The reactions of matter whether occurring in natural processes or in the laboratories can be interpreted using another language of chemistry – the equation. A chemical reaction transforms one or more substances into a set of different substances. The substances that enter into a chemical reaction are called reactants and the substances formed are the products.
Cinnabar is a beautiful but toxic red mineral made of mercury (ll) sulfide. It’s used as a source of mercury and to make an artist's pigment called vermilion.
Gas is one of the three forms of matter. Every known substance is either a solid, liquid or a gas. These forms differ in the way they fill space and change shape. A gas, such as air has neither a fixed shape nor a fixed volume and has weight.
A hydrate is a compound that absorbs water molecules and incorporates them into its structure. Inorganic, organic, and gas hydrates exist. The latter may become an important energy source.
It is truly amazing to think about how water has so many unique and amazing properties. But just what is it about water that makes it so versatile, useful, essential, and unique?
Formic acid is found in the sprayed venom of some ants and the secretions of some stinging nettles. The acid is dangerous at high concentrations but has important uses.
Fun dry ice experiments. Make foggy bubbles, screaming metal, frost things over, pop the caps off containers, blow up a balloon, and more.
Chloroform can act an anesthetic, but it’s toxic and causes serious health problems. There are ways to limit our exposure to the chloroform in the environment.
Chemistry can be a very difficult subject to grasp, but is essential for understanding how the world around us truly works. To truly understand Chemistry, one must start with the basics.
Teach kids about mass, volume and density by doing this simple experiment with sugar and water. It's the easiest way to make rainbow water.
Bleach has potent antimicrobial properties and is also able to remove stains from fabrics. It has many uses, but it's potentially dangerous.
REMPI-TOF stands for Resonance Enhanced Multi-Photon Ionization - Time-of-Flight. It is a highly sensitive spectroscopy method for investigation of electron excitation.
A completed lab report that explains the process of determining different aldehydes and ketones, thus classifying them in their respective groups. Includes Method, Abstract, Results, Intro etc.
If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law of periodicity.— Dmitry Ivanovich Mendeleev
