Question 8 helpppppp
Answer:
Explanation:
This is lechatlier's principle, which basically talks about how adding or taking away things will disrupt equilibrium and the system will act a certain way to restore equilibrium
1. adding NH3 causes the equilibrium to shift left - produce more reactants
2. removing N2 causes the equilibrium to shift left - produce more reactants
3. same as number 2
4. decreasing pressure causes equilbrium to shift to the side with more moles so it shifts left and produces more reactants
5. catalyst doesn't change anything about equlibrium, it only affects the reaction's rate
Le Chatelier's principle is a principle which predicts the effect of change in condition on a the position of a equilibrium.
Change could be in Temperature, Moles(Concentration), Pressure.
-------------------------------------------------------------------------------------------------------------
EFFECTS ON EQUILIBRIUM__________________________________________________Temperature:We could change the temperature by increasing or decreasing it, and there are two types of reactions, endothermic or exothermic, both have different outcomes by changing the condition.
__________________________________________________________
In Endothermic,
When we increase the temperature, It will favor the formation of product thus MORE PRODUCT will be formed - equilibrium will shift towards right i.e. product side.
When we decrease the temperature, It will favor the formation of reactants thus MORE reactant will be formed - equilibrium will shift towards left i.e. reactants side.
__________________________________________________________
In Exothermic,
When we increase the temperature, It will favor the formation of reactants thus MORE REACTANT will be formed - equilibrium will shift towards left i.e. reactants side.
When we decrease the temperature, It will favor the formation of product thus MORE PRODUCT will be formed - equilibrium will shift towards the right i.e. product side
_____________________________________Pressure:When we increase the pressure, The equilibrium shifts towards the fewer moles of a gas. Wherever there are less moles, it could be any, reactant or product, the increase of Pressure will favor in formation of them.
When we decrease the pressure, The equilibrium shifts towards the more moles of a gas. So whether reactants or product have the higher moles, the decrease in pressure will favor in the formation of them.
_____________________________________Concentration of moles:When we increase the concentration of moles of any substance, The equilibrium will shift away from that substance. So if we want to make more product and there are more moles of reactant present, then Increase the concentration of reactants.
When we decrease the concentration of any substance, The equilibrium will shift towards that substance. So if we want to make more product, decrease its concentration or add more reactant.
_____________________________________Catalyst:By the use of the catalyst, There is no effect on the equilibrium. The rate of both forward and backward reaction are increased with the equal amount.
_____________________________________Question:By keeping that in mind,
A) Extra [tex]NH_{3}[/tex] will shift the equilibrium towards left i.e. more reactants will be formed.
B) Extra N2 is removed, the equilibrium will shift towards the left i.e. more reactants will be formed.
C) N2 is added, the equilibrium will shift towards right i.e. more PRODUCT will be formed. (I assumed there was a typing error and it meant Addition instead of removal)
D) When we decrease the pressure the equilibrium will shift towards the left i.e. more reactant will be formed.
E) Catalyst has no effect on the system

The noble gases include helium, neon, argon, and xenon. What do their electron configurations have in common?
Answer:
their outer electron shell is full
Explanation:
they are named noble because they are non-reactive
The noble gases include helium, neon, argon, and xenon. The electron configurations have in common is that there outer shell i.e. p orbital is full of electrons.
What are electrons?Electrons are defined as a subatomic particle with a negative charge that makes up the nucleus of an atom along with protons and neutrons. Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.
Noble gases are defined as any of a class of extremely stable, very slow-reacting rare gases, such as helium, neon, argon, krypton, xenon, and typically radon. In order of mass, the noble gases are helium, argon, krypton, xenon, and radon. They are known as noble gases because of how beautiful they are and how little they generally react with anything. For this reason, they are also referred to as inert gases. The outer shell of the noble gas are completely filled.
Thus, the noble gases include helium, neon, argon, and xenon. The electron configurations have in common is that there outer shell i.e. p orbital is full of electrons.

Electrical cords are made up of two layers. The wire inside is made of metal. This is surrounded by a cover made of plastic or rubber. How do the wire and cover compare in their ability to conduct or insulate electricity? A. The wire is a conductor, and the cover is an insulator. B. The wire is an insulator, and the cover is a conductor. C. Both the wire and the cover are insulators. D. Both the wire and the cover are conductors.
Answer:
A
Explanation:
The correct answer would be that the wire is a conductor and the cover is an insulator.
The wire inside an electrical cord is made up of metals and metals are generally considered to be good conductors of heat and electricity. The cover which is made of plastic or rubber, however, are known to be poor conductor of electricity. Hence, the wire are considered to be conductors of electricity while the rubber covers act as insulators to protect users from getting electrocuted.

The chemical equilibrium is given:
2NO (g) + O2(g) <—>2N O2, (g)
In a container of volume 10L is in equilibrium a mixture consisting of 10 mol NO (g), 10 mol O2, (g) and 20 mol NO2, (g).
The volume of the container changes under constant temperature and after the restoration of equilibrium the amount of NO has increased by 25%. Calculate the volume change in L.
How do I find the change in volume?
P.s sorry if my English isn’t perfect.
The volume of NO₂=6.25 L
Further explanationAvogadro's stated :
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume = the ratio of gas moles
[tex]\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}[/tex]
the volume of each gas (in a container of volume 10L) :
Total mol=10+10+20=40 mol
NO :[tex]\tt \dfrac{10}{40}\times 10=2.5~L[/tex]
O₂ :[tex]\tt \dfrac{10}{40}\times 10=2.5~L[/tex]
NO₂ :[tex]\tt \dfrac{20}{40}\times 10=5~L[/tex]
NO₂ (has increased by 25%) :
[tex]\tt 0.25\times 5~L=1.25\\\\new~volume=5+1.25=6.25[/tex]
O₂ :[tex]\tt \dfrac{10}{20}\times 6.25=3.125[/tex]

3. A student measured 15.0 grams of ice in a beaker. The beaker was then
placed on a hot plate where it was heated uniformly for a certain amount
of time. During the melting process of the ice, the student noted that the
temperature was at O degree Celsius. When all the ice converted to water,
the final temperature was also at 0 degree Celsius. How much heat was
used to melt the ice?
Please help me !
Answer:
The heat that was used to melt the 15.0 grams of ice at 0°C is 4,950 Joules
Explanation:
The mass of ice in the beaker = 15.0 grams
The initial temperature of the ice = 0°C
The final temperature of the ice = 0°C
The latent heat of fusion of ice = 330 J/g
The heat required to melt a given mass of ice = The mass of the ice to be melted × The latent heat of fusion of ice
Therefore, the heat, Q, required to melt 15.0 g of ice = 15.0 g × 330 J/g = 4,950 J
The heat that was used to melt the 15.0 grams of ice = 4,950 Joules.
If a decrease in temperature accompanies a reaction, what occurred?
Energy was released.
Energy was destroyed.
Energy was created.
Energy was absorbed.
Surely, when there is a decrease in temperature accompanying a chemical reaction, this indicates that: energy was absorbed.
The correct answer choice is option d.
How energy is absorbed by decreasing temperature in a chemical reaction.In happens that in a chemical reaction which leads to the absorption of energy due to decrease in temperature, this results as a result of the fact that bonds in the reactants of the reaction are broken than it is released
So therefore, we can now deduce and confirm from the explanation given above that it is an endothermic reaction when energy is absorbed by the system.

Physical weathering caused by the action of freezing water
Answer:
Frost action involves the ~weathering~ processes caused by repeated cycles of freezing and thawing.
Explanation:
Answer: Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

2.911 grams of ethanol C2H5OH is burned and produces how many grams of water vapor?
Please help me or I'm dead.
Answer:
3.4g
Explanation:
Given parameters:
Mass of ethanol = 2.911g
Unknown:
Mass of water vapor = ?
Solution:
To solve this problem, let us write the balanced reaction equation first;
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
Now find the number of moles of ethanol;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of ethanol = 2(12) + 5(1) + 16 + 1 = 46g/mol
Number of moles = [tex]\frac{2.911}{46}[/tex] = 0.06mole
So;
1 mole of ethanol will produce 3 moles of water vapor
0.06mole of ethanol will produce 0.06 x 3 = 0.19moles of water vapor
Mass of water vapor = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of water vapor = 0.19 x 18 = 3.4g
