Lithium + water — lithium hydroxide + hydrogen |
|
|
What is a displacement reaction |
More reactive metals takes the place of a less reactive element , in solutions or in its compounds |
Knocking something over |
|

What’s reduction , reactivity series , ore , native , oxidation |
Reactivity series: a list of elements from most to lest reactive Ore: a rock containing enough metal to make it economic to extract Native metals : un-reactive metals found in their element state . Solid form Reduction is the process of gaining one or more electrons. In an oxidation-reduction, or redox, reaction, one atom or compound will steal electrons from another atom or compound. A classic example of a redox reaction is rusting. When rusting happens, oxygen steals electrons |
Oil rig Oxidation is loss , reduction is gain |

Ph scale |
1-14 1-6 is acids 7 is neutral 8-14 is alkaline |

|
Metals and acids |
Reaction between metals and acids can only occur when the metal is more reactive than the hydrogen in the acid |
|
|
|
Equation for metals and acids reacting : |
Metal + acids — a salt + hydrogen |
|
|
|
Some equations for metals and acids |
Acid + metal— a salt + hydrogen Acid + metal oxide—salt + water Acid + metal carbonate — salt + water + carbon dioxide Acids are defined as proton donors . This means they release h+ ions into solutions Acids are also compounds dissolved in water that produce a solution with a ph lower than 1 |
