Here is a more complex redox reaction involving the permanganate ion in acidic solution: 5fe2+ + 8h+ + mno4− → 5fe3+ +mn2+ + 4h2o classify each reactant as the reducing agent, oxidizing agent, or neither. drag the appropriate items to their respective bins.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
