Chemistry 1

Front 1

What is matter?

Back 1

Anything that has mass and volume and takes up space. Matter can push and create pressure.

Front 2

Example of matter

Back 2

Rock is matter since you put it in water and water rises

Front 3

Example of non-matter

Back 3

Heat is not matter since it has no weight. Air is on the periodic table with mass.

Front 4

How would you typically measure the amount of a solid?

Back 4

Scale or triple beam balance.

Front 5

What are you measuring with a solid and with what unit?

Back 5

Mass in grams

Front 6

How would you typically measure the amount of a liquid?

Back 6

Graduated cylinder

Front 7

What are you measuring with a liquid and with what unit?

Back 7

Volume in mL

Front 8

A marble has a volume of 20 ml. It also has a mass of 10G. What is the density?

Back 8

D=M/V=10/20=0.5 g/ml

Front 9

The density of aluminum is 2.7 g/ml. If the aluminum has a volume of 20 ml, what is the mass?

Back 9

D=M/V 2.7=M/20 54=M 54g

Front 10

A rock has a density of 8g/ml. If the rock’s mass is 2g, what is the rock’s volume?

Back 10

D=M/V 8=2/V 0.25 = V 0.25 ml

Front 11

Name the two parts of any solution

Back 11

solvent and solute

Front 12

Explain the two parts of a solution and give examples

Back 12

solvent is the bigger one if both are in same phase. Solvent does dissolving. Water is solvent to salt being solute

Front 13

What are two solutes in Coke?

Back 13

Carbon dioxide and sugar

Front 14

If two substances are in the same state of matter (i.e., solid, liquid, gas) and are dissolved in one another, such as oxygen and nitrogen in the air, which is the solvent and which is the solute?

Back 14

Oxygen is the solute and nitrogen is solvent. Nitrogen is 78% so there is less oxygen.

Back 23

Physical because it is still water and it just goes through a phase change.

Front 24

I drop a bottle of perfume and it breaks. I can smell the perfume. Is this chemical or physical and why?

Back 24

Physical because perfume already smelled in the bottle. It was only broken.

Front 25

I drive my car in the winter and the salt on the road causes rust. Is this chemical or physical and why?

Back 25

Chemical because rust is a precipitate and changes color.

Front 26

I pour two clear, colorless liquids together and a white solid is produced. Chemical or physical and why?

Back 26

Chemical because the white solid is a precipitate and the color changes pouring of liquid is physical change.

Homogeneous when it has no fruit in it and is just a box you buy at the store.

Front 36

Is dry ice (frozen CO2) an element, compound, homogenous mixture or heterogeneous mixture and why?

Back 36

Compound because it is two elements combined – carbon and oxygen

Front 37

Is diamond an element, compound, homogenous mixture or heterogeneous mixture and why?

Back 37

Element because I is pure carbon unless it has impurities and then it is heterogeneous

Back 69

Suspensions

Front 70

Suspensions

Back 70

particles can be filtered out with filter paper and they will settle out by gravity; particles will also scatter light shined through the mixture so the beam can be seen

Front 71

Suspension example

Back 71

muddy water/sand in water

Front 72

Colloid

Back 72

particles are smaller and can’t be filtered nor do they settle out, but they are still big enough to scatter a beam of light

Front 73
