Cyclopropane is converted to propene in a first–order process with a rate constant of 5.4 × 10–2 hour–1 . The initial concentrat
Hitman42 [59]

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.

While preforming an experiment involving colors and heat,Susan noticed that the black paper was warmer than the white piece of p
Firdavs [7]

Answer:

Blackbody radiation

Explanation:

This phenomenon described by Susan is know as black body radiation. Different materials by color reacts to incident radiation on them in diverse manner.

  • A white surface will reflect all the wavelength of light incident on it.
  • A black surface will absorb all the wavelength of light on it.

This absorption causes the black surface to be hotter compared to other surfaces.

The technetium-99 nuclide radioactively decays by beta emission. write a balanced nuclear chemical equation that describes this
nekit [7.7K]
Tc-99m<span> is a </span>metastable  isomer<span> of </span>Tc-99. It finds widespread applications in <span>medical diagnostic procedures.
</span>
Tc-99 is also a radioactive element. It's half-life is 2,11,000 years. Upon radioactive decay, it emits beta particles and gets converted into stable compound Ruthenium-99

This process of radioactive decay is shown below.
99 43Tc    →       99 44Ru     +     0 -1e
                            (stable)           (β particle)
