The Difference Between
Does Cats Pride contain sodium benoite or quartz silica?
Asked in Geology
What is the difference between silica and silicates?
Silica is a bit trickier concept. It refers the combination of silicon plus oxygen. The mineral quartz is silica. But so are the minerals tridymite, coesite, cristobalite and stishovite which are mineral forms of silica that are stable at high temperatures and pressures. All these minerals are also silicates. In other words, quartz is a silicate made of pure silica. But feldspars contain sodium, aluminum, potassium and calcium in addition to silicon and oxygen. Thus feldspars are silicates but they aren't pure silica.
Asked in Chemistry, Fossil Fuels, Air Pollution
Is there a fuel that can be combusted that releases no CO2?
Sodium azide is an extremely toxic (up there with cyanide) powder used as the propellant in airbags. It's combusted in the presence of silica. When it burns, it releases sodium and nitrogen; the silica then combines with the sodium to produce sodium silicate, which is harmless. Another inorganic fuel is thermite--iron and aluminum. Here's your problem: almost all fuels are organic--they contain carbon. Any time you burn a carbon-containing product, the major byproduct is CO2.
What minerals are in light globes?
What do sodium iodide and sodium chloride have in common?
Asked in Elements and Compounds
Do inorganic copmounds have sodium?
Inorganic elements may or may not contain sodium. Some of the inorganic compound that has sodium are sodium hydroxide, sodium nitrate an sodium chloride. Many inorganic compounds including acids do not contain sodium in them. Particular organic compounds may also contain sodium, such as sodium salts of organic acids.
