In a technical sense, a server is an instance of a computer program that accepts and responds to requests made by another program, known as a client. Less formally, any device that runs server software could be considered a server as well. Servers are used to manage network resources.
Diamond is stable at extreme pressures. To the top Conclusion Metamorphic rocks form from heat and pressure. Some of the minerals that make up those rocks also change properties as heat and pressure is applied. Polymorphs of minerals at different phases result and thus some minerals are only found in metamorphic rocks.ome of the minerals that make up those rocks also change properties as heat and pressure is applied.

Introduction Heat of formation is the enthalpy change when one mole of product is formed from its constituent elements under standard conditions. The equation for the formation of calcium carbonate from its elements under standard conditions is Ca(s)+C (graphite)+O2 (g) CaCO3(s).HfO (CO2 (g)) = -393.5 kJ mol -1 ?HfO (H2O (l)) = -285.5 kJ mol -1 Heat of formation of calcium carbonate = ?H1 + ?Hf (CO2 (g)) +?Hf (H2O (l))- ?H2 = -421+(-393.5)+(-285.5)- (-17.6) = -1082.4 kJ mol -1 In order to achieve the answer, Hess's law is used.
