In comparison see it is very easy in goolge
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>
<u>Answer:</u> The molality of 
solution is 0.782 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg. The formula used to calculate molality:
.....(1)
Given values:
Moles of = 0.395 mol
Mass of solvent (water) = 0.505 kg
Putting values in equation 1, we get:
Hence, the molality of solution is 0.782 m
Proton—positive; electron<span>—negative; neutron—no charge. The charge on the proton and </span>electron<span> are the same size but opposite. The same number of protons and </span>electrons<span> exactly cancel one another in a neutral atom.</span>
