Answer: A solution forms when the attractive _forces_ between the solute and solvent are _similar/higher_ in strength to the solvent-solvent and solute-solute attractions and are therefore able to replace them.
Explanation: Intermolecular forces between solute and solvent must be able to match or exceed the natural intramolecular forces between the solvent-solvent atoms/molecules and solute-solute atoms/molecules.
This is where the solubility law of 'like dissolves like (polar dissolves polar and likewise)' comes into play. Only polar compounds can form such attractive forces with fellow polar compounds and the same story goes for non-polar compounds.
A major factor in how the periodic table<span> is organized is the configuration of each </span>element's<span> valence electrons. Because </span>elements<span> in each family have the same number of valence electrons, they tend to have several similar </span>characteristics<span>.</span>
I think the correct answer is c if not it’s d
Answer:
Although you might think of a machine as complex system of gears, drive belts and and a motor, the definition physicists use is much simpler. A machine is simply a device that does work, and there are only six different types of simple machines. They include the lever, the pulley, the wheel and axle, the screw, the wedge and the inclined plane.
