What is the stable configuration of the nitride ion (N^-3)

1 answer:

3 0

1s^2 ^2s^2 2p^6

Explanation:
Nitride is just an N3− ion. We know this because the -ide- suffex indicates a mono atomic anion, and we assume that the anion will have enough additional electrons to achieve a noble gas configuration (nitrogen is 3 electrons short of a full octet).

<h3>Explanation:</h3>

Step 1: Define

[RxN - Balanced] 2Al₂O₃ → 4Al + 3O₂

[Given] 20 mol Al₂O₃

Step 2: Identify Conversions

[RxN] 2 mol Al₂O₃ → 4 mol Al

Step 3: Stoich

[DA] Set up: $\displaystyle 20 \ mol \ Al_2O_3(\frac{4 \ mol \ Al}{2 \ mol \ Al_2O_3})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 40 \ mol \ Al$

Step 4:Check

Follow sig fig rules and round. We are given 1 sig fig.

Since our final answer already has 1 sig fig, there is no need to round.
