Answer:
3.15 × 10⁻⁶ mol H₂/L.s
1.05 × 10⁻⁶ mol N₂/L.s
Explanation:
Step 1: Write the balanced equation
2 NH₃ ⇒ 3 H₂ + N₂
Step 2: Calculate the rate of production of H₂
The molar ratio of NH₃ to H₂ is 2:3. Given the rate of decomposition of NH₃ is 2.10 × 10⁻⁶ mol/L.s, the rate of production of H₂ is:
2.10 × 10⁻⁶ mol NH₃/L.s × 3 mol H₂/2 mol NH₃ = 3.15 × 10⁻⁶ mol H₂/L.s
Step 3: Calculate the rate of production of N₂
The molar ratio of NH₃ to N₂ is 2:1. Given the rate of decomposition of NH₃ is 2.10 × 10⁻⁶ mol/L.s, the rate of production of N₂ is:
2.10 × 10⁻⁶ mol NH₃/L.s × 1 mol N₂/2 mol NH₃ = 1.05 × 10⁻⁶ mol N₂/L.s
Step 1: When we Write the balanced equation
Then 2 NH₃ ⇒ 3 H₂ + N₂Step 2: Calculate the rate of production of H₂
After that, The molar ratio of NH₃ to H₂ is 2:3. Given the rate of decomposition of NH₃ is 2.10 × 10⁻⁶ mol/L.s, the rate of production of H₂ is:Now 2.10 × 10⁻⁶ mol NH₃/L.s × 3 mol H₂/2 mol NH₃ = 3.15 × 10⁻⁶ mol H₂/L.sStep 3: Calculate the rate of production of N₂
After that, The molar ratio of NH₃ to N₂ is 2:1. Given the rate of decomposition of NH₃ is 2.10 × 10⁻⁶ mol/L.s, the rate of production of N₂ is:Now 2.10 × 10⁻⁶ mol NH₃/L.s × 1 mol N₂/2 mol NH₃ = 1.05 × 10⁻⁶ mol N₂/L.sLearn more about:

Draw a resonance structure, complete with all formal charges and lone (unshared) electron pairs, that shows the resonance interaction of the acetoxy with the ortho position in phenyl acetate.
Answer:
See explanation
Explanation:
The acetoxy group in ortho position in phenyl acetate does interact with the phenyl moiety in the molecule via resonance.
This detailed interaction of the acetoxy group in ortho position in phenyl acetate with the phenyl moiety in the molecule via resonance is shown in the image attached.
This interaction is made possible because the oxygen atom of the acetoxy group has lone pairs of electrons that are suitably positioned to interact with the ring via resonance.

9.16 liters of CO2 weighs how many grams?
Your answer
Answer:
18.0g of CO₂ are present in 9.16L
Explanation:
To solve this question we must use:
PV = nRT
In order to find the moles of the gas and with its molar mass (44.01g/mol for CO₂) we can find the mass of the gas
Assuming STP conditions:
P = 1atm at STP
V = 9.16L
n are the moles of CO₂
R = 0.082atmL/molK
T = 273.15K
Replacing:
PV / RT = n
1atm*9.16L / 0.082atmL/molK*273.15K = n
0.409 moles = Moles of CO₂
The mass is:
0.409 moles CO₂ * (44.01g / mol) =

For a science experiment, I placed an egg in water that had three tablespoons of salt for one week. After 4 days, the egg cracked. At the end of the week, I took it out and cracked the egg. The egg yolk was now solid. This is also called salt-cured eggs. However, I'm not sure whether this is a physical or chemical change.
Answer:
I believe it is a physical change
Explanation:
The telltale sign of a chemical change is the formation of a new substance. They also usually involve the production of energy (heat, light, sound etc.)

What is the mass in grams of 8.65 mol C8H18?
Answer in standard notation to zero decimal places.
PLEASE HELP THIS IS DUE AT 11:59 AT MIDNIGHT AND IM FREAKING OUT
Answer:
m = 998 g
Explanation:
Hello there!
In this case, according to the definition of the molar mass as the mass of one mole of the compound, it is possible to state the 1 mole of C8H18 has a mass of 114.26 grams; therefore, the mass in 8.65 moles turn out to be:
[tex]m=8.65mol*\frac{114.26g}{1mol}\\\\m=998g[/tex]
In agreement to the notation requirement.

For the chemical reaction 2KI+Pb(NO3)2⟶PbI2+2KNO3 how many moles of lead(II) iodide (PbI2) are produced from 8.0 mol of potassium iodide (KI)? number of moles: mol
Answer:
the number of moles is 6
Explanation:
The computation of the number of moles is given below:
According to the question
Since 2 mol of KI produces 1 mol of PbI2
based on the above information
The number of moles would be
8 mol will produce 6 mol of PbI2
Therefore the number of moles is 6
Hence, the same is considered and relevant too

If objects with a greater mass have greater gravitational pull, why is our solar
system, Sun, planets and asteroids, NOT pulled into Alpha Centauri A?
Answer:
It's too far away
Explanation:
According to classical mechanics, gravitational pull is inversely proportional to the distance squared; as the distance increases, the gravitational pull decreases at a faster and faster rate. Since Alpha Centauri A is a few lightyears (Tens of trillions of kilometers away), without even needing to calculate the force of gravity, it is very miniscule.
what is the major organic product obtained from the reaction of 1-butanol with aqueous hbr at reflux
Answer:
1-bromobutane
Explanation:
The reaction of butane with aqueous HBr at reflux is an SN2 reaction. The reaction passes through a single transition state in which the bond between carbon and the leaving group as well as the bond between carbon and the incoming nucleophile are being broken and formed simultaneously. It is a synchronous reaction.
The nuclephile attacks from the backside while the leaving group departs. This leads to inversion of configuration of the product.
The dehydration of the alcohol functional group is a widely used reaction in organic chemistry. The mechanism is generally accepted to always operate via an ______ step-wise process. The _____ mechanism process will always produce (after dehydration) a ________________ style alkene as major product. The driving force for the production of this ________________ style alkene product is generally going to be determined by stability of the ________ ____________.
Answer:
EliminationEliminationZaitsevZaitsevCarbocationExplanation:
The mechanism is generally accepted to always operate via an ELIMINATION step-wise process. The ELIMINATION mechanism process will always produce (after dehydration) a ZAITSEV style alkene as major productThe driving force for the production of this ZAITSEV style alkene product is generally going to be determined by stability of the CARBOCATIONElimination mechanism is the removal of two substituents from a molecule in either a one- or two-step mechanism
Carbocation is a molecule containing a positive charged carbon atom and three bonds
The mechanism is generally accepted to always operate via an elimination step-wise process. The elimination mechanism process will always produce (after dehydration) a Zaitsev style alkene as major product. The driving force for the production of this Zaitsev style alkene product is generally going to be determined by stability of the carbocation.
What is dehydration?
Dehydration is a process in which a water molecule releases from the given compound to form an unsaturated compound.
Dehydration process of alcohol is done by the elimination reaction in which water molecule eliminate and due to this dehydration we get an unsaturated product alkene. This dehydration process is go through the formation of carbocation which in turn forms the product. Stability of the product is determined by the Zaitsev rule and according to this rule most substituted product is the major and stable product.
Hence correct options are: Elimination, elimination, Zaitsev, Zaitsev and carbocation.

Weak bases dissociate
completely into (OH)- and

Answer:
False
Explanation:
When weak bases dissociate, an equilibrium is established rather than dissociating 100%. So OH- and metal ions are partially ionized.
