Which particle model diagram represents xenon at stp?

1 answer:

3 0

The model that should show the corresct representation of xenon gas is one in which the gas molecules are isolated and monoatomic.

<h3>What is a noble gas?</h3>

A noble gas is a member of group 18 of the periodic table. Noble gases are known not to interact with each other and occur as monoatomic particles.

The images are not shown here hence the question is incomplete. However, we do know that any of the models that show individual monoatomic particles is a representation of xenon gas.

5) Calculate the volume, in liters, of 3.24 x 1022 molecules<br> CI2

azamat

Answer: 1.12 Liters

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{3.24\times 10^{22}}{6.023\times 10^{23}}=0.05moles$

1 mol of $Cl_2$ occupy = 22.4 L

Thus 0.05 mol of $Cl_2$ will occupy = $\frac{22.4}{1}\times 0.05=1.12 L$

One hundred grams of water is saturated with NH CI at

Pepsi [2]

Answer:

About 18 g of NH₄Cl will precipitate.

Explanation:

The <em>table G</em> is the graph of the solubility curves for several solutes which is attached.

The second picture identifies the solubilities for the NH₄Cl at 50ºC and 10ºC.

The solubility of NH₄Cl at 50ºC is about 52 g/ 100 g of water.

The solubility of NH₄Cl at 10ºC is about 34 g / 100 g of water.

Then, at 50ºC 100 g of water saturated with NH₄Cl contains about 52 g of NH₄Cl and 100 g of water saturated with NH₄Cl contains 34 g of NH₄Cl.

The difference, 52g - 34 g of NH₄Cl shall precipitate:

52 g - 34 g = 18g ← answer

The compound Fe2O3 contains how many atoms? <br> A) 2 <br> B) 3 <br> C) 5 <br> D) 7

marishachu [46]

The compound Fe2O3 contains C) 5 total atoms.

This is because there are 2 atoms of Fe (iron) and 3 atoms of O (oxygen) bonded together in this compound, as denoted by the subscripts, and 2+3 = 5.

Hope this helps!
