100
Matter that contains only one kind of particle.
Pure Substance
100
The larger part of a solution, the part into which the solutes dissolve
Solvent
100
What is Sorting?
Physically separating large pieces of a mechanical mixture so that similar pieces are together
100
When looking at a picture how do a mechanical mixture and a solution differ?
100
When there is not very much of a solute dissolved in a solution it is called?
Dilute
200
Matter that contains two or more pure substances mixed together
Mixture
200
The smaller part of a solution, the part of a solution that dissolves the solvent
Solute
200
What is Floating?
A separation technique in which the ligher component rises to the top of a liquid
200
Give an example from class of a solute that did dissolve well in water.
Salt & or Sugar.
200
Which method would you use to remove oil from a mechanical mixture. How does this connect to an oil spill.
Floating.
When cleaning up an oil spill, they use floating booms and skimmers to collect the oil on top of the ocean.
300
A mixture with different parts that you can see
Mechanical Mixture
300
The amount of solute present in an amount of solution
Concentration
300
What is settling?
A separation technique in which the heavier component sinks to the bottom of a liquid
300
Give an example of a solute that does not dissolve in water?
Cooking Oil.
300
What is the most common solvent on earth?
Water
400
A mixture that looks like a single pure substance; a uniform mixture of two or more pure substances
A Solution
400
Able to dissolve in a specified solvent
Soluable
400
What is a sieve?
A device used to separate the components of a mixture, with many visible holes that allow smaller solids and liquids to pass through
400
When no more epsom salts would dissolve into our solution - it is called....
A saturated solution
400
What method would you use to separate salt from water?
Boil it so that the water all evaporates and you are only left with the salt.
500
To mix one type of matter into another type of matter to form a solution
Dissolve
500
Not able to dissolve in a specified solvent
Insoluable
500
What is a Filter?
A device with many small holes that trap solid pieces of a mixture but allow liquids and gases to pass through
500
What is the formula for the concentration of a solution?
Concentration formula = mass of solute/100 ml of a solution
500
Connect your separating mechanical mixtures lab to how hard it is to clean up an oil spill.
When oil is spilt it is very very difficult to completely clean everything and remove oil from the wildlife... kind of like how we couldn't clean all the seeds etc. during our experiment.
