2Na + H2O -> 2NaOH+H2
A properly written chemical equation will always show the same number of atoms of each elemental on each side, showing that no atoms are created or destroyed in the chemical reaction.
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
Most chemical equations have a few standard elements (no pun intended). There are the reactants on the left side, the arrow showing the direction of the reaction, and the products on the right side. Sometimes, properties of the reaction such as the enthalpy is shown after the equation. Often times, especially in organic chemistry, there will be other compounds or parameters written above and/or below the reaction arrow to indicate what chemicals were needed to make the reaction occur.

All properly solved chemical equations demonstrate the law of conservation of mass by having the same number of atoms on both sides, showing that no atoms were created or destroyed in the chemical reaction.
The reaction between strontium and nitrogen gas (which has the formula N2) produces strontium nitride, which has the formula Sr3N2. The balanced equation is: 3Sr + N2 -> Sr3N2. If there is an excess of oxygen available, the balanced equation for reaction between indium and oxygen is: 4 In + 3 O2 -> 2 In2O3.

This chemical reaction is:2 Mg + O2 = 2 MgO
It means that a chemical reaction has taken place, and copper sulfate, carbon dioxide, and water have combined somehow. Then there would be an "equal" sign, and on the other side of the chemical equation would be another bunch of symbols for compounds, showing what chemicals came out of the reaction.
