in a reaction CO2 is given off state two different things that you could measure as the reaction was happening to help work out how quickly the reaction was going
mass lost
volume of gases produced
what can make a reaction quicker
powered reactant
high concen.
high temp.
what can make a reaction lower
low temp.
low concen.
lump of reactants
what is mass for the sub-atomic partical
p= 1
n=1
e=0
what is the charge foe neutron
0
what is ionic bonding
non-metal, metal
what is covalent bonding
non-metal
why dose atomic no. have the same no. of p and e
because the atoms need to be neutral
what does exothermic
when the heat exits and become warmer
what does endothermic
when heat heat enters and becomes colder
acid + alkali =
salt + water
acid + metal oxide
salt + water
acid + metal carbonate
salt + CO2 + water
hydrochloric acid makes what salt
