Tungsten Metal (W) Element Chemical + Physical Properties
The chemical syol for tungsten is W which stands for Wolfram. The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin “like a wolf”. Pure tungsten metal was first isolated by two Spanish chemists, the de Elhujar brothers in 1783.

Physical and Chemical Properties of Hydrogen Peroxide
Chemical Properties of Hydrogen Peroxide (i) Decomposition: Hydrogen peroxide decomposes to form water and oxygen when exposed to air.This decomposition is exothermic and is acee;erated by heating, addition of alkalis and the introduction of finely divided metals such as platinum, gold and manganese(IV) oxide which acts as a alyst.
A Study Guide: What are the Chemical Properties of Calcium
Every substance has two kinds of properties: physical and chemical. The physical properties of a substance can be examined without changing the substance itself, like its color, density, or magnetic properties. Testing these things doesn’t change the nature of the substance. Testing its chemical properties, however, does change its nature
Physical and Chemical Properties of Solid Waste
Chemical properties of MSW are very important in evaluating the alternative processing and recovery options. Used primarily for coustion and waste to energy (WTE) calculations but can also be used to estimate biological and chemical behaviours. Waste consists of coustible (i.e. paper) and non-coustible materials (i.e. glass).
Physical And Chemical Properties Of Carbon | Chemistry
Allotropes are nothing but forms of an element with varying physical as well as chemical properties. The density of the different forms of carbon depends upon the origin of these elements. You will find some forms of carbon which are pure and some forms which are not pure like coal which is the mixture of both carbon and hydrogen.
