How is electrolysis most commonly used to produce an energy source? splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.

Splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells

 Splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells.

Explanation:  Electrolysis is a phenomenon in which the electrical energy is converted into the chemical energy. In the apparatus of the electrochemical cell, two electrodes are kept in the solution out of which one is positive electrode known as Anode and the other one is Cathode which is the negative electrode.

Thus in electrolysis , water molecules gets split and produces hydrogen gas which can be used in the power machines through hydrogen fuel cells.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
