As the pressure of an enclosed gas decreases to half its original value, what happens to the volume of the gas if the temperature is held constant?

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:

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

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.

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.
