Please help! :( (will get brainliest)
Here are the 8 models of different molecules: Hydrogen (H2), Oxygen (O2), Nitrogen (N2), Chlorine (CI2), Nitrogen Oxide (NO), Water (H2O), Nitrogen Dioxide (NO2), and Carbon Dioxide (CO2).

When water dissociates, each water molecule splits into a hydroxide ion and a) h 3 o + b) a hydrogen atom c) a hydrogen ion d) h 2 o e) oh —

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

What is the compound name for the formula [ru(en)2cl2]2+ and [co(en)cl2br]-
