Hello Im siri your virtual assistants
Answer:
Explanation:
Hello there!
In this case, since this imaginary gas can be modelled as an ideal gas, we can write:
Which can be written in terms of density and molar mass as shown below:
Thus, by computing the pressure in atmospheres, the resulting density would be:
Best regards!
The net ionic equation is shorter to use and already leaves out the electrons that transferred from the reducing agent to the oxidizing agent. Also, in some occasions the aqueous ions H+ and (or) OH- ions that help balance the net ionic charge are no longer shown in the net ionic equation.
At present, most of the energy used in the united states is supplied by:

I hope this help!

Answer:
B. Electrons can exist in between energy levels
.
Explanation:
The value of energy for each energy level in an atom is quantized. Thus, electrons are not allowed to be found in between the energy levels.
When an electron absorbs energy, it becomes excited. And it would jump to a higher energy level whose energy is equal to the new energy of the electron. If the value of its new energy is less than the energy of higher levels but greater than the energy of it current energy level, the electron remains in its initial level. This is because, electrons do not exist in between energy levels
