Answer: The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
Hope this helps............ Stay safe and have a Merry Christmas!!!!!!! :D
Adding carbon to iron to make steel does make it stronger and tougher, up to a point. Then it will get stronger but less tough (ie like cast iron). Carbonstrengthens iron by distorting its crystal latice. This distortion is similar in effect to work hardening.
increases iron’s conductivity.
Answer: oxidizes in air
Explanation: Chemical property is the property which deals with change in chemical composition of the substance.
Physical change is the property which deals with change in physical state of the substance.
The above equation represents the oxidation of methane to form carbon dioxide and water. Thus the chemical composition has changed and is a chemical property.
Color and odor only involves no change in chemical composition.
Crystal structure is fluorite
Answer:
Explanation:
Physical hazard means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive.
EXPLODE:
to expand with force and noise because of rapid chemical change or decomposition, as gunpowder or nitroglycerine (opposed to implode).
to burst, fly into pieces, or break up violently with a loud report, as a boiler from excessive pressure of steam.
