Asolid mixture weighs 0.6813 g. it contains gallium bromide (gabr3) and other inert impurities. when the solid mixture was dissolved in water and treated with excess silver nitrate (agno3), 0.368 g of agbr was precipitate. a balanced chemical equation describing the reaction is provided below. gabr3(aq) + 3 agno3(aq) ⟶ 3 agbr(s) + ga(no3)3(aq) what is the percent of mass of gabr3 in the solid mixture?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
