SIZIF [17.4K]

There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:

Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.

It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.

Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.

To know more about Lewis structure.

Why do you elements in the same group have similar properties
lozanna [386]

Answer:

They have similar properties, because they share similar amounts of electrons in their outer shell, valence electrons! This means they will only be able to interact with other elements with those electrons so they often show similar properties.

Calculate the hydrogen-ion concentration (H+] for the aqueous solution in which [OH-1 is 1 x 10-12 mol/L.
Artemon [7]

Answer:If we have [H+][OH-]= Kw = 1.0 x 10^-14

Then [H+]= Kw/ [OH-]= 1.0x 10^-14/ 1 x 10^-11 =1 x 10^-3 mol/L

And here is the solution - as you can see it is an acidic one :

pH = - log [H+]= - log 1 x 10^-3 = 3 < 7
