The reaction mentioned in the question is a decomposition reaction.

Explanation:

Decomposition reaction is a specific type of chemical reaction in which the reactant molecule undergo break down to generate its respective products.

 NaCl ⇒ Na + Cl2

In the above reaction sodium chloride(NaCl) undergo decomposition or break down to generate Sodium(Na) and chlorine gas(Cl2).

It is Synthesis and combustion

got it correct on EDGE 2020

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.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
