compound is the temperature at which the solid is in equilibrium with its liquid. A solid compound changes to a liquid when the molecules acquire enough energy to overcome intermolecular forces holding them together in an crystalline lattice structure. The melting point range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. This data can be tabulated experimentally through multiple trials for an

5.1 Recommendation References Appendix CHAPTER ONE INTRODUCTION Drying is a thermal process which involves the final removal of volatile constituent from a substance to reduce the content of the residual liquid to an acceptable low value .Drying of a material is often the final step in a series of operation in manufacturing process‚ carried out immediately prio to packaging or dispatch. Excluding the partial drying of a solid by mechanical means (e.g centrifuges)

aqueous caustic solution containing UOP’s proprietary liquid catalyst. The caustic solution reacts with mercaptans(RSH) and extracts them. The reaction that takes place in the extractor is: 2RSH + 2 NaOH → 2NaSR + 2 H2O The second step is referred to as regeneration and it involves heating and oxidizing of the caustic solution leaving the extractor. The oxidations results in converting the extracted mercaptans to organic disulfides (RSSR) which are liquids that are water-insoluble and are then separated

Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B Agar with the exception of adding 20g of agar. These recipes were referred to later in the protocol to create additional plates and liquid cultures when growing multiple strains. King’s B Agar and Medium served as enrichment media that enhance growth

measured using a triple beam balance. Units used to measure it are grams‚ metric tons ‚ milligrams ‚ and kilograms . Volume is the amount of space enclosed by a shape or object‚ how much 3-dimensional space it occupies. It can be occupied by a solid‚ liquid or gas. The volume can be measured in cubic meters‚ cubic centimeters‚ or liters. Sometime around 250 BCE‚ the Greek mathematician Archimedes was given the task of determining whether a craftsman had defrauded the King of Syracuse by replacing

Abstract: This experiment consisted of the separation of sodium chloride and silica. The mixture was separated by extracting the sodium chloride with water and drying both substances. Adding water to the mixture‚ stirring‚ then decanting the resulting liquid twice extracts the dissolved sodium chloride from the silica. Heating both sodium chloride and silica separately provides the mass of each. The data from this experiment can be used to calculate the percent composition of sodium chloride and silica
