On the left of the periodic table, the further down you go in a group does it get more or less reactive?
More

Less
Explain how hydrogen is produced during electrolysis of water?
- An electrical current is put through the water
- This splits water into 2H+ and 02- ions
3.The negatives are attracted to the positive anode - At the anode/ cathode either oxidisation or reduction happens
5.Looses electrons = oxidation
Gains electrons = reduction - Eg: 2 oxygen - becomes O2 +2e-
What are the concentration formulas?
mass/ volume
moles/ volume
What’s 1dm cubed in cm cubed?
1000cm cubed
