What restricts the flow of electrons in a circuit?

The rules of engagement (roe) working group is often used to (select all that apply.)

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
