Which statement best describes a solution? A). a mixture consisting of minute particles suspended in a medium that start moving
about as soon as the mixing process stops. B). a mixture consisting of larger particles suspended in a medium that start settling down as soon as the mixing process stops. C). a mixture having a uniform composition where the components can't be seen separately and all components are in the same state. D). a mixture having a uniform composition but the components can be seen separately and all components are in a different state.
The statement that best describes a solution is the option C: a mixture having a uniform composition where the components cannot be seen separately and all components are in the same state.<span> That is exactly what a solution is: a homogeneous mixture, the composition is uniform, but it can vary from one solution to other. The components must be in the safe phase, but it can be any phase: solid, liquid or gas. The most classical and clear example is the salt solution, NaCl. When you dissolve a spoon of NaCl in water you will not be able to distinguish nor separating the solute from the solvent, and the mixture will have uniform composition.</span>
When move from left to right in periodic table atomic number increases. So element to the right of carbon has one electron more than carbon therefore it's electronic configuration would be 2,5
