Answer:

Explanation:

Al2(SO4)3 + 3BaCl2 ====> 2AlCl3 + 3BaSO4

Sorry forgot to say that it is a double replacement. The Ba goes where there Aluminum is and the Aluminum goes where the Barium is.

The internal balance numbers come from the fact that the ions and complex ions have different valance numbers.

Answer:

The overall molecular shape (the molecule geometry) changes because of the lone pairs repulsion, but the electron geometry does not change because whether an atom or a lone pair is added there's still two electrons being added.

Answer:

Un par solitario o par de electrones no compartidos es un par de electrones de valencia que no se encuentra formando un enlace, ni compartido con otros átomos. Cuando un átomo se agrupa con otros para formar una molécula, sus electrones más externos -también conocidos como electrones de capa de valencia- dejan de pertenecer únicamente al átomo del que provienen, pasando a pertenecer a la molécula formada. Los orbitales atómicos de valencia dejan de existir como tales y pasan a formar orbitales moleculares con características diferentes a las originales. Como los pares solitarios se encuentran en la capa más externa de los átomos, cuando estos átomos forman moléculas pasan a formar parte del conjunto de electrones de valencia de la molécula. De esto se deduce que los pares solitarios son, de hecho, un subconjunto de los electrones de valencia de la molécula a la que pertenecen.

The products of the reaction would be NaOH and HF

From the question,

We are to determine the products of the reaction between NaF and water in the same manner as the given reaction.

To determine the other product, we will write the equation for the reaction

The equation for the reaction is

NaF + H₂O → NaOH + HF

Hence, the products of the reaction would be NaOH and HF.

Answer:   Germanium has a cubic closest packed structure as a solid. Assuming that germanium has an atomic radius of 159 pm, calculate the density of solid germanium. __________ g/cm3 b.) Germanium has a face-centered cubic unit cell. The density of germanium is 5.32 g/cm3. Calculate a value for the atomic radius of germanium. ___________pm c.) You are given a small bar of an unknown metal X. You find the density of the metal to be 12.0 g/cm3. An X-ray diffraction experiment measures the edge of the face-centered cubic unit cell as 3.89 â„« (1 â„« = 1 ✕ 10−10 m). Identify X.

Explanation:

The density of Germanium is equal to 5.30g/cm^3

Data Given;

For a cubic closest packed = 4r

[tex]4r = \sqrt{2a} \\ a = \frac{4}{\sqrt{2} }r\\ a = \frac{4}{2}*159*10^-^1^0\\ a = 4.50*10^-^8cm[/tex]

The density of the cube is given as the ratio between the mass and volume. But in this case, we have a formula

[tex]d = \frac{Zm}{Na^3}\\ d = \frac{4*72.64}{6.023*10^2^3*9.09*10^-^2^3}\\ d = 5.30 g/cm^3[/tex]

NB;

The density of the cube is equal to 5.30g/cm^3

Answer:

hyrogen,Lithium,beryllium

Answer:

: fluorine, oxygen, or nitrogen.

Explanation:

Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen.

Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen. These three elements are so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient. The H atom nearly acts as a bare proton, leaving it very attracted to lone pair electrons on a nearby atom.

Answer:

4.0 moles of krypton converts to 89.6L.

Explanation:

To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.

We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.

Answer:

1597,5 gm AlCl3 decomposed

Explanation:

2AlCl3 --> 2Al + 3Al2 If you produce 15 moles of Al, how many grams of AlCl3 decomposed? ​

FIRST, you need to write down the the correct reaction.  Your equation makes no sense

here is the correct question

2AlCl3 --> 2Al + 3Cl2    If you produce 15 moles of Al, how many grams of AlCl3 decomposed?

for every mole of Al produced, we decomposed a mole of ​AlCl3

so we produced 15 moles of Al, so we decomposed 15 moles of AlCl3

15 moles are 15 X 106.5 = 1597,5 gm AlCl3 decomposed

Explanation:

The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.

Given what we know, we can confirm that relative atomic mass is calculated by comparing the particles to the atomic mass of a carbon-12 atom.

Therefore, given its abundant nature and the fact that it has been extensively studied, we can confirm that a carbon 12 atom has exactly 6 protons and 6 neutrons, making it very stable and the standard to which other atoms are compared.
