how haloalkane can be prepared by refluxing alcohol with hydrohalic acids
At 20°C the solubility of solid naphthalene in hexane is 0.09 mol/mol of solution. Use this information and the data below to estimate the following for this system: a) The mol fraction of naphthalene in the vapour phase in equ
Carbon compounds containing more than one halogen atom are called polyhalogen compounds. Most of these compounds are valuable in industry and agriculture. Some important polyhalogen compounds are described as follows: Q : Some basic concepts of chemistry an an atom of an element is 10.1 times heavier than the mass of a carbon atom.What is its mass in amu?
