equations
acid + metal = salt + hydrogen
acid + insoluble base = salt + water
acid + alkali = salt + water
acid+ carbonate = salt + water + carbon dioxide
metal oxide + carbon = metal = carbon dioxide
structures of carbon
diamond
4 covalent bonds
very strong
doesn't conduct electricity
allotrope of carbon
giant covalent lattice
no delocalised electrons
graphite
3 covalent bonds
many layers
lubricant- layers slide over eachother
conducts electricity and heat
weak intermolecular forces
1 delocalised electron
strong covalent bonds
graphene
one layer of graphite
2D as it is so thin
flexible
can be used in tech
fullerenes
3 covalent bonds
hollow and round
1 delocalised electron
reinforces materials, lubricant, drug delivery
conducts heat and elecricity
allotrope of carbon
exothermic
gives out heat and energy
into surroundings
products have less energy than reactants
makes bonds
endothermic
breaks bonds
products have more energy than reactants
takes in heat- cools down
fromsurroundings
replacement reaction
when a more reactive element takes the place of a less reactive element
eg- magnesium+copper sulfate=magnesium sulfate + copper
base- substance that neutralises an acid to produce a water and salt
strong acids- completely ionise in solution - release
all
ions
weak acids- partially ionise in solution-
don't
release all of their ions
