combined all types if reactions

decomposition of a metal carbonate (CO₃^-2) turns into

a metal oxide + carbon dioxide (CO2)

decomposition of a metal nitrate (NO₃^-1) turns into

a metal nitrite (NO₂) + oxygen gas (O₂)

decomposition of a metal hydroxide (OH^-1) turns into

metal oxide + water (H₂O)

synthesis of a metal oxide + water (H₂O)

forms a BASE 

• has OH in formula 

• has aq at end

synthesis of non metal oxide + water (H₂O)

forms an ACID

• starts with H

• has aq at the end

combustion

the reaction of a substance with oxygen to produce oxides, heat, light

how to recognize :
- O2 will be one of the reactants.
- heat, light, and an oxide will be the products

complete combustion

fuel + oxygen ——> carbon dioxide + water

incomplete combustion

fuel + oxygen ——> carbon dioxide + water + carbon monoxide + carbon.

in single displacement : metal replaces what three things ?

metal replaces metal

metal replaces hydrogen from an acid

metal replaces hydrogen from water

what needs to happen in order for single displacement to occur?

the element replaced must be less active than the one that is replacing

in single displacement, the element replaces another element from what?

an aqueous solution.

what is double displacement

exchange of cation (positively charged)

AX + BY —→ AY+BX

indications of double displacement

1. a solid forms

2. a gas is produced

3. water is formed

in double displacement, what happens when an acid is produced

it further decomposes into h2o + molecule

creates a gas

water is in between what two elements in the activity series

sodium and magnesium
