Chapter 3: Stoichiometry

Question 1

Combustion Reaction

Answer 1

a compound reacts with an oxidizing element, such as oxygen or fluorine, and the products are compounds of each element in the fuel with the oxidizing element. For example:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)

Question 2

Decomposition Reaction (Cleavage Reaction)

Answer 2

The separation of a chemical compound into elements or simpler compounds. For example:
NH3(g) → N2(g) + H2(g)

Question 3

Condensation Reaction (Combination)

Answer 3

A chemical reaction in which two molecules or moieties (functional groups) combine to form a larger molecule, together with the loss of a small molecule

Example:
A+B → AB

Question 4

Exchange Reaction (Displacement)

Answer 4

AB+C → AC+B
or
AB+CD → AD+CB

Question 5

Acid-Base (Neutralization)

Answer 5

Involves the transfer of H+ ions

Question 6

Oxidation-reduction (Redox)

Answer 6

Reactions involve changes in oxidation states

Example:
H2 + F2 → 2 HF
