Observe: click reset. select the gas collection setup. chemists use this apparatus to collect any gases produced in the reaction

. from the reaction flask, gases travel through a long tube and into a cylinder of water. as gases bubble into the cylinder, the water is displaced (removed) until the cylinder is filled with gas. click play and observe the cylinder. was any gas produced in the reaction? [ ]

Hello. Although it is not possible to see the video to which the question refers, we can see, in the question, that water is removed from the cylinder as a gas is added to the same cylinder. So we can see that a gas was produced in the reaction, through the displacement of water, that is, if the water starts to be removed from the cylinder, it is because the reaction is producing a gas. If the gas is not produced, water will not come out of the cylinder.

What are the equilibrium partial pressures of pcl3 , cl2, and pcl5, respectively? express your answers numerically in atmosphere
aliina [53]
The question is incomplete, so I tried to find a similar problem online. It is shown in the attached picture. The reaction is

PCl₃ + Cl₂ ⇆ PCl₅

Then, we use the ICE (Initial-Change-Excess) approach as follows:

        PCl₃ + Cl₂ ⇆ PCl₅
I        0.5      0.5      0.3
C      -x         -x        +x
E    0.5-x    0.5-x    0.3+x

Total pressure: 0.5 - x + 0.5 - x + 0.3 + x = 1.3 

Kp = [PCl₅]/[PCl₃][Cl₂]
0.18 = (0.3+x)/(0.5-x)²
Solving for x,
x= 0.21

Partial pressures would be:
<em>PCl₃ = 0.5 - 0.21 = 0.29 atm</em>
<em>Cl₂ = 0.5 - 0.21 = 0.29 atm</em>
<em>PCl₅ = 0.3+0.21 = 0.51 atm</em>

In the electron transport system, hydrogen atoms removed from NADH ultimately end up as part of __________. In the electron tran
guajiro [1.7K]
<h3>Answer:</h3>

Water

<h3>Explanation:</h3>
  • The electron transport chain is the third and the last phase of aerobic cellular respiration in living organisms.
  • During the electron transport chain, electron carriers NADH and FADH₂ are used to generate energy in the form of ATP.
  • During this phase, energy is generated through oxidative phosphorylation in the inner membrane of the mitochondrion.
  • In the electron transport chain, hydrogen ions are transferred from NADH and FADH₂ and ultimately end up as part of water.
