrons = 7 + 6 +1 = 14

(note:- if there is negative charge then it is added  and if there is positive charge then it is subtracted while calculating the valence electrons)

Both Cl and O atoms wants to complete their octet and so for this we put a single bond between them. Single bond means two electrons, so the remaining electrons would be 14 - 2 = 12

It means 12 electrons will be placed as lone pair of electrons. To complete the octet, we put 6 dots around each of the atom. Oxygen is more electron negative than Cl, so we show the -1 charge for oxygen.
