A. 15 grams

A: B: 100 grams 4 grams

#4Mass of jar at start 52 gMass of jar at end 48 g

How much salt was added to a test tube of water in this lab when trying to make a solution?

C: D:2.2 grams 9 grams

B. 4 grams

A: B:The solution would be

transparentIt would be thick

#5How would the students in the previous lab know

that the solution was saturated?

C: D:Add more salt and it would dissolve

They could see salt at the bottom of the tube

D. They could see salt at the bottom of the tube.

A: B:Heat it Freeze it and mass it

#6How do we find the solubility of a

certain substance in a certain solvent?

C: D:

See how much dissolves in the solvent before it is saturated.

Filter it and measure

the filtrate.

C. See how much dissolves in the solvent before it is saturated.

(This would be approximate.)

A: B:The ink is insoluble in water.

The process was not

done correctly.

#7On a chromatogram, a dot of ink did not

change at all when placed in water.What can you conclude?

C: D:It is made of only one

Substance.

The dot was too large.

A. The ink is insoluble in

water.

A: B:Two did not reactAll markers have at least one of the same

dyes in them.

#8A dot of blue, orange, purple and red marker

were placed on a chromatogram. Although the shapes of the ink were different, how could the

forensic scientist know 2 of the markers containedsome of the same EXACT dye.

C: D:Two disappeared from

the paper completely.

One small part of the chromatogram of 2 inks looked the same.

D. One small

part of the 2 chromatograms

looked the same.

A: B:The temperature falls, more water freezes.

Temperature rises, ice melts.

#9If I add salt to ice, which of the following

would probably happen?

C: D:Temperature falls, ice melts.

Temperature stays the

same, ice melts.

C. Temperature falls and ice

melts.

A: B:101 F 100 C

following is probably the temperatureof the boiling solution?

C: D:200 C 104 C

D.

104 C

A: B:Water evaporates Water dissolves

#11Which of the following occurs

when salt water is boiled?

C: D:Water dries Salt disappears

A.Water

evaporates

A: B:Obvious mixtures All solutes

nothing behind.

C: D:Cloudy liquids Solutions

A: B:Filtrate Residue

#13Zinc oxide and water when filtered,

left behind a white powder in the filterand just the water in the test tube. What is the

white powder in the filter called?

C: D:Solution Solute

B. Residue

A: B:It looks like white sugar.

It is a white crystalline solid that is soluble in water and non-magnetic

#14Which of the following is a good observation

of the properties of a substance?

C: D:It is crystalsIt looks like either sugar or salt because it is white and solid.

B. It is a white crystalline solid that is soluble in water and non-magnetic

A: B:Melting/freezing point Density

#15Which of the following is NOT a

Characteristic property of matter?

C: D:Mass Solubility

C.

MASS!!!!
