    18. 18. Compounds always contain two or more elements joined in a fixed proportion water
    19. 19. The properties of mixtures can vary because the composition is not fixedMixtures can be classified by howwell the parts of the mixture are distributed throughout the mixture.
    20. 20. Heterogenous MixturesThe parts of the mixture are noticeably different from one another. Homogenous Mixtures Substances are so evenly distributed that it is difficult to distinguish one substance in the mixture from another

    28. 28. Mixtures can be classifed as a solution, a suspension or a colloid based upon the size of its largest particle. Solution Suspension Colloids• Light passes through • Heterogeneous mixture • Particles intermediate in size• Particles to small to settle out • Scatters light, cloudy • Do not seperate into layers• Particles cannot be filtered • Particles can be filtered • Cannot use a filter to seperate parts

    45. 45. Separation by Filtration Can you imagine theIn filtration: insoluable solid (trapped in filter) = residue implications of an industrial fluids (passes through filter) = filtrate filter that could be used in a process for more than 70 years without being replaced? Filtration with a piece of filter paper The typical kidney filters approximately 180 liters of plasma per day and each of the 3 liters of plasma gets filtered about 60 times. To replace this much water you would have to drink a 12 oz. soft drink every 3 minutes of the day;fortunately 99% of the filtrate gets reabsorbed, leaving 1.5-2 liters of urine per day. This is an incredible amount of filtration that is performed very day.
    46. 46. Separation by Distillation Distillation uses heat to purify or separate mixtures containing one or more liquids. As a mixture is heated, the liquid with the lowest boiling point will boil and turn to vapor leaving behind any solid material or other liquids. When fruit and plant materials ferment, a dilute version of ethyl alcohol is produced. Distilling the fermented material purifies and concentrates the ethanol. A variety of other components, such as water, esters and other types of alcohol, are also collected during the distillation process, which One of the earliest uses of distilling was to make perfume, accounts for the unique flavor of each alcoholicwhich began around 3500 B.C. The aroma from various plants spirit.and herbs is contained in what are known as essential oils, whichcan be extracted through distillation. However, many aromaticplants tend to decompose at high temperatures so separation by The vapor is captured and coolednormal distillation isnt practical. In those instances, steam is until it condenses, resulting in apassed through the plant material to draw out the essential oilswithout burning the mixture. The steam is then captured and purified version of the liquidcondensed just as in normal distillation.
    47. 47. Chemical PropertiesAny of a material’s properties thatbecomes evident during a chemical reaction. Evidence that a chemical change has occurred: • change in color • production of a gas • formation of a precipitate
    48. 48. How easily something will burn or ignite, causing fire or combustion Degrees of Flammability• Materials that will not burn.• Materials that must be pre-heatedbefore they will ignite.• Materials that must be moderately heatedbefore they will ignite.• Liquids and solids that can ignite under alltemperature conditions.• Materials which will rapidly vaporize atatmospheric pressure and normal temperature.

Flammability How easily something will burn or ignite, causing fire or combustion Degrees of Flammability• Materials that will not burn.• Materials that must be pre-heatedbefore they will ignite.• Materials that must be moderately heatedbefore they will ignite.• Liquids and solids that can ignite under alltemperature conditions.• Materials which will rapidly vaporize atatmospheric pressure and normal temperature.
    50. 50. The property that describes how readilyReactivity a substance combines chemically with other substances When oxygen reacts with iron and water, rust forms Oxygen is a highly reactive element
    51. 51. Review Questions1. Why can the properties of a mixture vary?2. What processes are used to separate mixtures?3. What are some examples of physical properties?4. What is the difference between a physical andchemical change?5. What are common types of evidence for a chemicalchange?
