Why asparagus makes your urine smell and onions make you cry. Graduate chemist and secondary school teacher created graphics to brighten up classroom and explain the chemistry of everyday substancesThe anonymous blogger explains why coffee tastes bitter, nutmeg can be a hallucinogen and chocolate isn't an aphrodisiacHe pinpoints the precise chemical compounds responsible from everything from onion breath to colouring and a 'soapy' taste in coriander By Sarah Griffiths Published: 14:44 GMT, 8 April 2014 | Updated: 16:43 GMT, 8 April 2014 Natural food may be healthier than processed, but some can have strange effects on our bodies.
A British graduate chemist and secondary school teacher has created a number of infographics to explain the unexpected chemistry behind some foods - revealing why coffee tastes bitter and chocolate is toxic to dogs. The anonymous blogger started publishing his infographics four months ago after creating some posters to brighten up his classroom and hopes to explain the chemistry of everyday substances. Enlarge. Chemistry - What Is the Importance of Chemistry? Video. Chemistry is the study of matter and its interactions with other matter and energy.
Here's a guide to how chemistry plays into all aspects of life.See Transcript Basics of Chemistry Chemistry is the study of matter and its interactions with other matter and energy. The basics of how things work is the study of chemistry. In a nutshell, the importance of chemistry is that it explains the world around you. Chemistry Relates to Human Life A part of the importance of chemistry lies in developing and testing new medical treatments and medicines. Thanks for watching.

With Anne Marie Helmenstine The transition elements are located in the center of the periodic table and share similar properties.
Learn more about, chemistry, the transition metals and how they relate to each other.See Transcript Transition Metals are Grouped in the Periodic Table of Elements The transition elements are located in groups IB to VIIIB of the periodic table. Because they possess the properties of metals, the transition elements are also known as the transition metals. The Transition Metals Form Ionic Compounds The d electrons are loosely bound, which contributes to the high electrical conductivity and malleability of the transition elements.The transition elements have low ionization energies.

Trends in the Periodic Table Video. Amino Acids - Introduction to Amino Acids Video. Want to learn about amino acids and what composes them?
Here, see lots of facts and helpful information.See Transcript Amino acids are important biochemical molecules. They contain both a carboxyl group (COOH) and an amino group (NH2). This is the general formula for an amino acid where R is the functional group of the amino acid. Facts About Amino Acids Although the neutrally-charged structure is commonly written, it is inaccurate because the acidic COOH and basic NH2 groups react with one another to form an internal salt called a zwitterion.
Nonpolar Side Chains of Amino Acids There are eight amino acids with nonpolar side chains. Polar Side Chains of Amino Acids There are also eight amino acids with polar, uncharged side chains. Charged Side Chains of Amino Acids There are four amino acids with charged side chains. Thanks for watching. About videos are made available on an "as is" basis, subject to the User Agreement. How to Assign Oxidation Numbers Video. Chemisty - Empirical Formula Video. The empirical formula of a compound is its simplest chemical formula, expressed as a ratio of elements in the compound.
Conquer your chemistry fears and learn how to use the empirical formula easily.See Transcript The empirical formula of a compound is its simplest chemical formula, expressed as a ratio of elements in the compound. You can find the empirical formula of a compound using percent composition data. If you know the total molar mass of the compound, the molecular formula usually can be determined as well. To Use the Empirical Formula Easily: • Assume you have 100 g of the substance (this makes the math easier because everything is a straight percent). • Consider the amounts you are given as being in units of grams. • Convert the grams to moles for each element. • Find the smallest whole number ratio of moles for each element.
Empirical Formula Example: As an example, here’s how we can find the empirical formula for a compound consisting of 63% Mn and 37% O. Thanks for watching.
