Sand filters used in drinking water treatment can accumulate manganese oxides (MnO2) as a result of biological oxidation of dissolved Mn(II) in the water. MnO2 has a very low solubility. The Mn(II)-oxidizing bateria use oxygon to oxidize Mn(II). (a) Write the two half reactions and the whole redox reaction for the oxidation of Mn(II) by dissolved oxygen at pH 7. (9 points) (b) Identify the oxidant and reductant for this redox reaction. (6 points) (c) Estimate the energy for this redox reaction. Is it favorable or unfavorable

You are making a solution of calcium chloride dissolved in water. you add solid, stir, and it dissolves. you add just a spatula tip full, stir, and the solid does not dissolve. how could you describe the solutions before and after adding the spatula tip amount
