Reaction Types

Question 1

Combination Reaction

Answer 1

A + X → AX

reactant: elements and/or compounds
product: single compound

Question 2

Decomposition Reaction

Answer 2

AX → A + X

reactant: a compound
products: elements and/or compounds

Question 3

Oxidation Reaction

(single replacement)

Answer 3

A + BX → AX + B

reactants: an element (A) and an ionic compound or an acid (BX)
products: an ionic compound (AX) and an element (B)

Question 4

Double Replacement Reaction

(precipitation)

Answer 4

AX + BY → AY + BX

reactants: solutions of ionic compounds or acids
products: a solid ionic compound (precipitate) and an ionic compound or acid

Question 5

Double Replacement

(neutralization)

Answer 5

Question 6

Combustion Reaction

Answer 6

C_xH_yO_z + O₂ → CO₂ + H₂O

1. balance C with CO₂
2. balance H with H₂O
3. balance O with O₂ ( multiply all coefficients by 2 if necessary)
