Un sistema material está formado por 10 gramos de sal disuelto en 100 cc de agua,25gr de limadura de cobre, arena y talco en suspensión cuáles son los medios por los cuales se pueden separar todos estos elementos sin perder ninguno y a qué tipo de sistema material considera que corresponde

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

Chemical kinetics what was the rate of reaction in trial 3? choose the closest answer.

Tin has ten stable isotopes. the heaviest, 124sn, makes up 5.80% of naturally occuring tin atoms. how many atoms of 124sn are present in 82.0 g of naturally occurring tin? what is the total mass of the 124sn atoms in this sample?
