Answer:

[Ne] 3s^{2}

Explanation:

You can alternatively write it as 1s^{2}2s^{2} 2p^{6}3s^{2}, but since noble gasses like neon are stable, we simply write their letter and then the configuration that goes after them.

Buffering capacity refers to: the effectiveness of commercial antacids the extent to which a buffer solution can counteract the
kirill [66]

Answer: Option (b) is the correct answer.

Explanation:

Buffere is defined as the solution to whom when an acid or base is added then it resists any in change in pH of the solution.

This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. So, basically it keeps the concentration of both hydrogen ions and hydroxides equal. As a result, it helps in maintaining the pH of the solution.

And, the capacity of a buffer solution to resist the change is known as buffer capacity.

Thus, we can conclude that buffering capacity refers to the extent to which a buffer solution can counteract the effect of added acid or base.

1. Is this equation balanced? Explain your answer. Na + Cl2 → NaCl ?
Delvig [45]

It is not balanced since there are 2 Cl molecules on the left side, and only 1 on the right side. In order to balance this, you would need to make sure there are the same amount of all the molecules on both sides...

4Na + 2Cl2 = 4NaCl


Hope this helps :)
