What is the atomic mass of calcium carbonate? What is the chemical symbol for rhenium? What is the chemical formula for ammonium carbonate? What is the formula for sodium oxide? What is sodium bicarbonate water? What is the chemical symbol for helium?
CaCO3(s)calcium carbonate=CaO(s)calcium oxide+CO2(g)carbon dioxide represents 1 molecule ofcalcium carbonatereacting in the solid state to give 1 molecule of solidcalcium oxideand 1 molecule of gaseous carbon dioxide. As another example, the equation ...
Then calcium oxide mixes with silicon dioxide to create a liquid slag. CaO + SiO2→ CaSiO3 The slag dissolve sat the high temperature of the furnace. In the base of the furnace, the molten slagfloats on top of the denser molten iron and apertures in the corner of the furnace are opened...

When the element is exposed to air, a coating of plutonium oxide forms on the surface that has pyrophoric properties, causing it to glow in the dark [6] Fat man, a massive atomic bomb with a plutonium core, weighing about 6.2 kg, was dropped on Nagasaki during the World War 2 [10]....
For example, it can be produced by passing an electric current through molten (melted) vanadium chloride: It can also be made by combining calcium metal with vanadium oxide: Uses About 90 percent of vanadium goes into steel alloys. Steel containing vanadium is stronger, tougher, and more ...
In 1869, the Russian chemist, Mendeleev, after witnessing a gap between the atomic weights ofcalciumandtitanium, suspected the existence of an undiscovered element. It was only in 1879 when Nilson at the University of Uppsala, Sweden obtained the element from euxenite in the oxide form. He was...
In the 1850s, chemists discovered the effect of tungsten on the properties of steel. However,tungsten steelbegan to be produced and widely used at the end of the 19th century and the beginning of the 20th century.High-speed steel was exhibited for the first time at the Paris World Expositio...
