Write a half-reaction for the oxidation of the manganese in mnco3(s) to mno2(s) in neutral groundwater where the carbonate-containing species in the product is hco3–(aq). add h2o and h+ to balance the h and o atoms in the equation. do not add electrons; you may leave the half-reaction unbalanced with respect to charge

The tendency of water molecules to stick together is referred to as a) adhesion b) polarity c) cohesion d) transpiration e) evaporation

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
