<h2>Answer: polar covalent bonding</h2>
In polar covalent bonding, electrons are shared <u>unequally </u>between atoms, due to the unequal distribution of electrons between atoms of different elements, slightly positive and slightly negative charges appear in different parts of the molecule.
In this context, water molecule is an exellent example of this type of bonding:
Water (
) can stick to itself through hydrogen bonds, because a water molecule consists of 2 hydrogen atoms attached to 1 oxygen atom.
The oxygen atom tends to monopolize more electrons and keeps them away from hydrogen. Then, it can be said that a water molecule will have a negative side (oxygen) and a positive side (hydrogen).
Thanks to this polarity, water molecules can stick together with the formation of hydrogen bonds to attract a partial positive charge of hydrogen and a more electronegative atom, such as oxygen.

Answer:
El peso de la persona B es la mitad del peso de la persona A.
Explanation:
El peso de la persona B puede calcularse con la siguiente ecuación:
(1)
En donde:
: es la masa de la persona B
g: es la gravedad
Dado que la persona B tiene la mitad de la masa de la persona A, tenemos:
(2)
En donde:
: es la masa de la persona A
Al introducir la ecuación (2) en (1) nos queda:
(3)
Sabemos que el peso de la persona A está dado por:
(4)
Entonces, al introducir la ecuación (4) en (3) tenemos:
Por lo tanto, el peso de la persona B es la mitad del peso de la persona A.
