Determine the Limiting Reactant and Reactant, and finally calculate the mass of product produced How many grams of hydrogen gas can be produced from the reaction of 50.0g Mg and 65.0 g of HCl? Mg + 2HCl =MgCl2 + H2

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.
