Chemistry Honors- Patterns in Types of Reactions

What do metallic carbonates form when heated?

Metallic oxides and carbon dioxide gas

What do metallic chlorates form when heated?

Metallic chlorides and oxygen gas (O₂)

What is an active metal?

All group I metals, and group II metals from calcium down

What do active metals and water form?

A metal hydroxide and hydrogen gas (H₂)

Metallic oxides (base anhydrides) and water form what?

Hydroxides

Nonmetallic oxides (acid anhydrides) and water form what?

Acids (put all the terms together and then simplify into its formula unit)

How do you tell if a single displacement reaction will occur or not?

Check the activity series to see if a more active element will replace a less active one

Can less active elements replace more active ones?

No

For group 17 metals, which one is the most active, and how do you tell the order of most—least active?

Fluorine is most active, and everything beneath it becomes less active as you go down the periodic table.

What does hydrogen act as in single displacement reactions?

A metal/cation

What “useful products” are needed from a double displacement reaction?

A precipitate, a gas, or a covalent (molecular) compound

What is a neutralization reaction?

A special type of double replacement reaction involving an acid and a base.
