Covalent example ch4 where carbon is covalently bonded with all 4 hydrogens
False. At equilibrium, the rate of forward reaction is equal to the rate of backward reaction. The net concentration of both products and reactants won't change, but the reactions still take place.
Density is not a chemical property. It is a physical property.Electromotive force, Flammability and pH are chemical properties.
The answer would be the third one listed, Refraction
2.26%, 26.8%, 2 2/5, 2.62, 271%
Hope this helps! :D
