What is the Chemical formula for batteries?

Answer 1

Electrolysis of water produces hydrogen and oxygengases at different electrodes.

2H2O(l) --> 2H2(g) + O2(g)

Hydrogen is collected at the cathode.
Oxygen is collected at the anode.

Answer 2

The chemical formula for most alkaline batteries is typically composed of manganese dioxide (MnO2) as the positive electrode, zinc (Zn) as the negative electrode, and potassium hydroxide (KOH) as the electrolyte. Examples of specific battery types may include AA batteries (alkaline) with the chemical formula typically written as Zn/MnO2 or lithium-ion batteries with LiCoO2 as the cathode and graphite (C) as the anode.

Answer 3

If you're electrolyzing water, and if you're doing this in class you almost certainly are, it's

2H2O -> 2H2 + O2

You can electrolyze a lot of things. In industry, they electrolyze salt.

Chloralkali process: produces chlorine, hydrogen gas and sodium hydroxide

2NaCl + 2H2O -> Cl2 + H2 + 2NaOH

Solvay process: produces sodium carbonate and calcium chloride

2NaCl + CaCO3 -> Na2CO3 + CaCl2

Mannheim process: produces hydrochloric acid and sodium sulfate

2NaCl + H2SO4 -> Na2SO4 + 2HCl

Answer 4

Cathode: NH4+(aq) + MnO2(s) + H2O(l) + e- → Mn(OH)3(s) + NH3(aq)

Anode: Zn(s) → Zn2+(aq) + 2e-

NH4Cl(aq) + MnO2(s) + H2O(l) + Zn(s) → Mn(OH)3(s) + NH3(aq) + Zn2Cl(aq)

Answer 5

batteries don't have a chemical formula. there is liquid in the battery that has a formula

Answer 6

electrolysis 2H2O ------------>2H2 + O2
