The density of glass differs with each type & ranges from 2000 to 8000 kg/m3 for comparison, from less dense than aluminum to more dense than iron at standard conditions. Flint glass contains lead, which is a very dense element. So Flint glass can be so much denser than crown glass
The density of glass is rho = 2,500 kg/m³ or rho = 2,5 g/cm3
A fungus is referred as a member of a large group of eukaryotic organisms which includes microorganisms such as yeasts & molds, as well as the more familiar mushrooms. These organisms are categorized as a kingdom, Fungi that are separate from plants, animals and bacteria.
Fungi comprise evolved to use a lot of different items for food. Some are decomposers living on dead organic material best example leaves. Some fungi spread diseases by using living organisms for food. These fungi infect animals, plants & even other fungi. Athlete’s foot & ringworm are 2 fungal diseases in humans. The mycorrhizal fungi live as partners with plants. Fungi provide mineral nutrients to the plant in exchange for carbohydrates or other chemicals fungi cannot manufacture. Fungi do not have chlorophyll & they are apostrophic in nature.
M + e - - - -> M – E.A.
Basically, the energy which results from this process is negative or close to zero. The more negative this energy the more this method is preferential
The electron affinity is determined of the energy change when an electron is added to a neutral atom to form a negative ion. Best example, whenever a neutral chlorine atom in the gaseous form plucks an electron to form a Cl- ion, it releases energy of 349 kJ/mol or 3.6 eV/atom. To have an electron affinity of -349 kJ/mol & this large number indicates that it forms a stable negative ion. Small numbers indicate which is a less stable negative ion is formed. Group VIA & VIIA in the periodic table have the largest electron affinities.

Alimentary canal is also known as digestive tract, pathway by which food enters the body & solid wastes are expelled. The alimentary canal consists of the mouth, pharynx, esophagus, stomach, large intestine, small intestine, & anus. Alimentary canal is a membrane-lined tube through which food passes & from which wastes are eliminated from the body.
The alimentary canal is referred as a hollow tube of varying diameter, consisting of the esophagus, stomach, small intestine, & large intestine. Alimentary canal has the same basic structural organization throughout its length, in which it always consists of the following 4 layers: (1) the submucosa, (2) the mucosa, (3) the muscularis externa & (4) the adventitia or serosa. Although these 4 layers are always present, they can be strikingly different in appearance in different parts of the alimentary canal. The mucosa, in particular, shows great variability

The structure of the benzene molecule ascertained to be a challenge for chemists for more than forty years after the compound's discovery by Faraday. Benzene structure formula suggests the existence of multiple double &/or triple carbon-carbon bonds, hence there are too few hydrogen atoms for 6 single-bonded carbon atoms.
Benzene is used as a solvent in many industrial, commercial, & research operations. Benzene structure has long been of interest as a fuel due to its high octane number. Some manufacturers have used it as a gasoline additive to increase engine efficiency & to improve starting qualities.

Isomers are referred as compounds with the similar molecular formulae but that are structurally different in some way. It is very important to be able to recognize isomers because they can have different physical properties, chemical, & biological properties.
Conformational isomers are referred as stereoisomer which can be converted into 1 another by rotation around a single bond.
Nonmetals have high ionization electronegativities & energies. Nonmetals are generally poor conductors of heat & electricity. Solid nonmetals are basically brittle, with little or no metallic luster. Most nonmetals have the capacity to gain electrons easily. Nonmetals display a wide range of chemical properties & reactivity.
Nonmetals have Poor thermal conductors
Nonmetals have Poor electrical conductors
Nonmetals are good oxidizing agents.
Nonmetals Have higher electronegativities
Non-metals do not conduct heat or electricity very easily. Non-metals are typically brittle & are not easily molded into shapes. The Best Example of non-metal elements are Hydrogen & Carbon.
