What’s the chemical formula for glass?
All of the most important glasses are based on silica SiO2. Two glasses of special interest are soda-lime glass, used in windows and bottles, with composition 70SiO2. 10CaO. 15Na2O, and borosilicate glass, used in cooking and chemical glassware, with composition 80SiO2.
What is Coals chemical formula?
Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C137H97O9NS for bituminous coal and C240H90O4NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster.

Why HCl is liquid?
As there is hydrogen bonding in case of HF so it is liquid whereas HCl is gas as there is lack of hydrogen bonding in HCl.
What is the molar mass of aspirin c9h8o4?

180⋅g/mol.
Why is glass chemically inert?
Glass bottles do not react with the chemical solutions as glass is mostly composed of silica (SiO2) and silicates (SiO3), which leads to strong covalent bonding between Silicon and Oxygen atoms and is therefore chemically inert to react with chemical solutions.
What are coal hydrocarbons?
Conversion. In general, coal can be considered a hydrogen-deficient hydrocarbon with a hydrogen-to-carbon ratio near 0.8, as compared with a liquid hydrocarbons ratio near 2 (for propane, ethane, butane, and other forms of natural gas) and a gaseous hydrocarbons ratio near 4 (for gasoline).
What is coal chemistry?
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.
What type of mineral is a corundum?
Minerals Database. Corundum. Corundum is a crystalline form of aluminum oxide (Al2O3) with traces of iron, titanium and chromium. It is a rock-forming mineral. It is one of the naturally transparent materials, but can have different colors when impurities are present. Transparent specimens are used as gems such as sapphires and rubies.
What is the color of transparent corundum?
It is one of the naturally transparent materials, but can have different colors when impurities are present. Transparent specimens are used as gems such as sapphires and rubies. Rubies are red due to traces of chromium in the corundum. All other colors of transparent corundum are called sapphires.
