5 F2 (g) + 2 NH3 (g) → N2F4 (g) + 6 HF (g)
2. Determine mole proportions , then solveFrom the above balanced reaction, we can see that :
5 moles of F2 reacts to form : 6 moles of HF ,
so, 7.78moles F2 will give :x moles of HF
Therefore,x mole HF =( 6 moles HF * 7.78 mole F2)/ 5 mole F2
= 6 * 7.78/5
=9.336
≈9.34moles HF
• This means that , if you reacted 7.78 moles of F2 , ,9.34 moles of HF would be produced,.
If 15.2g of aluminum reacts with 39.1g of chlorine, how many g of AlCl3 forms?
Answer:
74.9g of AlCl3 are formed.
Explanation:
1st) It is necessary to write and balance the chemical reaction:
[tex]2Al+3Cl_2\rightarrow2AlCl_3[/tex]From the balanced reaction, we know that 2 moles of Al react with 3 moles of Cl2 to produce 2 moles of AlCl3.
2nd) With the molar mass of Al and Cl2, we can convert the moles to grams:
- Al molar mass: 27g/mol
- Al conversion:
[tex]2moles*\frac{27g}{1mole}=54g[/tex]- Cl2 molar mass: 71g/mol
- Cl2 conversion:
[tex]3moles\frac{71g}{1mole}=213g[/tex]Now we know that from the balanced reaction, 54g of Al react with 213g of Cl2.
3rd) Now we have to find out which compound is the limiting reactant and which compound is the excess reactant:
[tex]\begin{gathered} 54gAl-213gCl_2 \\ 15.2gAl-x=\frac{15.2gAl*213gCl_2}{54gAl} \\ x=59.96gCl_2 \end{gathered}[/tex]Now we know that the 15.2g of Al will need 59.96g of Cl2, but we only have 39.1g of Cl2, so Cl2 is the limiting reactant and Al is the excess reactant.
4th) With the molar mass of AlCl3, we can convert the moles to grams of AlCl3:
- AlCl3 molar mass: 133g/mol
- AlCl3 conversion:
[tex]2moles*\frac{133g}{1mole}=266g[/tex]266g of AlCl3 are formed from the balanced reaction.
5th) Finally, with the limiting reactant and the grams of AlCl3 that must be produced from the balanced reaction, we can calculate the grams of AlCl3 that will be formed from 15.2g of aluminum:
[tex]\begin{gathered} 54gAl-266gAlCl_3 \\ 15.2gAl-x=\frac{15.2gAl*266gAlCl_3}{54gAl} \\ x=74.9gAlCl_3 \end{gathered}[/tex]So, 74.9g of AlCl3 are formed.

In lecture, the professor names a molecule 4-ethylpentane. An alert student pointed out that although the correct structure could be drawn, the name did not follow systematic rules. What is the correct systematic name for the molecule?
Answer
C. 3-methylhexane.
Explanation
In a systematic system of naming organic molecules, te longest chain wof carbon ill be considrered first.
So the longest chain of carbon in the molecule will be 6 (hexane) and not 5 (pentane).
The parent name of the molecule will be hexane.
The only methyl group left is bonded to carbon 3 (numbering in such a way the methyl group s given the least number possible).
Therefore, the correct name of the molecule is 3-methylhexane.
The answer is C. 3-methylhexane.
What is the concentration if I have 450 mL of iron (II) chloride (FeCl2) solution that contains9.6 grams of iron (II) chloride solute?

How many moles of NaOH are in 21.4 mL of 1.29 M NaOH?
Answer:
n = 0.0276 mol
Explanation:
Required: Moles of NaOH
Given:
Volume of NaOH = 21.4 mL
Molarity/concentation = 1.29 M
Solution:
We will use the following equation to solve the problem:
[tex]C\text{ =}\frac{n}{V}[/tex]C is the concentration or molarity in mol/L or M, n is the number of moles in mol and V is the volume in L. Therefore we need to first convert mL to L.
1mL = 0.001 L
therefore 21.4 mL = 0.0214 L
Lets re-arrange the equation:
n = CV
n = 1.29 mol/L x 0.0214 L
n = 0.0276 mol
There are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample.
You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change.
Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the
entire sample, and that the sample is in a sealed box, so that no matter can enter or leave.
Sample of Substance X
oli
Change 1
Change 2
Change 3
Change 1 is:
Impossible
a physical change
Change 2 is:
Impossible
a physical change
Change 3 is
Impossible
a physical change
Explanation
Check
Physical change: a new substance is not produced.
Chemical change: produces a new substance.
The substance x has one white dot, two black dots and one white again.
W - B - B - W.
If we look at the change 1 we can see that we have one green, two black and another green.
Is it possible to have one green atom? What does that mean? It means that we have another atom there. The problem says that the sample is in a sealed box, so that no matter can enter or leave. So in my opinion the first one is impossible.
In the second change I can't decide between physical and chemical. I think it is a chemical change because there is a rearrengement.
In the third change there are 12 molecules, Each molecule has two black atoms and 4 white atoms. In the substance x only had 24 white atoms, but in the change 3 we have 48 white atoms. As we said before the sample is in a sealed box, so that no matter can enter or leave. So it also impossible.

10.1. Which is correct about element A whose electron configuration is 1S2/ 2S2 2P4 ?
Has 4 valence electrons and needs 2 to fulfil the octet rule.
Has 4 valence electrons and needs 4 to fulfil the octet rule.
Has 6 valence electrons and needs 2 to fulfil the octet rule.
Has 6 valence electrons and needs 6 to fulfil the octet rule
Answer for number 4: Share the electrons unequally (I think. I am not 100% about this answer)
Explanation: Covalent bonds in which atoms share electrons unequally are polar. Covalent bonds involve the sharing of electrons between two atoms, but those electrons are not always shared equally. As the electronegativity difference between atoms in a covalent bond increases, electron sharing becomes less even.
A sample of liquid ethanol is added to a sealed glass beaker.A sealed beaker contains liquid ethanol, represented as circles. Most of the circles are in the liquid, but a few are in the space above the liquid.Figure © 2019 StrongMindBeaker: BlueRingMedia/ShutterstockWhat will happen to the ethanol after a minute?
We don't have information about how fast the equilibrium will be reached, however, we can analyze the options to see which ones are wrong.
What in fact happens is that the system's previous conditions doesn't matter much. After it is sealed, there is no way something gets out. At first, the system will not be at an equilibrium, it needs some time for that.
The system will have ethanol gas condensating and liquid ethanol evaporating, but at different rates.
Assuming the rate of evaporation is higher at the beginning, we will get more ethanol gas with time, but this will decrease the rate of evaporation a situation where both rates are equal. After that point, the system will be at equilibrium, meaning the amount of liquid and gas won't change anymore.
Having that in mind, the first alternative have the first part wront because the system nees time to get to equilibrium, but its second part is wrong too, because as we said the system will eventually stop getting more ethanol gas.
The second is wrong because both evaporating and condensation are happening at the same time, not one after the other.
The third is wrong because it wil always have an equilibrium. If all ethanol condensates, the rate of condensation will be zero and any evaporation that happens will make some ethanol gas back.
We can't know for sure that 1 minute will be enough to reach the equilibrium, but assuming it is, the fourth alternative perfectly describes what is happening: ethanol condensates and increase the pressure up to a point where both rates equilizes and the system reach the equilibrium.
So, the correct option is the fourth alternative.
A 10 L cylinder of gas is stored at room temperature (25 Celsius) and a pressure of 1800 psi. if the gas is transferred to a 6.0 L cylinder, at what temperature would it have to be stored in order for the pressure to remain at 1800 psi?
Since we want the pressure to remain constant we have to use Charles Law of gases, that relates the volume and the temperature at a constant pressure:
[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]In this case, we know the values of V1, T1 and V2, which are 10L, 25°C and 6.0L. Using these values we have to find T2:
[tex]\begin{gathered} T2=\frac{V2\cdot T1}{V1} \\ T2=\frac{6.0L\cdot25}{10L} \\ T2=15 \end{gathered}[/tex]The gas has to be stored at 15°C.
A person has a sample of gas with a volume of 9.02L and a temperature of 585.57k. If the volume of the container is reduced to 2.24L, what will the new temperature of the gas be in Kelvin?
Step 1 - Understanding the relation between volume and temperature for a gas sample
There are three main variables that can change the state of a gas sample: temperature, pressure and volume. If the pressure (P) is kept constant, the volume (V) becomes proportional to the temperature (T) in K:
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]Step 2 - Substituting the values in the equation above
We know, from the exercise, that V1 = 9.02 L and T1 = 585.57 K, and V2=2.24 L. Substituting these values in the equation above:
[tex]\begin{gathered} \frac{9.02}{585.57}=\frac{2.24}{T_2} \\ \\ T_2=\frac{2.24\times585.57}{9.02}= \end{gathered}[/tex]neutral atoms contain equal numbers of

Answer:
It has a lower density in its solid state than it does in its liquid state
Explanation:
Here, we want to get the unique property of water that helps sustain marine life
As we know, the marine environment consists of several zones with different states. However, it is necessary that aquatic lives are supported in all zones.
In cases where we have a solid state of water, which is ice, aquatic organisms are expected to thrive. Now, the density of water matters in these states.
The density of water is lower in the solid state than in the liquid state, which is unusual for most other liquids. This unique property ensures the sustenance of aquatic lives

How will you describe the pattern as electrons are distributed
How will you describe the pattern as electrons are distributed?
In a simple way, you can say, electrons are arranged around an atom's nucleus.
When electrons are near the nucleus, have the lowest energy. Electrons further aways will have higher energy.
We can say electrons are in different shells with different energy. Inside those shells, electrons are in subshells too.
Then you have some numbers that describe the completly characteristics of an electron in an atom.
They are called Quantum Numbers. They are four
1) The principal Quantum number (n): describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in.
2) The number of subshells or (l): describes the shape of the orbital. It can also be used to determine the number of angular nodes.
3) The magnetic Quantum number (ml): describes the energy levels in a subshell. (Remember we have shells and inside of them we have subshells)
4) The Spin of the Electron (ms): refers to the spin of the electron which can either be up or down.

I have 5 questions that need help to answer 1) What are covalent bonds and how do they form ? 2) How do you know which elements and how many of each are in a compound ?
3) How can you find how many valence electrons an atom has ?
4) How many valence electrons do atoms need to be happy? Which elements are the exceptions?
A covalent bond is one that is formed by two non-metal elements that, due to their low electronegativity difference, neither has the energy to steal the electrons from the other, so they share electrons with each other.
Covalent bonds form when the electronegativity difference between two elements is less than 1.7. In addition, the number of elements must be such that by sharing their electrons, all elements comply with the octet rule, that is, each element shares and completes 8 valence electrons.
