Water and the bad smelling molecule hydrogen sulfide do not seem to have a lot in common at first sight. However, when ...

an 18-carbon saturated fatty acid. The normal numbering system, starting with the carboxylic acid, is shown in blue. The carbons and oxygens of the carboxylic acid functional group are red.

Carboxylic acids can undergo reduction reactions. Reduction is the opposite of oxidation. For example, ethanoic acid (CH 3 COOH) can be formed by the oxidation of ethanol as shown below.

The spectrum of radiation visible to humans maxes out around 740nm, allowing the IR waves to remain undetected by normal observers. The project uses 940nm infrared (IR) LEDs embedded in clothes to ...

Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the α carbon. Each of the 20 amino acids has a specific ...

Despite being thinner and sleeker, the IR remote control that comes with your brand new smart TV isn’t fundamentally different than what we were using in the 1980s. But that doesn’t mean IR ...

Esters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two molecules join and produce a larger ...

Is it an acid, base, or neutral? Make your own acid-base indicator from red cabbage, then test various household substances. Acids and bases are classes of materials that have different properties.

With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are ...
