During their middle school years in chemistry class, most children are soaking up knowledge like sponge. Unfortunately, this process is often painful for many of the students involved as they see class as something that is boring and a waste of their time. Luckily you...
Green chemistry: Plastics
By: Sarah Goodbrand
A corn plastic, more scientifically known as Poly lactic Acid (PLA), is biodegradable polyester made mainly from the renewable resource corn starch (Royte, 2006). Corn plastic is an eco friendly plastic which can replace the non-recyclable PET plastic which is made from the non-renewable resource...

For many thousands of years, humans have known and valued the metallic element gold (Au).Too soft for use in making weapons or tools it was for its beauty and rarity that man searched for this metal. Gold’s atomic number of 79 puts the...
The chemical properties of nitrogen
By: Joshua Horn - 257112
Nitrogen is one of the most common elements and it makes up nearly 80% of the Earth's atmosphere. With its unique set of chemical properties, it is a critical component of life as we understand it. Understanding these chemical properties provides some insight into the...
Element facts: Nitrogen
By: Joshua Horn - 257112
Nitrogen, with the chemical symbol N, is a common element that makes up nearly 80% of the Earth's atmosphere. It has an atomic number of 7, with five electrons in its outer shell. This leaves three unpaired electrons for bonding and reactions. Because of this...
An overview about the chemical element Nitrogen
By: Joshua Horn - 257112
Nitrogen is a nonmetal found throughout our world. It is a common and critical component of living organisms. It's unique properties make it necessary for life, but also as a tool and reactant in industry as well. Below is an overview of its properties and...

Organic chemistry is that branch of chemistry which deals with carbon and hydrogen and their mutual bonds. In addition to this basic discipline of chemistry, with the passage of time and with the development of the chemical science there were additional non-conventional areas of chemistry...
How the Bronsted-Lowry theory can predict acid-base reactions
By: Mishra Planeswalker
In 1923, scientists Johannes Bronsted and Thomas Lowry developed a system for better understanding how acids and bases interacted. This was intended as an alternative to the Arrhenius theory and the later-developed Modified Arrhenius theory. In order to understand Bronsted-Lowry’s concept, one must consider...
