Mr. Warren's Chemistry Jeopardy

Chemical Balancing

100

Balance the equation:

H₂ + O₂  =>  H₂O

2H₂ + O₂  =>  2H₂O

200

Balance the equation:

P₄ + O₂  =>  P₂O₅

P₄ + 5O₂  =>  2P₂O₅

300

Balance the equation:

Mg + O₂  =>  MgO

2Mg + O₂  =>  2MgO

400

Balance the equation:

CH₄ + O₂  =>  C + H₂O

CH₄ + O₂  =>  C + 2H₂O

500

Balance the equation:

2C₈H₁₈ + 25O₂  =>  16CO₂ + 18H₂O

2C₈H₁₈ + 25O₂  =>  16CO₂ + 18H₂O

Its already balanced :)

Definitions

100

This type of substance is corrosive, tastes sour, and has a pH between 1-6

Acid

200

This type of chemical reaction expels heat into its surroundings

Exothermic

300

This type of reaction requires oxygen and involves an explosion

Combustion

400

This type of substance is typically dull and brittle

Non-Metals

500

This type of reaction happens only to metals

Corrosion

Definitions 2

100

This element is found in 90% of all compounds and is essential to organic chemistry

Carbon

200

These chemicals change colour to show whether a substance is acidic, basic or neutral

Indicators

300

These compounds are new substance formed by a chemical reaction

Products

400

This type of reaction requires heat to proceed

Endothermic

500

This law states that both sides of a chemical reaction must have the same amount of atoms

Conservation of Mass

Word Equations

100

When silver metal is exposed to sulfur, it reacts to form silver sulfide

Silver + sulfur  =>  Silver sulfide

200

Methane gas burns to form carbon dioxide and water.

Methane + oxygen  =>  Carbon dioxide + water

300

Iron becomes iron chloride after reacting with chlorine gas

Iron + chlorine  =>  Iron chloride

400

Potassium hydroxide reacts with sulfuric acid. Potassium sulfate and water are formed in the reaction.

Potassium hydroxide + sulfuric acid  =>  Potassium sulfate + water

500

Sodium corrodes quickly in water, creating sodium hydroxide and releasing hydrogen gas.

Sodium + water  =>  Sodium hydroxide + hydrogen

Mr. Warren

100

Mr. Warren mistakes his water bottle for a bottle of an unknown solution and drinks it. He uses an indicator to test the pH, and it has a pH of 8. Did Mr. Warren drink an acid, base, or something neutral?

A weak base

200

Mr. Warren lights his Bunsen burner and closes the airhole. What colour will the flame be, and what kind of combustion reaction is this?

Yellow/orange. Incomplete combustion.

300

Mr. Warren is shrunk down small enough that he can observe atoms. He examines an atom and sees that it's made of 3 types of subatomic particles. What are the names of these particles?

Proton, neutron and electron
