Calcula cuantos gramos de KHO se hallan en una disolución total de 650ml siendo que la muestra fue preparada con un 42 % de soluto. Además, calcula cuanto volumen adicional de solvente deberíamos agregar si queremos bajar la concentración del soluto al 30 %.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

when the pressure is increased, there will be a shift to the reactants side. decreasing the volume will increase pressure. when you decrease the volume, the gaseous species get more tightly packed of the concentrations of gaseous species increase.

le chatelier's principle says that the system wants to undo this concentration increase so it can decrease pressure.

since the reactants only have 1 mol of gas (only pcl5) and the products have 2 mol of gas (both pcl3 and cl2), it shifts to reactants to decrease concentration, thereby lowering the pressure
