In this activity, you will practice balancing overall redox reactions in acidic and basic solutions. To do this, you will apply the half-reaction method for balancing redox equations.
1.) NH4+ + MnO4- → NO3- + Mn2+ (acidic solution)

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

l dont know l am s sorry
