Oxidation and reduction reactions (redox) involve the loss and gain of electrons. Half-reactions are a way for us to keep track of how many electrons are gained or lost by a particular species during a chemical reaction. These half reactions can be useful in understanding how batteries work, and how other reactions that occur in your body and in nature work as well. Questions 1. In the model, are electrons lost or gained during oxidation

Electrons are lost during oxidation (LEO)

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

lol for the pointsss
