What celsius temperature is needed to double the volume of a gas if the original temperature is 30 celsius? 1 -122 C
2 60 C
3 15 C
4 333 C

Explanation:

60 C

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
