Answer is: distillation.
Solution of sugar and water has a uniform composition and is able to be separated by physical means.
Solution is homogeneous mixture has the same proporties of its components throughout any given sample.
Solution of water and salt, can be separated with distillation (process of heating and cooling). Water evaporates and sugar remain in the beaker.
In order to determine the velocity of gas molecules, it would not be unreasonable to measure the average velocity, vavg, of the gas molecules. However, the molecules of gas are constantly moving in completely random directions and this results in the average velocity being equal to 0 m/s.
Answer:
High melting point is answer
Here N H 4 O H { NH }_{ 4 }OH NH4OH is not a strong electrolyte because it doesn't dissociates completely.
