Quantitative Chemistry- Gases Flashcards
what is the volume of one mole?
The volume of one mole of any gas at room temperature and pressure ( 20 o C and 1
atmosphere pressure) is 24 dm 3
what are oxidation reactions?
When metals react with oxygen to produce metal oxides.
When ______ react they ____ electrons to form ________ ions
When metals react they lose electrons to form positive ions
what is the reactivity series?
The reactivity series places metals in order of reactivity from the most to the least reactive
can you list the reactivity series?
it is; potassium, sodium, lithium, calcium, magnesium, aluminium, (carbon) zinc,
iron, tin, lead, (hydrogen), copper, silver, gold.
A ____ reactive metal can ________ a ____ reactive metal from a ________.
A more reactive metal can displace a less reactive metal from a compound.
Metals ____ reactive than hydrogen will react with ____ and produce h_______ g__.
Hydrogen gas ‘____’ with a _______ splint .
Metals more reactive than hydrogen will react with acid and produce hydrogen gas.
Hydrogen gas ‘pops’ with a lighted splint.
Metals ____ reactive than carbon can be _________ from their ores by _________ with
carbon.
Metals less reactive than carbon can be extracted from their ores by reduction with
carbon.
what does reduction involve?
Reduction involves the loss of oxygen.
what is reduction?
Reduction is the gain of electron.
what is oxidation?
Oxidation is the loss of electrons.
