  1. List 5 examples for each mixture classication.Solution ã Blood ã Sweat ã Salt Water ã Saliva ã  Tears Colloid   Milk   Smoke   Fog   Shaving Cream   Mayonnaise Suspension   Sandy water   Salad dressing   Orange juice with pulp ã Muddy water ã Oil and water 2. What are the properties of a solution? Properties are same throughout composed o! solvent solute !orm when particles separate and are surrounded #y solven can #e any state o! matter ionic solutions use ionic compounds $%aCl& '(O) to allow *ow o! electricity 3. What are the properties of a colloid? Contains undissolved particles that are not settled out& scatters a #eam o! light 4. What are the properties of a suspension? Particles are easily seen and separated out& properties are not the same throughout 5. What is the dierence et!een homo eneous and hetero eneous mixtures? 'omogeneous+ can,t see individual parts'eterogeneous+ can see individual parts #. What is a pure sustance?  Single kind o! matter that has a speci-c composition $. %o! are most elements found in nature? .n compounds or mi/tures &. What are the four methods to separate a mixture? 0istillation+ separates li1uids !rom li1uids $#oiling points)Filtration+ separates solids !rom li1uids2vaporation+ separates solids !rom li1uids $salt water)Magnetic 3ttraction+ seperates iron !rom other compounds '. What is the dierence et!een solutes and sol(ents? Solvent+ part o! mi/ture in greatest 1uantitySolute+ parts dissolved in the solvent 1). What is a solute*s eect on a sol(ent? 4aises #oiling point lowers !ree5ing point 11. What is the +uni(ersal+ sol(ent? Water 12. What solutes allo! electricit, to -o!? .onic 13. What is the dierence et!een a dilute and a concentrated solution? 0ilute+ only a little solute is dissolved in the solvent more solute can #e dissolvedConcentrated+ a lot o! solute is dissolved in the solvent 14. What is soluilit,? Measure o! how much solute can #e added to a solvent 15. What are the 3 factors that aect soluilit,? Pressure& temperature& type o! solvent 1#. What are the units of measurement for soluilit,? 677 grams o! 8888 in (7 degrees Celsius  1$. What is the relationship et!een pressure and soluilit,? 0irectly proportional solu#ility increases as pressure increases 1&. What is the relationship et!een temperature and soluilit,? .n solids& directly proportional9 Solu#ility increases as temperature increases.n gaseous solutes& inversely proportional9 Solu#ility decreases as temperature increases 1'. %o! do polar solutes interact !ith nonpolar sol(ents? %on+polar solutes do not dissolve in polar solvents 2). %o! do nonpolar solutes interact !ith nonpolar sol(ents? Mi/ well with each other 21. Wh, does oil -oat on !ater? /2 reasons0 69Water is polar& while oil is non+polar& so they,re insolu#le(9Oil is less dense
