Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and

Chemical reactions are the basis of life on earth. As human beings‚ we are little more than the naturally abundant elements of which we are composed and the reactions between the compounds that they form. After all‚ how could life exist without water? Oxygen transport in a body the size of the human body would be impossible without the aid of a complex like hemoglobin. Besides being the basis of many of life’s intangibles‚ chemistry also plays an active role in our daily lives. Take for instance
