Mixtures are made of only 2 things. True or False

False

In all mixtures individual parts can be seen.

False, you cannot see them in solutions.

AFTER I DISSOLVED SOME SOLUTE IN A SOLVENT I NOTICED THAT NO MORE WOULD DISSOLVE.  HOW COULD I DETERMINE IF I HAVE A SATURATED SOLUTION?

YOU COULD ADD MORE SOLVENT TO SEE IF YOU COULD GET THE REST OF THE SOLUTE TO DISSOLVE.

WHAT ARE FOUR METRIC UNITS FOR VOLUME?

LITERS, MILLILITERS, DECALITERS, CENTILITERS, HECTOLITERS, KILOLITERS, DECILITERS

NAME GIVEN TO SOLUTES THAT CAN BE DISSOLVED.

SOLUBLE

Solutions are examples of mixtures. T/F

True

Solutions cannot be separated back into original parts.T/F

False, using evaporation they can be separated.

WHAT WOULD BE THE FIRST STEP IN MEASURING HOW MUCH DISSOLVED SALT IS IN A SOLUTION?

FILTER OUT THE UNDISSOLVED SALT.

WHEN A SOLUTION HAS DISSOLVED ALL THE SOLUTE IT CAN IT IS CALLED A ....

SATURATE SOLUTION

Give all the special characteristics of a solution. There should be 4. If you get 3 out of the 4 you get all points.

dissolving, solvent and solute, evaporation, cannot see individual parts

Dissolving a solute makes the mass of a solvent increase? True//False

true

If I add 25 grams of solute to a solvent how much does the mass of the solution increase?

by 25 grams

I made a solution by putting 30 grams of solute into the solvent. I evaporated the solvent in a solution. How much solute will be left?

30 grams

State all the evidence something has to have to be called a mixture? If you get 2 out of 3 you get the points.

made of two or more substances, can be separated back into separate substances, can see individual parts

I combine a solute and a solvent. After stirring the solute is at the bottom of the solvent. Have I made a mixture and a solution or both?

No, just a mixture was made.

Give two things beyond having 2 or more substances and being able to separated that solutions have to make them special mixtures.

dissolving, cannot see individual parts

I add pepper to water. The pepper stays on the top of the water even after stirring. Is this a mixture, solution or both?

It is just a mixture.

NAME GIVEN TO SOLUTES THAT CANNOT BE DISSOLVED.

INSOLUBLE

We we put 80 ml. of water together with 10 grams of salt, how much does the solution weigh?

90 grams

These solutions were compared for concentration. Which is more concentrated? Explain 

solution 1 - 50 ml. of water 15 grams of sand solution 2 - 50 ml. of water and 10 grams of sand

Neither is more concentrated because they are not solutions. Sand and water will not make a solution.

GIVE ME 4 METRIC UNITS FOR MASS.

GRAMS, MILLIGRAMS, DECAGRAMS, CENTIGRAMS, HECTOGRAMS, KILOGRAMS, DECIGRAMS

SUE MIXED TOGETHER 7O ML OF SOLVENT AND SOME SOLUTE.  IT CREATED A SOLUTION.  SAM MIXED TOGETHER 60 ML OF THE SAME SOLVENT AND SOME  SOLUTE.  WHEN HE PLACED THEM ON A BALANCE THEY FOUND THAT SUE'S WAS MORE CONCENTRATED.  IS THAT TRUE? EXPLAIN

 WE DO NOT KNOW BECAUSE THEY DID NOT COMPARE EQUAL AMOUNTS OF THE EACH SOLUTION.

A _______________________ looks the same throughout.

 solution

If you mix a solute and solvent together and let it sit for a few minutes, what evidence would there be that it is just a mixture and not a solution? 2 ANSWERS NEEDED

The solute would be floating or go to the bottom of the cup or you could see the individual parts. No dissolving would have occurred.  

A student adds 3 scoops of solute to 50 grams of solvent.  The solute dissolves.  One scoop of the solute equals 10 grams.  What does the solution weigh?

80 grams
