Answer:
The periodic table of elements puts all the known elements into groups with similar properties. This makes it an important tool for chemists, nanotechnologists, and other scientists. If you get to understand the periodic table and learn to use it, you'll be able to predict how chemicals will behave.
Answer:
K = [NO₂]⁴[O₂] / [N₂O₅]²
Explanation:
Based on the chemical equilibrium reaction:
2 N₂O₅(g) ⇄ 4NO₂(g) + O₂(g)
The equilibrium reaction is obtained as the ratio between the multiplication of the concentrations of the reactants over the products powered to its reaction coefficient. That is:
<h3>K = [NO₂]⁴[O₂] / [N₂O₅]²</h3>
