Answer:

The concentration of cyclopropane after 22.0 hour is 0.0457 M.

Explanation:

Conversion of cyclopropane into propene follows first order kinetics.

The integrated rate of first order kinetic is given by :

[A]=[A_o]\times e^{-kt}

[A_o] = Initial concentration of reactant

[A] = final concentration of reactant after time t

k = rate constant of the reaction

We have :

Rate constant of the reaction = k = 5.4\times 10^{-2} hour^{-1}

[A_o]=0.150 M

t = 22.0 hour

[A] =?

[A]=0.150 M\times e^{-5.4\times 10^{-2} hour^{-1}\times 22.hour}

[A]=0.0457 M

The concentration of cyclopropane after 22.0 hour is 0.0457 M.

How is the periodic table arranged
Mashcka [7]
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

The carbon-carbon double bond in ethene is ________ and ________ than the carbon-carbon triple bond in ethyne.
lbvjy [14]

Answer:

weaker and longer

Explanation:

Since there are 3 bonds in ethyne in comparision with the 2 bonds of ethyne between carbon atoms, they are attracted more to each other → the bond gets shorter . And since there are one more bond that supports the union → the bond gets stronger

thus the carbon-carbon double bond in ethene is weaker and longer than the carbon-carbon triple bond in ethyne
