I Introduction Heat transfer controlled by the evaporation of liquids on solid substrates is the subject of many experiments and numerical analyses 14 On the other hand most industrial coating. YOUR TASK Aim to make a salt solution then try to get the salt back Copy down your aim in your science books 1 Predict what will happen when you evaporate a salt solution When a salt solution is evaporated I think 2 Make a salt solution use the Alkanes, alkenes, alkynes and aromatics. Types of Hydrocarbons. Hydrocarbons contain C and H. There are 4 families, alk. anes. only have C-C single bonds, alk. enes. have at least one C=C and alk. ynes. what is . homegeneous. ?. What is solute ?. Uniformly mixed – only see one layer. substance that dissolve in a solvent. What is solvent?. Is a substance that dissolves the solute. What is solution ?. Grade 7 Science. Separating . M. ixtures and Solutions. What are the three solids and the liquid in the picture below?. White, yellow and brown sugar. Molasses . Many products depend on technology for separating mixtures and solutions. Mixtures may be separated by many different techniques based on differing physical and/or chemical properties. Sorting. Simply picking apart the different components. This can be easy and obvious…. August 31. How do you separate?. How can you separate mixtures?. Separating. Separating is based on the difference in . physical properties . of the substances…. Think about how you would separate a bag of m&ms. Ian Harrison. Dept. of Chemistry, . UVa. Charlottesville, VA.

Cannot be broken down and retain its properties.. Has a fixed composition.. Every sample of a pure substance has EXACTLY the same composition AND exactly the same characteristics - homogeneous. Chapter 5. Ex:. Melting. Freezing. Boiling/evaporation. Condensation. Sublimation. Dissolving. Bending. Crushing. Breaking. Chopping. Filtration. distillation. Physical change. Does not make a different substance. Introduction. Alkanes are saturated hydrocarbon, that is they contain only . carbon-hydrogen. (C-H) and . carbon-carbon. (C-C) single bonds. The general formula of alkane = C. n. H. 2n+2 . Where n is the number of carbon. How can matter be classified?.
