2NOCl ⇄ 2NO + Cl₂
K = [NO]²[Cl₂]/[NOCl]
K = [0,0012]²[0,0022]/[0,014]²
K = 0,000000003/0,000196
K = 0,000016163
because a postive and negative can be used in. ion
For the first one, compound might mean more than one thing or i team. But mixture is a very specific definition for chemistry. And for the second one, it would be wrong because “pure” means only that substance, where as it would only be “orange juice”, or something else. But pure refers to only a clean not contaminated substance.
Answer:
0.015 M HNO3 = 0.015 M H3O+ pH = -log(0.015) = 1.82 [OH -] = 1.0 x 10 -14/0.015 M = 6.7 x 10 13 Check: HNO3 is a strong acid, so we expect the pH to be low and the [OH ] to be small
