Read the following chemical equation. Cl2 (g) + K+ Br− → K+ Cl− + Br2 (g)

What most likely happens during this reaction?

Potassium loses an electron.
Potassium gains an electron.
Bromine loses an electron.
Bromine gains an electron.

bromine loses an electron

Explanation:

On the right hand side, you can see that  Br became oxidized (  postive because it lost an electron resulting in more protons (+) than electrons (-)). You can see that the charge of K did not change at all. Cl2 become reduced (it gained an electron giving it a more negative charge.)

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

consider the reaction below.
