Mg is a chemical element that has an atomic number of 12. It can be found in many common compounds, such as the metal Mg, and the salts MgCl2 and MgSO4. The average density of mg is 1.74 g/cm3; this property makes it both heavy and dense which limits its use to some applications.

With so many uses for mg around us, it’s important to understand how heat transferred when 3.56 g of mg(s) reacts at constant pressure., The amount of heat transfer from one system to another can be calculated through Q = h∆T or Q=hΔT where q equals the energy transferred (in Joules), h equals the heat transfer coefficient (in Watts per square meter), and ∆T equals the difference in temperature between two systems. Assuming that all mg(s) atoms in a closed system would react with one another, we can calculate the amount of energy transferred as follows: Q= h∆T = ΔH/ΔS ̶ where ΔH is the enthalpy change for reaction at constant pressure and ΔS is entropy change for this type of reaction. The specific values are provided below: h has units of W·m-ˉ²K-⁻¹ an does not take into account any other factors like phase changes or chemical reactions occurring outside the boundaries of our heated system; it only considers what
