Answer:
- <u><em>The reaction moves to the left.</em></u>
Explanation:
If there is only <em>0.500 atm of BrCl(g)</em>, <em>the reaction </em>can only <em>move</em> to the left.
Since there is not any of the substaces that are represented by the left side of the chemical equation, nothing can go to the right.
Since there is BrCl, and it is represented on the right side of the equilibrium equation, it must decompose to produce Br₂(g) and Cl₂(g).
You can represent that situation in a ICE table, which is a table that shows the Initial concentrations (or pressures), the Change, due to the chemical reaction, and the final Equilibrium concentrations (or pressures)
In this case that is:
Br₂(g) + Cl₂(g) ⇌ 2 BrCl(g)
I 0 0 0.500 atm
C +x +x -2x
E x x 0.500atm - 2x
That means that at the equilibrium the pressure of BrCl(g) will be 0.500atm -2x, and the pressures of Br₂(g) and Cl₂(g), each, will be x. Thus, part of the initial BrCl(g) reacts, which means that the reaction moves to the left.
Using that information and the equilibrium constant equation you can calculate the equilibrium pressures of each substance.
Answer:
No, he is not.
Explanation:
When he let the rubber band go, the band compresses, so there's elastic potential energy in it, which will be transformed into kinetic energy when it gains velocity and flies across the room.
Then, Elias had inverted the concepts: the experiment demonstrates the transformation of elastic potential energy to kinetic energy.
Well you use the atomic mass of helium and multiply by the 3.75 grams. Then you will get the answer around 3.7875
The best answer is letter A.
The main factors that change the speed of enzymatic reactions are temperature, pH and substrate concentration (quantity). <span>There are enzymes that need other associated molecules to work. These molecules are called enzyme co-factors. They can be organic ions like mineral salts.</span>
