A 110.0-g sample of metal at 82.00°C is added to 110.0 g of H O(l) at 27.00°C in an insulated container. The temperature rises to 30.56°C. Neglecting the heat capacity of the container, what is the specific heat of the metal? The specific heat of H O(l) is 4.18 J/(g ∙ °C).

Explanation:

The heat rejected by the sample is equal to the heat received by the water. Then:

The specific heat of the sample is:

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.
