Chem 101 Lab Report 2 Essay

2016-3-20 · Chem 101 Lab Report 2. Mixtures are made up of substances or components. If the mixture is fairly uniform in composition, properties, and its overall appearance, it is homogenous. If the component parts are clearly separated, it is heterogeneous. In order to identify the components in a mixture, methods must be used to sort out the components.

Drying agents

2016-3-21 · The Gibbs free energy for the following reaction Na 2 SO 4 + 10 H 2 O ---- > Na 2 SO 4 * 10 H 2 O can be described by ΔG = ΔH - TDS = -77.8 kJ/mol - T (-261 J/mol*K) Based on this equation, it can be estimated that the reaction reverses at 298 K or 25 o C (ΔG =0). The drying process itself is slightly exothermic (ΔH for the process is negative) but the entropy decreases during the drying ...
