help plzView attachment 57400
this is a paper 5 question, that means no application booklet, so how am i supposed to write the equation without it
In acidic solutions, balance the equations in order of AOHE (atoms, oxygen, hydrogen and electrons).
- Balance the atoms apart from oxygen and hydrogen.
- Balance the oxygens by adding water molecules.
- Balance the hydrogens by adding hydrogen ions.
- Balance the charges by adding electrons.
MnO4- --> Mn2+ .....................( Step 1 not necessary as Mn is already balanced)
MnO4- --> Mn2+ + 4H2O ................. (balancing the O atoms)
MnO4- + 8H+ --> Mn2+ + 4H2O .........(balancing the H atoms)
MnO4- + 8H+ + 5e- --> Mn2+ + 4H2O........... (balancing the charges)
You can try for the HCOO- to CO2.
