Mixtures-True/False | ||
#1 | Mixtures are made of only 2 things. True or False |
False |
#2 | In all mixtures individual parts can be seen. |
False, you cannot see them in solutions. |
#3 | 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. |
#4 | WHAT ARE FOUR METRIC UNITS FOR VOLUME? |
LITERS, MILLILITERS, DECALITERS, CENTILITERS, HECTOLITERS, KILOLITERS, DECILITERS |
#5 | NAME GIVEN TO SOLUTES THAT CAN BE DISSOLVED. |
SOLUBLE |
Solutions | ||
#1 | Solutions are examples of mixtures. T/F |
True |
#2 | Solutions cannot be separated back into original parts.T/F |
False, using evaporation they can be separated. |
#3 | WHAT WOULD BE THE FIRST STEP IN MEASURING HOW MUCH DISSOLVED SALT IS IN A SOLUTION? |
FILTER OUT THE UNDISSOLVED SALT. |
#4 | WHEN A SOLUTION HAS DISSOLVED ALL THE SOLUTE IT CAN IT IS CALLED A .... |
SATURATE SOLUTION |
#5 | 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 |
Mixtures and Solutions | ||
#1 | Dissolving a solute makes the mass of a solvent increase? True//False |
true |
#2 | If I add 25 grams of solute to a solvent how much does the mass of the solution increase? |
by 25 grams |
#3 | 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 |
#4 | 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 |
#5 | 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. |
Mixtures and Solutions 2 | ||
#1 | 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 |
#2 | 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. |
#3 | NAME GIVEN TO SOLUTES THAT CANNOT BE DISSOLVED. |
INSOLUBLE |
#4 | We we put 80 ml. of water together with 10 grams of salt, how much does the solution weigh? |
90 grams |
#5 | 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. |
solutions | ||
#1 | GIVE ME 4 METRIC UNITS FOR MASS. |
GRAMS, MILLIGRAMS, DECAGRAMS, CENTIGRAMS, HECTOGRAMS, KILOGRAMS, DECIGRAMS |
#2 | 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.
|
#3 | A _______________________ looks the same throughout. |
solution
|
#4 | 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. |
#5 | 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 |
