Alkali metals are so reactive that they react directly with water in the absence of acid. For Example... 2 K(s) + 2 H2O(l) ¨ 2 K+(aq) + 2 OH− (aq) + H2(g). How many milliliters of hydrogen will be evolved over water when 4.52 g K reacts with an excess of. H2O (l)?

The molar mass is an indirect relection of the polarizablity. Because molecules with higher molar masses often have more protons and thus more electrons the molecule will be more suseptable to polarizablity. Polarizing a molecule is deforming its electron cloud. Some molecules...
Use the equation PV=nRT (pressure times volume equals moles of gas times constant times temperature). Assuming you aren't with-holding information, the number of moles of gas and the temperature must remain the same, so the initial Pressure and Volume must be equal to the ...
