True or False When the attraction between the particles overcomes their motion the particles clump together to boil. ​

Answer:

False

Explanation:

It is wrong to claim that when the attraction between particles overcomes their motion, the particles will clump together to boil.

During boiling particles do no clump together, they tend to move apart more rapidly.

  • Boiling occurs when the vapor pressure overcomes the ambient atmospheric pressure.
  • The hotter part of the boiler close the heat source moves rapidly away because they have become less dense.
  • The colder and denser part sinks and this interaction sets up a convection cell.

Explain the structure of an atom. Make sure to include the charges of the subatomic particles.
Ber [7]

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus of the atom contains the protons and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged)

Calculate the pH of the cathode compartment solution if the cell emf at 298 K is measured to be 0.660 V when (Zn^2+)=0.22 M and(
yaroslaw [1]

Answer:

pH = 2.059

Explanation:

At the Cathode:

The reduction reaction is:

2H^+ + 2e^- \to H_2   \ \ \ \mathbf{E^0_{red}= 0.00 \ V}

At the anode:

At oxidation reaction is:

Zn \to Zn^{2+} +2e^-   \ \ \ \mathbf{E^0_{ox} = 0.76 \ V}

The overall equation for the reaction is:

\mathbf{Zn + 2H^+ \to Zn^{2+} + H_2}

The overall cell potential is:

\mathbf{E^0_{cell}= E^0_{ox} + E^0_{red}}

\mathbf{E^0_{cell}= 0.76 \ V +0.00 \ V}

\mathbf{E^0_{cell}= 0.76\ V}

Using the formula for the Nernst equation:

E = E^0 - ( \dfrac{0.0591}{n})log (Q)\\

where;

E = 0.66

(Zn^2+)=0.22 M

Then

0.66 =0.76- ( \dfrac{0.0591}{2})log \bigg ( \dfrac{[Zn^{2+} ] PH_2}{[H^+]^2} \bigg )

0.66 =0.76- 0.02955 * log \bigg ( \dfrac{0.22*0.87}{[H^+]^2} \bigg )

3.4 = log ( 0.1914) - 2 log [H⁺]

3.4 = -0.7180 - 2 log [H⁺]

3.4 + 0.7180 = - 2 log  [H⁺]

4.118  = - 2  log  [H⁺]

pH = log [H⁺] = 4.118/2

pH = 2.059
