Can one atom in this type of reaction win the "tug of war"? What might happen if it did?
Luden [163]

Answer:

POLAR BONDS will form.

A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.

El lago Don Juan, es considerado el más salino de la Tierra, contiene en sus aguas 3.72 mol/kg de cloruro de calcio (CaCl2) y 0.
Alex73 [517]

Answer:

412.8 \frac{gCaCl_2}{kg\ agua} \\\\29 \frac{gNaCl}{kg\ agua}

Explanation:

¡Hola!

En este caso, dado que se nos dieron las moles de cada sal por cada kilogramo de agua, es necesario para nosotros calcular los gramos por medio de la masa molar de estas, que son 110.98 g/mol y 58.44 g/mol respectivamente.

De este modo, realizamos las conversiones de moles a masa como se muestra a continuacion:

3.72\frac{molCaCl_2}{kg\ agua} *\frac{110.98gCaCl_2}{1molCaCl_2}=412.8 \frac{gCaCl_2}{kg\ agua} \\\\0.5\frac{molNaCl}{kg\ agua} *\frac{58.44gNaCl}{1molNaCl}=29 \frac{gNaCl}{kg\ agua}

¡Saludos!
