draw the lewis structure, including unshared pairs, of the following molecule. carbon has four bonds in the compound. propane (c
1 answer:
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.

Answer:- 1.90 atm
Solution:- It is based on combined gas law equation, PV = nRT
In this equation, P is pressure, V is volume, n is moles of gas, R is universal gas constant and T is kelvin temperature.
If we divide both sides by V then:
We know that, molarity is moles per liter. So, in the above equation we could replace by molarity, M of the gas. The equation becomes:
P = MRT
T = 20 + 273 = 293 K
M =
Let's plug in the values in the equation:
P =
P = 1.90 atm
So, the pressure of the gas is 1.90 atm.
