Conceptual Chemistry Chapter 2 Test

The first 15 slides your job once again is to use the periodic table to get the answers. Good luck!

1. This element has 42 protons.

2. This element has an atomic mass of 16 (rounded).

3. This element is an alkali metal in period 3.

4. This element is in the actinide series and in the 5th group from the left.

5. This element has an atomic number of 54.

6. This element is in the Lanthanide series in the 2nd

group from the left.

7. This element has an atomic mass of 12 (rounded).

8. This element is an Alkaline Earth metal in period 6.

9. This element is in the Boron Group and period 5.

10. The element is in the Halogen group and in period 2.

11. The element is in the Noble Gas group and in period 2.

12. This element is a Transition Metal in the 3rd

group from the left and in period 6.

13. This element is in the Oxygen Group and in period 5.

14. This element is in the Nitrogen Group and in period 6.

15. This element is in the Carbon Group and in period 4.

Students in the chemistry lab pick up various items, and their job is to classify each of the items. In the next 5 slides, your job is to determine what each student would correctly think.

Let’s see. Cobalt Chloride + Water.

This must be classified as ….

Mike picks up a beaker of water and Cobalt Chloride.

Titanium is easy. This must be

classified as ….

Braeden picks up a bar of titanium.

Maybe if it get this one correct, Mr. Korzan will

let me have a piece. This must be classified

as ….

Wesley gets hungry and picks up a lemon meringue pie..

Let’s see. Magnesium

Carbonate. This must be classified

as ….

Bryanna decides to look at some magnesium carbonate.

I can do this one for sure. This must be

classified as ….

Sean picks up a beaker with isopropyl alcohol and water.

The next five slides, your job is to classify the product of each reaction and also determine if the reaction is chemical or physical.

Audrey is going to mix sodium chromate, which is a clear liquid, with lead nitrate, which is another clear liquid. The picture below shows what happens.

According to the picture, classify the contents of the beaker after Audrey mixes the two solutions. Then determine if the reaction is a chemical reaction or a physical reaction.

Kaily is going to mix sodium carbonate, which is a clear liquid, with hydrochloric acid, which is another clear liquid. The picture below shows what happens.

According to the picture, classify the contents of the beaker after Kaily mixes the two solutions. Then determine if the reaction is a chemical reaction or a physical reaction.

Bubbles

Caitlyn takes a tea bag and places it in a glass with hot water. The picture below shows what happens.

According to the picture, classify the contents of the glass after Caitlyn adds the tea bag. Then determine if the reaction is a chemical reaction or a physical reaction.

James is going to mix copper sulfate, which is a blue powder, with water. The picture below shows what happens.

According to the picture, classify the contents of the beaker after James mixes the powder with the water. Then determine if the reaction is a chemical reaction or a physical reaction.

Aaron is going to mix sodium metal, which is a silver solid, with water. The picture below shows what happens.

According to the picture, classify the contents of the beaker after Aaron mixes the sodium with the water. Then determine if the reaction is a chemical reaction or a physical reaction.

The next five slides all you have to do is determine if they are physical properties or chemical properties of matter.

Potassium permanganate is a purple crystal.

Is this a physical property or a chemical property?

Sulfuric acid reacts with metal to produce hydrogen gas.

Is this a physical property or a chemical property?

Sodium Chloride has a cubic crystal.

Is this a physical property or a chemical property?

Sodium metal reacts with water to produce hydrogen gas.

Is this a physical property or a chemical property?

Sodium metal is soft and can be cut with a knife.

Is this a physical property or a chemical property?
