What is the difference between the molecules of soaps and detergents, chemically ? Explain the cleansing action of soaps. or How many groups and periods are there in the modern periodic table ? How do the atomic size and metallic character of elements vary as we move : 1. along the group...
Explain chemically what happens when soap is added to hard water. Describe the mechanism of the polymerization of styrene. What is it called when an acid is reacted with an alcohol? What is crack nucleation? Is a substance fizzing a composition change? Explain. ...
potash (KOH) leached from the ashes and the animal fat reacted chemically to produce the marvel that we call soap. In addition, purveyors of legend claim that the legendary mountain is the source of the name for soap. It's a good story, however no such mountain exists in Rome or ...
It is also known as lye, although lye may refer to either potassium hydroxide or sodium hydroxide. Pure caustic soda is sold for making candles or soap. Impure caustic soda is found in drain cleaner. Because lye is used to make illegal drugs, it's harder to buy large quantities than in ...
One way of helping students to acquire a balanced view of chemistry is by presenting some “applied” chemistry to them before any “pure” chemistry. This can be done by describing how materials like brick, lime, glass, steel, and soap are made without going into “pure” chemical details...
The capacity of a natural environment to chemically break down an object is referred to asbiodegradability. Some materials break down into organic parts far faster than others, leading them to be referred to asbiodegradable. Measuring the biodegradability of an object can determine how long it will...
As it is forced through spinnerets, cellulose is turned into long, thin fibers. The resulting fibers are immersed in a vat of diluted amine oxide to set, and they are then washed with demineralized water. The lyocell fibers are then dried, and a lubricant, such as silicone or soap, is...
The first such new substances are probably soap and charcoal. When wood is heated it loses water and produces charcoal. In this process, the cellulose of wood - a chemical compound containing the carbon,hydrogen, and oxygen all linked by chemical bonds - undergoes a chemical reaction that ...
Washing soda is sodium carbonate (Na2CO3), and is chemically different from baking soda, which is the common name for sodium bicarbonate (NaHCO3). Sometimes called "soda ash," this moderately basic compound — it has a pH of 11, which is about the same as ammonia — was first made by...
Compounds are sometimes distinguished by whether they're made up of molecules. A molecule is a structure that consists of two or more atoms that are chemically bonded together. The structure might be an elemental or compound molecule. An elemental molecule contains only one type of atom, such ...
