Evidence for a chemical reaction |
gas released insoluble solid is produced called precipitate color change heat energy change |
|
|
heat released |
exothermic reaction |
|
|
heat absorbed |
endothermic reaction |
|
|
Combination reaction: a. b. c. |
a. Metal and oxygen = metal oxide b. Non metal and oxygen = nonmetal oxide c.metal and non metal = ionic compound |
|
|
decomposition reaction: a. b. |
a. Metal hydrogen carbonate + heat metal carbonate + water + CO2 b. Metal carbonate + heat metal oxide + CO2 |
|
|
Single Replacement |
A + BZ ➡️ AZ + B predictions are made by using an activity series |
|
|
Activity series |
is a sequence of metals arranged according to their ability to undergo a replacement reaction TOP = most active/most reactive BOTTOM = least reactive/least active

|
net ionic equation |
is a chemical equation that shows only those substances which are reacting.

|
Oxidation Reduction Reactions or Redox |
* reactions where a change in electrons occurs * one compound loses and another gains electrons
