The answer is the liquid phase
Answer:
8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ molecules are contained in 1 mole of the compound, 3.26*10²⁵ molecules are contained in how many moles of the compound?
amount of moles= 54.12
Molar mass is the mass of one mole of a substance, which can be an element or a compound. Being the molar mass of the compound Mg(NO₃)₂ 148.3 g/mole, so 54.12 moles of the compound contains 8025.996 grams.
<u><em>8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.</em></u>
The Bohr model used to be used but it signifies that electrons stay stationary. The current model uses electron clouds in order to predict the location of an electron within an atom.
Additionally, we can predict the location of an electron, but we cannot exactly pinpoint it. So, the current atomic model cannot have a clear and exact placement for every electron around the nucleus of an atom. It also cannot have a clear and distinct border surrounding the nucleus of an atom where electrons are located.
Therefore, the current atomic model has a predicted area surrounding the nucleus where the electron could be located.
Answer:
Los alcoholes de cadena larga tienen <u>altos</u> puntos de ebullición. Además, cuando tienen <u>ramificación</u>, el punto de ebullición disminuye
Explanation:
El punto de ebullición de un alcohol se ve afectado, las interacciones dipolo-dipolo, las fuerzas de dispersión de van der Waals y los enlaces de hidrógeno.
Las fuerzas de las interacciones dipolo-dipolo y los enlaces de hidrógeno son más o menos las mismas en la serie de alcohol en serie, sin embargo, a medida que aumenta la longitud del alcohol, las fuerzas de dispersión de van der Waals aumentan debido al aumento de la atracción dipolo-dipolo.
Sin embargo, a medida que el alcohol se vuelve más ramificado, el área de la superficie aumenta, lo que disminuye las fuerzas de van der Waals, de modo que se requiere menos fuerza para separar las moléculas y hervir una muestra del alcohol.
Por tanto, los alcoholes de cadena larga tienen puntos de ebullición <u>elevados</u>. Además, cuando tienen <u>ramificación</u>, el punto de ebullición disminuye.
This type of mixture is a heterogeneous mixture. It is any mixture that is not uniform. Heterogeneous mixtures always have more than one phase.It is made up of substances which stays physically separate with each other. Best example is a mixture of sand and sugar. If you get two samples from different points of the mixture and analyze it, you will see that the concentrations of the components are different and that the two solid phases never combine with each other.
