Explique por qué el agua y el cloruro de berilio tienen formula global AX2 y sin embargo el cloruro de berilio es lineal con ángulos de enlace de 180º y el agua es angular con ángulos de 104,5º. Fundamente su respuesta planteando las fórmulas de Lewis de cada sustancia y aplicando sus conocimientos sobre la TRPE y la TEV. ​

Explain why water and beryllium chloride have the global formula AX2 and yet beryllium chloride is linear with bond angles of 180º and water is angular with angles of 104.5º. Support your answer by setting out the Lewis formulas for each substance and applying your knowledge of ERT and VTE.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
