For the element that you are doing a lewis dot diagram for you find how many valence electrons it has put the number of valence electrons around the symbol as the dots
3 6
4 1
7 2 <------ that's how you set the number
5 8 Of valence electrons
Answer:
B. Keq = [SO₃][NO]/[SO₂][NO₂].
Explanation:
- For any equilibrium reaction:
Keq = [products]/[reactants].
- For the reaction: SO₂(g) + NO₂(g) → SO₃(g) + NO(g).
<em>∴ Keq = [SO₃][NO]/[SO₂][NO₂].</em>
You can take two liquids of different densities (how much mass is in a given volume) and pour them into a funnel. An example is oil and water. When the mixture settles, the denser liquid will be at the bottom, and drips through the funnel first. This is a separation that you can just let occur naturally.
