1

Formation of a binary compound from two elements

2Li(s) + F2(g) → 2LiF(s)

2

Synthesis Things to remember

A +B turns to AB. If multivalent, you can't use the periodic table to predict the charges. Non-metals may combine in different ways to produce different compounds. you can't predict this outcome with certainty. Compound can react to create another compound.. Without some information though, this can be hard to predict as well.

3

Formation of a new compound from reaction of an element with a compound.

2SO2(g) + O2(g) → 2SO3(g)

4

Formation of a new compound from reaction between two compounds

Reaction of metal oxide with water to form a metal hydroxide (a base)
Reaction of a non-metal oxide with water to form an acid

5

Binary Decomposing

into elements

6

A metal nitrate decomposing

into a metal nitrite and oxygen gas

7

A metal carbonate decomposing

metal oxide and co2

8

A metal hydroxide decomposing

metal oxide and water

9

Decomposition

AB turns to A + B. There are other types of decomposition reactions which produce more than two products but you can't predict outcome. Ec. Ammonium Dichromate decomposition

10

Single Displacement

A + BC --> AC + B. Higher yp in activity series list, more reactive it is

11

a metal (or hydrogen) displaces

another metal or H+ in an ionic solution. its single valence electron allows it form the cation, H+ ion, and therefore, like metals hydrogen can be involved in single displacement reactions.

12

A non-metal displacing

another non-metal in an ionic solution.

13

A metal displaces

hydrogen from an acid or water. An acid should be thought of in terms of the ions it forms in an aqueous medium. For example, hydrochloric acid should be viewed in terms of aqueous H+ and Cl– ions.Hydrogen can also be displaced from water by a metal, but not as easily as it can from an acid.

14

Metal + water

forms metal hydroxide (Base) and hydrogen gas. This type of reaction can ionize water into H and OH ions

15

Double Displacement

AB + DC --> AC + DB

16

Precipitation reaction

two AQs form one AQ and a solid. You must use solubility table to see which product is precipitate

17

gas formation

one of the products further decomposes into water and a gas.

18

Common substances that decompose into water and gas

H2CO3(aq) → H2O(l) + CO2(g)
H2SO3(aq) → H2O(l) + SO2(g)
NH4OH(aq) → H2O(l) + NH3(g)

19

Neutralization

acid and base react to form water and ionic compound (not acid, not base nor a metal oxide). If acid/base reaction forms an insoluble salt, it is neutralization and precipitation

20

combusion

Combustion is a highly exothermic rapid reaction of a substance with oxygen which results in the production of oxide(s).

21

complete combustion

produces carbon dioxide and water. hydrocarbon + oxygen combusts

22

incomplete combustion

produces carbon monoxide and water. this is due to lack of oxygen ex. yellow flame of candle
