There are 26 electrons in the nickel ion in the compound NiS.

<h3>How many electrons does the nickel ion contain in the compound NiS?</h3>

The number of electrons in a neutral Nickel atom is obtained from the atomic number of Nickel.

The atomic number of Nickel is 28, therefore, the neutral nickel atom has 28 electrons.

In  the compound NiS, nickel atom loses two electrons to to form the nickel ion.

Number of electrons left = 28 - 2 = 26

Therefore, there are 26 electrons in the nickel ion in the compound NiS.

In conclusion, nickel atom loses two electrons to form nickel ion in NiS.

Darya [45]

Answer:The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas's absolute temperature.

Calcular el valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a
Brums [2.3K]

El valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a una temperatura de 17°C es 47.56 atmósferas.

La presión osmótica se puede calcular usando la siguiente ecuación:

\pi = \frac{nRT}{V}   (1)

En donde:

n: es el número de moles = 2 moles

R: es la constante de los gases = 0.082 L*atm/(K*mol)

T: es la temperatura = 17 °C = 290 K

V: es el volumen = 1 L

Introduciendo lo valores anteriores en la ecuación (1), tenemos:

\pi = \frac{nRT}{V} = \frac{2 moles*0.082 L*atm/(K*mol)*290 K}{1 L} = 47.56 atm

Por lo tanto, la presión osmótica es 47.56 atmósferas.

Pavel [41]

Answer:

Atomic #: 82

Mass #: 206

Charge: 4+

# of protons: 82

# of electrons: 78

# of neutrons: 124

Explanation:

Atomic #: look at the bottom left #, it's always the atomic #.

Mass #: look at the top left # it's always the mass #.

Charge: they give you the charge which is shown on the upper right of the element.

# of protons: is the atomic #

# of electrons: also the atomic # minus 4 bc the charge is a positive 4, indicating that some electrons 'left'.

# of neutrons: 206 (mass # is protons + neutrons) minus 82 (atomic#) which is 124.
