4 0

The molecule is unstable and impossible to create the PCl_6

Only one way is that change the formula

  • PCl_6-

Lets look at structure(See attachment)

There are total 7atoms

  • P=1
  • Cl=6

N yogurt de 125 g muestra en su etiqueta el contenido de algunas de sus sustancias nutricionales:¿Cuál es la composición en tant
poizon [28]

Answer:

Sustancia  Masa (g)  Composición (% m/m)

<em>Proteínas</em>      5,5                  4,4

<em>Azúcares</em>      5,0                  4,0

<em>Sodio            </em>0,06               0,048

<em>Potasio         </em>0,15                 0,12

                         

Explanation:

Para calcular la composición porcentual en masa de las sustancias debemos usar la siguiente ecuación:

\%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100

En donde:

m_{s} es la masa de la sustancia

m_{sol} es la masa del yogurt = 125 g

Para las proteínas:

\%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 = \frac{5,5 g}{125 g} \times 100 = 4,4 \%

Para los azúcares:

\%_{m/m} = \frac{5,0 g}{125 g} \times 100 = 4,0 \%

Para el sodio:

\%_{m/m} = \frac{0,06 g}{125 g} \times 100 = 0,048 \%

Para el potasio:

\%_{m/m} = \frac{0,15 g}{125 g} \times 100 = 0,12 \%

If you are given the mass number and atomic number of an atom explain how you would find the number of protons neutrons and elec
astra-53 [7]
Atomic number is same number as the protons...

Neutrons =  Mass number - Atomic number ( protons)

Electrons are same number as protons unless the element has a charge..
If it has a charge of +2 it means that the element has 2 less electrons than the neutral atom. If it has a charge of -2 it means that the element has 2 more electrons than what it is supposed to..

At which temperature would the molecules in a one
Nastasia [14]

Answer:

-100 K

Explanation:

<em>Kinetic energy is related to temperature.</em> The molecules in water will move faster in warmer temperatures than in colder ones.

100 K is equal to -279.67°F (-173.15°C). So 100 K would have the lowest average kinetic energy.
