Explain why HCl can be a strong electrolyte, but a dilute HCl solution can be a poor conductor?
zloy xaker [14]

Answer:

Because as the concentration is diminished, the capacity to transfer electricity is diminished as well.

Explanation:

Hello!

In this case, since electrolytes are substances that are able to conduct the electricity in aqueous media (solutions in which water is the the solvent) because they have the capacity to form ions with both positive and negative charges, due to the fact that HCl is a strong acid, we notice it is fully ionized in solution and therefore it is a strong electrolyte. However, when the concentration is diminished, we can notice that strength is diminished as well because less ions will have the capacity to transfer the electricity and therefore it'd become a poor conductor or weak electrolyte.

Best regards!

A series of experiments investigating the reaction of (CH3)3CCl with H2O to create (CH3)3OH produces a plot of Ln[(CH3)3CCl] vs.
Helga [31]

Explanation:

There will occur a straight line for the curve of Ln[(CH_{3})_{3}CCl] Vs. time. Since, it is a first order reaction therefore, the formula of its half-life will be as follows.

         Half-life = \frac{ln 2}{k}

or,         k = \frac{ln 2}{t_{\frac{1}{2}}}

               = \frac{ln 2}{220} sec^{-1}

So, rate of the reaction will be as follows.

          Rate = [(CH_{3})_{3}CCl]^{1}

                   = \frac{ln 2}{220} sec^{-1} \times 0.15 M

                   = 0.000473 Ms^{-1}

                   = 4.73 \times 10^{-4} Ms^{-1}

Thus, we can conclude that the instantaneous rate of given reaction is  4.73 \times 10^{-4} Ms^{-1}.

How many unpaired electrons are present in a lithium atom?.
Cerrena [4.2K]
  • Lithium has Z =3

Electronic configuration is given by

\\ \tt\bull\rightarrowtail 1s^22s^1

  • 1s orbital is filled
  • 2s orbital is unfilled

So

  • unpaired electrons=1

What would the wave speed be of a wave with a frequency of 64Hz and a wavelength of 102m
masya89 [10]

Answer: The speed of a wave with a frequency of 64 Hz and a wavelength of 102m is 6528 m/s.

Explanation:

The formula of a speed of a wave is frequency x the wavelength.

Therefore multiply 64 and 102.

You get 6528 m/s which is the correct answer.
