Two carbon atoms cannot be linked to each other by more than three covalent bonds why

Leto [7]

Answer:since,there is a single bond between the two carbon atoms and both share their one atom therefore for completing its shell it need to combine with three atoms of carbon or other element . therefore it cannot be linked to more than 3 covalent bonds since its shell will be completed to become stable .

4.8 moles of Kl are dissolved in 850 mL of water. What is the molarity of the solutions?

AURORKA [14]

Hey there!

Molarity = 4.8/850 x 1000 =5.647mol/lit or 5.65M

Hope this helps you dear :)
Have a good day :)

Enter your answer in the provided box. what is the emf of a cell consisting of a pb2 / pb half-cell and a pt / h / h2 half-cell

sp2606 [1]

Answer:

The emf of the electrochemical cell has been calculated to be 3.364.

in order to calculate the emf we need to apply Nernst equation.

The emf has been the potential of the cell in the reaction with the change in the electrons in the reaction. The emf of the cell has been given by the Nernst equation as -

emf= E⁰ cell - 0.059/n. log 1/concentration

Computation for the emf of the cell

The given cell has the number of electrons transfer, n= 2

The concentration of Pb2= 0.57 M

The concentration of H= 0.090 M

The cell potential of the reaction has been= -0.126

Substituting the values for the emf of the cell:

emf= -0.126- 0.059/2 * log 1/ [0.57]x [0.090] ²

emf= 1.555* 2.337

emf=3.634 v

The emf of the electrochemical cell has been calculated to be 3.634 v.

Photochemical smong result from the interaction of pollution in the presence of

Goshia [24]

Photochemical smong result from the interaction of pollution in the presence of sunlight. The photochemical smog is result of the chemical reaction in the air between the sunlight, nitrogen oxides and volatile organic compounds.
It is noticed as a brown haze above cities. The negative effects are: production of chlorofluorocarbons (CFCs) increased UV radiation, irritation to the eyes, nose, and throat.
