Types of reactions

Decompostion

A → B + C

One reactant

redox: depends

combination

A + B → C

one product, reactants are typically elements.

Redox: Yes

combustion

A + O2 → CO2 + H2O

reactants with C, H, sometimes O

Redox: Yes

Single replacement 

A + Bx → B + Ax

element reacting with a compound or ion 

Redox: Yes 

LOOK AT ACTIVITY SERIES (to determine if a reaction or not)

If element stronger (left side) but alr an ion → N.R. ( must end as an ion)

Double Replacement (displacement)

Ax + By → Ay + Bx

Typically 2 aqueous solutions reacting

Redox: No

Neutralization

Ha + BOH → HOH + BA

acid and base ( metal hydroxide)

Redox: No

HI

Hydroiodic acid

HCI

Hydrochloric acid

HBr

Hydrobromic acid

HNO₃

Nitric acid 

HClO₃

Chloric acid

HClO₄

perchloric acid

H2SO4

Sulfuric acid
