Interpretation Introduction
Interpretation:
The temperature should be calculated in ? for the given system.
Concept introduction:
The temperature for any reaction can be easily obtained using Gibb’s equation:
Where H is enthalpy, T is temperature and S is entropy of the reaction.
Further the change in enthalpy and entropy for reactions are obtained as:

How many milliliters of 97.5(±0.5) wt% H2SO4 with a density of 1.84(±0.01) g/mL will you need to prepare 2.000 L of 0.110 M H2SO4?
If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.

- In addition to the separation techniques used in this lab (magnetism, evaporation, and filtering), there are other commonly used separation techniques. Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…arrow_forwardBriefly describe a eutectic system.arrow_forward13.53 Draw all stereoisomers formed when each compound is treated with HBr in the presence of peroxides. a. b.
