Sulfuric acid is h2so4 and magnesium is m&g not Zn

H2SO4(aq) ---> MgSO4(aq) + H2(g)

Mg(s) + 2H+(aq) + SO42-(aq) ---> Mg2+(aq) + SO42-(aq) + H2(g)

Cancel ions that appear on both sides

Dilute sulphuric acid and magnesium, would this be:

Zn(s) → Zn²+ (aq) + 2e

2H+ (aq) + 2e → H2 (g)

Zn(s) + 2H+ (aq) → Zn2+(aq) + H2 (g)

Also any help with the half and full equations for Bromine water with potassium iodide and hexane, and bromine water with potassium chloride and hexane would be great

Chemistry is really not my strong point
hate redox its one of the hardest topics in AS. thats why i got B in Unit2 Chemistry. but overall i got an A. My best advice is watch videos on youtube and look at older textbooks.
