Problem- In a sample of three helium atoms the kinetic energies of the atoms were 1.3, 2.5 and 3.1 (in units of 1.0e-21 J). Calculate the average kinetic energy of the sample (in same units). Please show work for full points!:)
Please illustrate work if possible thanks
Provide a method for seperating the mixtures of the compounds, dissolved in a solvent diethyl ether. In each case one of the components will be neutral compound. Give your answer in the form of flow chart.
Question- Bioremediation is the process by which bacteria repair their environment in response, for example, to an oil spill. The efficiency of bacteria for "eating" hydrocarbons depends on the amount of oxygen in the system, pH, temperature, and ..
