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.
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
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)
batteries don't have a chemical formula. there is liquid in the battery that has a formula
electrolysis 2H2O ------------>2H2 + O2
=Effrin=
H2O is 2 hydrogens plus 1 oxygen and that makes the chemical formula for water.
The chemical formula for oxide is O2−
Any chemical formula; beans are not chemical compounds.
The chemical formula of Taconite is Fe3O4.
the chemical formula for a ribose is C12H22O11.
The chemical formula of sulfuric acid is H2SO4.
A battery is a device, an instrument, not a compound with a definite formula; for details see the link below.
Cooling lowers the rate of the chemical reaction in the batteries.
what are the physical properties of batteries
Chemical energy. Batteries also convert chemical energy to electrical energy.
batteries store chemical energy
Energy has no chemical formula as it is not a chemical.
Batteries works based on chemical reactions.
Batteries use chemical energy to create voltage to drive current flow. They do not use nuclear energy.
Chemical energy.
YES.
The example of conversion of chemical energy to electrical energy is the process occurring in the batteries.
