<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2><u>LE CHATELIER PRINCIPLE</u>:</h2>

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.

-------------------------------------------------------------------------------------------------------------

<h2>EFFECTS ON EQUILIBRIUM</h2><h3 /><h3>__________________________________________________</h3><h3>Temperature: </h3>

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

<h2>_____________________________________</h2><h3>Pressure:</h3>

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.

<h2>_____________________________________</h2><h3>Concentration of moles:</h3>

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.

<h2>_____________________________________</h2><h3>Catalyst:</h3>

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.

<h2>_____________________________________</h2><h2>Question:</h2>

By keeping that in mind,

A) Extra $NH_{3}$ 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

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

An FAS calibration curve (absorbance, y-axis vs. FAS in g/mL) gave an equation he regression line of: y-3678(x)+0.056. If an unk

mezya [45]

Answer:

FAS concentration = 1.61*10^-4M

Explanation:

Beer Lambert's law relates the absorbance (A) of a substance to its concentration (c) as:

$A = \epsilon lc----(1)$

where ε = molar absorption coefficient

l = path length

A plot of 'A' vs 'c' gives a straight line with slope = εl

In addition absorbance (A) is related to % Transmittance (%T) as:

A = 2-log%T----(2)

For the FAS solution, the corresponding calibration fit is given as:

y = 3678(x) + 0.056

This implies that the slope = εl = 3678

It is given that %T = 25.6%

$A = 2-log(25.6)=0.592$

Based on equation(1):

$c = \frac{A}{\epsilon l}=\frac{0.592}{3678}=1.61*10^{-4}M$

Describe in your own words, in terms of particle movement and energy, what occurs when a liquid is heated to its boiling point.

Evgen [1.6K]

Particulate movement and energy increases when a liquid is heated to its boiling point. Explanation: When a liquid is heated to its boiling point, the form of the liquid changes. ... The particles with cinematic energy begin to move more randomly. So we can say that the particle movement and the energy grow.

The following charges on individual oil droplets were obtained during an experiment similar to Millikan's. Determine a charge fo

RSB [31]

Answer:

- 1.602 x 10⁻¹⁹coulombs

Explanation:

Charge on individual oil droplet would be multiple of charge on one electron . So we will find out the minimum common factor of given individual charges that is the LCM of all the charges given.

LCM of given charges like 3.204 , 4.806 ,8.01 and 14.42 . We have neglected the power of ten( 10⁻¹⁹) because it is already a common factor to all.

The LCM is 1.602 . So charge on electron is 1.602 x 10⁻¹⁹.

A solution is prepared by dissolving 8.75 grams of sodium chloride in enough volume of water to produce 112.0 grams of the NaCl

ICE Princess25 [194]

Answer : The percent by mass of the solution is 7.81 %

Explanation : Given,

Mass of NaCl = 8.75 g

Mass of solution = 112.0 g

Now we have to determine the percent by mass of the solution.

$\text{Mass percent}=\frac{\text{Mass of NaCl}}{\text{Mass of solution}}\times 100$

Putting values in above equation, we get:

$\text{Mass percent}=\frac{8.75g}{112.0g}\times 100=7.81\%$

Therefore, the percent by mass of the solution is 7.81 %
