Solid barium sulfate dissolves into its respective ions at 25°c. suppose that in a particular solution, [ba2+ ] = 1.76 x 10-3 m. find the value of ksp.

Si una estrella no tiene paralaje medible, ¿qué puedes inferir?

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →
