THE EGG FLOAT TEST!



The Egg Float Test

Together, and with the help of a small bowl of water, let’s save millions of perfectly good eggs from being thrown away. Egg shells are very slightly porous. Over time, air seeps into the shell making it lighter than it was, and, when it is old and no longer good to eat, it floats. Hence, the egg float test.

SUGAR MOLECULES/CHEMICAL FORMULA

Sugar chemical Formula Sugar, also known as saccharose, sucrose or by the chemical name α-D-glucopyranosyl, is a carbohydrate extensively used in the food industry and homemade food preparation. Formula and structure:  The sucrose chemical formula is C 12 H 22 O 11  and the molar mass is 342.30 g mol -1 . The structure is a disaccharide formed by two subunits, one of glucose and one unit of fructose. The crystal structure is monoclinic. Its chemical structure can be written as below, in the common representations used for organic molecules. Physical properties:  Sucrose is white, odorless and sweet taste crystalline solid. It is highly soluble in water (2000 g /L) and other polar solvents. Its density is 1.587 g mL -1 . The sucrose doesn't have melting point, it decomposes up to 186 C. Chemical properties:  The sucrose is formed by two subunits of other very known sugars: fructose and glucose. One of them is a six member heterocycle (glucose ring) ...
