Metals and Non metals, - Reactivity Series

Question 1

Name me all of the properties of metal.

Answer 1

They:
-are lustrous (shiny)
-are hard and strong
-have a high density
-are malleable (can be bent and pressed into different shapes) and ductile (can be drawn into wires).
-are good conductors of electricity
-have high melting and melting points (except mercury, which is liquid at room temperature).

Question 2

What does it mean to say that a metal is Sonorous?

Answer 2

When the metals are hit they make a ringing sound like a bell- they do not make a dull thud.

Question 3

How does reactivity affect extraction?

Answer 3

-Metals above carbon on the reactivity series must be extracted using electrolysis. Electrolysis can also be used to purify copper.
-Metals less reactive than carbon can be extracted from their ores by reduction using carbon, smoke or charcoal.
-Platinum, gold, silver and copper can occur native and does not need to be extracted.

Question 4

What is reduction?

Answer 4

The gain of electrons by a substance.

Question 5

What is electrolysis?

Answer 5

The process of breaking apart an ionic compound using
electricity.

Question 6

Say the list of metals from very reactive to very unreactive?

Answer 6

Lithium, Potassium, Barium, Calcium, Sodium, Magnesium, Aluminium, Carbon, Zinc, Iron, Nickel, Tin, Lead, Hydrogen, Copper, Mercury, Silver, Gold, Platinum.

Question 7

List the metals which react with oxygen.

Answer 7

Lithium, Potassium, Barium, Calcium, Sodium, Magnesium, Aluminium, Carbon, Zinc, Iron, Nickel, Tin, Lead, Hydrogen, Copper, Mercury, Silver.

Question 8

List the metals which react with Dilute Acids.

Answer 8

Lithium, Potassium, Barium, Calcium, Sodium, Magnesium, Aluminium, Carbon, Zinc, Iron, Nickel, Tin, Lead.

Question 9

List the metals which react with water.

Answer 9

Lithium, Potassium, Barium, Calcium, Sodium.

Question 10

Copper+ Sulphate+ Iron–>

Answer 10

–> Iron Sulphate+ Copper.

Question 11

What happens when a piece of magnesium is dipped into blue copper sulfate solution?

Answer 11

-The blue colour fades as colourless magnesium sulfate solution forms.
-Brown copper coats the surface of the magnesium.

Question 12

What does
magnesium+ copper sulfate–>?

Answer 12

–> Magnesium sulfate+ copper.

Question 12

What is magnesium+ copper sulfate–> Magnesium sulfate+ copper as a symbol equation?

Answer 12

Mg+ CuSo4–> MgSo4+ Cu

Question 13

What is the general formula for metals reacting with oxygen?

Answer 13

metal+ oxygen–> metal oxide
e.g.
magnesium+ oxygen–> magnesium oxide
2Mg+ O2–> 2MgO

Question 14

What is the general formula for metals reacting with water?

Answer 14

metal+ water–> metal hydroxide+ Hydrogen.
e.g.
potassium+ water–> potassium hydroxide+ Hydrogen.

Question 15

What is the general formula for metals reacting with acid?

Answer 15

Metal+ acid–> Salt+ Hydrogen
e.g.
Magnesium+ HCL–> Magnesium Chloride+ Hydrogen or
zinc + sulphuric acid → zinc sulphate + hydrogen or
magnesium + hydrochloric acid → magnesium chloride + hydrogen

Question 16

What is produced most of the times when a metal reacts with an acid?

Answer 16

Salt

Question 17

How do you test for hydrogen and what sound does it need to make to confirm it?

Answer 17

You need to put a lighted splint and it needs to make a squeaky pop.

Question 18

What does tarnish mean?

Answer 18

To lose or cause to lose shine.

Question 19

What is oxidation?

Answer 19

The addition/gain of oxygen.

Question 20

What is the general word equation for oxidation?

Answer 20

Metal+ Oxygen–> Metal oxide.
e.g.
Iron+ Oxygen–> Iron oxide.

Question 21

What is thermal decomposition?

Answer 21

Breaking something down using heat.

Question 22

If we thermally decompose copper carbonate what do we get in a word equation?

Answer 22

Copper Carbonate–> copper oxide+ carbon dioxide
CuCo3–> CuO+ Co2
