Inorganic Reaction Types

Question 1

Formation of a binary compound from two elements

Answer 1

2Li(s) + F2(g) → 2LiF(s)

Question 2

Synthesis Things to remember

Answer 2

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.

Question 3

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

Answer 3

2SO2(g) + O2(g) → 2SO3(g)

Question 4

Formation of a new compound from reaction between two compounds

Answer 4

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

Question 5

Binary Decomposing

Answer 5

into elements

Question 6

A metal nitrate decomposing

Answer 6

into a metal nitrite and oxygen gas

Question 7

A metal carbonate decomposing

Answer 7

metal oxide and co2

Question 8

A metal hydroxide decomposing

Answer 8

metal oxide and water

Question 9

Decomposition

Answer 9

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

Question 10

Single Displacement

Answer 10

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

Question 11

a metal (or hydrogen) displaces

Answer 11

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.

Question 12

A non-metal displacing

Answer 12

another non-metal in an ionic solution.

Question 13

A metal displaces

Answer 13

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.

Question 14

Metal + water

Answer 14

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

Question 15

Double Displacement

Answer 15

AB + DC –> AC + DB

Question 16

Precipitation reaction

Answer 16

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

Question 17

gas formation

Answer 17

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

Question 18

Common substances that decompose into water and gas

Answer 18

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

Question 19

Neutralization

Answer 19

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

Question 20

combusion

Answer 20

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

Question 21

complete combustion

Answer 21

produces carbon dioxide and water. hydrocarbon + oxygen combusts

Question 22

incomplete combustion

Answer 22

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