The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves.

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

We can measure the rate of the reaction by measuring how fast the ... reacts with dilute hydrochloric acid to produce sodium chloride, water, sulfur dioxide and sulfur. The sulfur makes the ...

A recent study from the Earth-Life Science Institute (ELSI) investigates how polyester microdroplets, potential precursors to modern cells, could form under realistic early Earth conditions.
