Explanation:
Which change in this process would shift the equilibrium to produce the
maximum possible NH3?
3H2 + N2 2 2NH3 + energy
A. Removing the N2 as it forms
B. Removing the NH3 as it forms
c. Decreasing the pressure
D. Increasing the temperature
Answer: B I think, I'll put my reasoning below.
Explanation:
It's not A because removing N2 would only shift the equation the opposite way.
It's not C and D because I don't think those affect the specific amount of each reactant/product produced. I think temperature only affects the speed at which the reaction is performed, which won't affect anything in this case.
Removing the ammonia as it forms is the correct answer to produce the maximum possible NH₃.
What is Haber's Process ?It is an industrial process for manufacturing ammonia by reaction of nitrogen with hydrogen.
N₂+3H₂ ⇌ 2NH₃
The reaction is reversible and exothermic
To answer this question we will consider all the options and answer
Option D ) Increasing Temperature
Haber's process requires an optimal temperature of 450°C ,on Increasing temperature the yield of ammonia gets slow down.
Option C) Decreasing Pressure
Haber's Process requires high pressure to drive the reaction , higher the pressure more is the yield.
Option A ) Removing the N₂ as it forms , on removing N₂ the reaction will drive on the reverse side hence low yield of NH₃ .
Option B) Removing the NH₃ as it forms , this can actually increase the yield as removing the ammonia will lead to shift the equilibrium and therefore increasing the yield.
Therefore Option B , Removing the ammonia (NH₃) as it forms is the correct answer to produce the maximum possible NH₃.

Reset
Next
Answer:
4 m/s
Explanation:
Step 1: Given data
Mass of the balloon (m): 400 kgKinetic energy of the balloon (KE): 3200 JStep 2: Calculate the velocity (v) of the balloon
The kinetic energy is the energy that the balloon has due to its movement. We can calculate the velocity of the balloon using the following expression.
v = √(2 × KE/m)
v = √(2 × 3200 J/400 kg) = 4 m/s

Discuss the nature of the bonding in the nitrate ion ( ) NO32 .Draw the possible Lewis resonance diagrams for this ion.Use the VSEPR theory to determine the steric number, thehybridization of the central N atom, and the geometry ofthe ion. Show how the use of resonance structures can beavoided by introducing a de-localized p MO. What bondorder is predicted by the MO model for the NUO bondsin the nitrate ion
Answer:
Four electrons are bounded by eight electrons
and the bond order = 4/3
Explanation:
The molecular ion has 24 valence electrons and The SN of N in the central of the structure is = 3 according to VSEPR Theory. and this depicts trigonal planar geometry about the central nitrogen also this corresponds to sp^2 hybridization of the valence orbital of the atom N.
The 6 valence electrons are shared between N and O's, while the 2p orbital of Nitrogen will combine with the 2p orbital on each oxygen atoms in order to form four (4) π molecular orbitals. the binding orbital is occupied by a pair of electrons. Four electrons are bounded by eight electrons
and the bond order = 4/3
Attached below is the Lewis structure and resonance structures of the ion ( NO^- 3 )

changes over time?
Answer:
b. the reaction slows down over time as the reactants get used up
Explanation:
just took the test, i hope this helps!!
make sure to take care of yourself :]
The statement " the reaction shows down over time as the reactant get used up." explains how the rate of reaction changes over time.
What is rate of reaction?The rate of reaction is defined as the ratio of the increase in product concentration per unit time to the decrease in reactant concentration per unit time. The rate of reaction varies greatly.
What is rate?The rate of a particular chemical reaction is calculated by dividing the rate of change in a reactant's or product's concentration by the coefficient from the given balanced equation.
What is reaction?Reactions are defined as the change of a chemical substance into an innovative substance through the formation and breaking of bonds among distinct atoms.
It can be seen that with the concentration, the rate of decomposition is also decreased. Generally, it is found that as per hour concentration and rate of decomposition decreases as well.

You have a container which has the capacity to hold 3 L water. If it already has 2.25 L water in it, how much more water in mL can you still add to fill it completely?
Answer:
750mL
Explanation:
According to this question, a container which has the capacity to hold 3 L water already has 2.25 L water in it. This means that the container needs (3 - 2.25) = 0.75L to get filled up completely.
However, this question needs the volume of water needed to fill the container in milliliter (mL). To do this, we say;
1L = 1000mL
0.75L = 0.75 × 1000
= 750mL
Therefore, 750mL of water can still be added to fill up the container completely.

Tungsten and molybdenum both have the BCC crystal structure, and Mo forms a substitutional solid solution for all concentrations at room temperature. Compute the unit cell edge length for a 84 wt% W - 16 wt% Mo alloy. The room-temperature density and atomic weight of W are 19.3 g/cm3 and 183.85 g/mol, the room-temperature density and atomic weight of Mo are 10.22 g/cm3 and 95.94 g/mol, respectively.
Answer:
the unit cell edge length is 3.1585 × 10⁻⁸ cm
Explanation:
Given the data in the question;
density = 100 / [ (84/19.3) + (16/10.22) = 100 / 5.917889 = 16.8979 g/cm³
so Aug density p_aug = 16.8979 g/cm³
Aug Atomic weight = 100 / [ (84/183.85 ) + (16/95.94) = 100 / 0.623665
= 160.3424 g/mol
now
volume = ( no. of atoms in BCC × Aug Atomic weight) / ( Aug density × Avogadro's number)
we substitute
volume = ( 2 × 160.3424 ) / ( 16.8979 × 6.023 × 10²³ )
volume = 320.6848 / 1.017760517 × 10²⁵
volume = 3.15088 × 10⁻²³ cm³
Now, unit cell edge length will be;
= [tex]Volume^{1/3}[/tex]
= [tex](3.15088 * 10^{-23})^{1/3}[/tex]
= 3.1585 × 10⁻⁸ cm
Therefore, the unit cell edge length is 3.1585 × 10⁻⁸ cm

A 17.8 mol H2
B. 17.6 mol HE
C 8.80 mol H2
D3 91 mol H2
Answer:
This is a stoichometric ratio
Explanation:The equation is already balanced, so all you have to do is.
1. Count the molar mass of Ammonia N nitrogen atom has an atomic mass of 14 so add 14+ 3 hydrogens which each have a mass of 1 that gives you 17 grams per mole of ammonia on the right side, so they want to know how much hydrogen is needed to make 100 grams of ammonia, so what you have to do is divide 100/17=2.94 that is your ratio so you now know there is 2.94 times everything in the equation so at first you had 3 moles of hydrogen now you have 3*2.94 moles of hydrogen. You also have 2.94 moles of N2 gas. It's just a ratio if you plug in 200 instead you have to multiply everything by 200/17=11.76 ratio.
1st step count molar mass of product.
2nd plug number they gave you and divide it by molar mass ratio then multiply everything in equation by that ratio.

Choose the options below that are true of a solution of a solid in a liquid. (select all that apply) Select all that apply: Most solids in solution exhibit a general trend of increasing solubility with increasing temperature. A seed crystal may be added to a supersaturated solution to precipitate excess solute. Most solids in solution will dissolve less with increasing temperature. A solution can be saturated at an elevated temperature and subsequently cooled to a lower temperature without precipitating the solute.
Answer:
Most solids in solution exhibit a general trend of increasing solubility with increasing temperature.
A seed crystal may be added to a supersaturated solution to precipitate excess solute.
Explanation:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions(Lumen Learning).
When a seed crystal is added to a supersaturated solution, excess solute begin to precipitate because the seed crystal now furnishes the required nucleation site where the excess dissolved crystals now begin to grow.
