Chemical equation and balancing chemical equations

In this post, we will discuss chemical reactions, chemical equations & the balancing of chemical equations. Chemical Relation & chemical equation – definition & explanation A chemical reaction expresses a chemical change. For example, one chemical property of hydrogen is that it will react with oxygen to make water. We can write that as follows: […]

Energy in Chemical Reactions | exothermic & endothermic

Often, energy is released or absorbed during a chemical reaction. The energy for the welding torch is released when hydrogen and oxygen combine to form water (see the equation below). This welding torch burns hydrogen and oxygen to produce temperatures above 3,000°C. It can even be used underwater.2H2 + O2 → 2H2O + energy Again, […]
