D. Sodium and Chlorine
Sodium has 1 electron and Chlorine has 7 electrons. For a compound to be stable, they must have 8 electrons. NaCl = 8 electrons
Fun Fact- You eat NaCl everyday. It's table salt which you put in food.
Answer:
The entropy of the products of a reaction is always greater than the entropy of the starting materials
Explanation:
The second Law of Thermodynamics says that entropy always increases
A + B ----> AB
A and B that were completely arranged in their structures had to be completely messy to form compound AB
When an isolated system reaches a maximum entropy configuration, it can no longer undergo changes: it has reached equilibrium.
Answer:
a. 0.0022 M/s
b. 0.0011 M/s
Explanation:
Let's consider the following reaction.
2 NO(g) + O₂(g) → 2 NO₂(g)
The rate of disappearance of NO is 0.0022 mol NO. L⁻¹.s⁻¹
<em>a. At what rate is NO₂ being formed?</em>
The molar ratio of NO to NO₂ is 2:2. The rate of formation of NO₂ is:

<em>b. At what rate is molecular oxygen reacting?</em>
The molar ratio of NO to O₂ is 2:1. The rate of disappearance of O₂ is:

It would be atomic masses of the same atoms, and that atoms will be isotopes.
