Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces
Brilliant_brown [7]

Answer:

0.364

Explanation:

Let's do an equilibrium chart for the reaction of combustion of ammonia:

2NH₃(g) + (3/2)O₂(g) ⇄ N₂(g) + 3H₂O(g)

4.8atm 1.9atm 0 0 Initial

-2x -(3/2)x +x +3x Reacts (stoichiometry is 2:3/2:1:3)

4.8-2x 1.9-(3/2)x x 3x Equilibrium

At equilibrium the velocity of formation of the products is equal to the velocity of the formation of the reactants, thus the partial pressures remain constant.

If pN₂ = 0.63 atm, x = 0.63 atm, thus, at equilibrium

pNH₃ = 4.8 - 2*0.63 = 3.54 atm

pO₂ = 1.9 -(3/2)*0.63 = 0.955 atm

pH₂O = 3*0.63 = 1.89 atm

The pressure equilibrium constant (Kp) is calculated with the partial pressure of the gases substances:

Kp = [(pN₂)*(pH₂O)³]/[(pNH₃)²*(pO_2)^{3/2}]

Kp = [0.63*(1.89)³]/[(3.54)²*(0.955)^{3/2}]

Kp = 4.2533/11.6953

Kp = 0.364

The chart shows the time, initial velocity, and final velocity of three riders. A 4-column table with 3 rows. The first row labe
gogolik [260]

Answer:

The option which best describes the riders is :

Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating

Explanation:

Franklin is not accelerating as the final velocity (50 km/h) is equal to the initial velocity (50 km/h) , rather he is moving at a constant speed.

Acceleration = (final velocity - initial velocity) / (final time - initial time)

According to acceleration formula given above , the rate at which Gabriella is slowing down is 2.3 km/h and the rate at which Kendall is speeding up is also 2.3 km/h.

Hence the option stating "Gabriella is is slowing down at the same rate that Kendall is speeding up and Franklin is not accelerating"  is true and it best describes the riders.

What is the reducing agent in the reaction below?
trapecia [35]
Al    is  the  reducing  agent.That    is  answer  B  is  the  above  answer
  Al  acts  as  a  strong  reducing  agent.  It  reduces  crO3  to  form cr  while  Al  is  oxidized  to  Al2O3.    Al is  capable  to  reduce  cr  since  Al  is  higher  in   reactivity  series  than  cr.

Structure of cyclopentane
Lynna [10]
This is cyclopentane looks like. Each corner represents carbon atom. Since there are five corners, hence it is called cyclopentane. All the carbons are sp3 hybridized. Hope this helps.
