Question 8 Helpppppp

Answers

Answer 1

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

Answer 2
Hey There!_____________________________________Answer:LE CHATELIER PRINCIPLE:

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 image above shows a gas held in a chamber with a fixed volume. The gas begins with a temperature 333 K and a pressure of 4.00 atm (green) that increases to 7.65 atm (orange) as the gas is heated. What is the temperature of the gas when the pressure increases to 7.65 atm?

Answers

Answer:

636.86 K

Explanation:

From the question given above, the following data were obtained:

Initial temperature (T1) = 333 K

Initial pressure (P1) = 4 atm

Final pressure (P2) = 7.65 atm

Final temperature (T2) =?

NOTE: The volume is constant.

Since the volume is constant, we can obtain the new temperature the gas by using the following formula as illustrated below:

P1 /T1 = P2 /T2

4/333 = 7.65/T2

Cross multiply

4 × T2 = 333 × 7.65

4 × T2 = 2547.45

Divide both side by 4

T2 = 2547.45 / 4

T2 = 636.86 K

Therefore, the new temperature of the gas is 636.86 K

B. As carbon dioxide concentrations increase, temperatures increase.
C. Carbon dioxide concentrations have no affect on climate.
D. As carbon dioxide concentrations increase, temperatures become more random.

Answers

Answer:

A

Explanation:

When the carbon dioxide concentration goes down, temperature goes down. A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.

Which statement correctly describes a characteristic that a scientific

measuring tool should have?

A. To be precise, it must be able to make measurements repeatedly

over a long period of time.

B. To be precise, it must be able to make measurements with small

units.

C. To be precise, it must be able to make measurements that are

close to the actual value.

D. To be precise, it must be able to make measurements with both

large and small units.

Answers

Answer:

A. To be precise, it must be able to make measurements repeatedly over a long period of time.

Explanation:

The precision of a scientific measuring tool can be defined as how close the values between multiple measurements are to each other, when repeated under the same conditions.

This ultimately implies that, the precision of a scientific measuring tool reflects the reproducibility and repeatability of its measurements, irrespective of how accurate the measurements are.

In science, one of the most effective ways to determine the precision of a scientific measuring tool is to find the difference between the highest and lowest measurements (measured values).

Hence, the statement which correctly describes a characteristic that a scientific measuring tool should have is that, to be precise, it must be able to make measurements repeatedly over a long period of time.

How is a conductor different from an insulator?

A. The free movement of electrons within a conductor permits the transfer of charge.
B. The free movement of protons within a conductor permits the transfer of charge.
C. There is no free movement of electrons within a conductor.
D. There is no free movement of protons within a conductor.

Answers

Answer:

A

Explanation:

Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule. ... The insulator serves as a handle for moving the conductor around on top of a lab table

Answer:

1. Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.

2. Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.

3. Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.

4. Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist:

One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged.

A positively charged cloud comes near a negatively charged cloud.

A cloud with either a positive charge or a negative charge comes near the earth.
