Answer:
El número de átomos de una molécula depende de la "valencia" de los elementos, ya que es la capacidad de la unión de los átomos.
Explanation:
La valencia de un elemento se define como la medida de la capacidad de combinación de un elemento. Es la capacidad de combinación de un elemento con otros elementos para formar un compuesto químico o molécula.
Básicamente es el número de electrones de valencia que un elemento puede perder, ganar o compartir para formar enlaces químicos requeridos a partir de compuestos o moléculas.
¡¡¡Espero que esto ayude!!!
English Translation
The number of atoms of a molecule depends on the "valency" of the elements since it is the capacity of the union of atoms.
The valency of an element is defined as the measure of the combining ability of an element. It is the combining capacity of an element with other elements to form a chemical compound or molecule.
It is basically the number of valence electrons that an element can lose, gain or share in order to form chemical bonds required to from compounds or molecules.
Hope this Helps!!!
The method which is appropriate for separating a mixture of iron and aluminum is A. using a magnet.
This is because aluminum does not have magnetic properties (thus it will be unaffected by the magnet), so it is easy to sort out all iron from the mixture using a magnet.
What question? Lhh this is hilarious.
Energy released from changing the phase of a substance from the liquid phase to solid phase can be calculated by using the specific latent heat of fusion. The heat of fusion of water at 0 degrees Celsius is 334 J/g. Calculation are as follows:
<span>
Energy = 5 grams x 334 J/g
</span><span>Energy = 1670 J</span>
Answer:
Final Volume = 5.18 Liters
Explanation:
Initial Condition:
P1 = 789 mm Hg x (1/760) atm /mm Hg = 1.038 atm
T1 = 22° C = 273 + 22 = 295 K
V1 = 4.7 L
Final Condition:
P2 = 755 mm Hg x (1/760) atm /mm Hg = 0.99 atm
T2 = 37° C = 273 + 37 = 310 K
V2 = ?
Since, (P1 x V1) / T1 = (P2 x V2) / T2,
Therefore,
⇒ (1.038)(4.7) / 295 = (0.99)(V2) / 310
⇒ V2 = 5.18 L (Final Volume)
