The amount of manganese in steel is determined by changing it to permanganate ion. the steel is first dissolved in nitric acid, producing mn2+ ions. these ions are then oxidized to the deeply colored mno4- ions by periodate ion (io4-) in acid solution. (a) complete and balance an equation describing each of the above reactions. (type your answer using the format co2 for co2, (nh4)2co3 for (nh4)2co3, [nh4]+ for nh4+, and [ni(cn)4]2- for ni(cn)42-. use the lowest possible coefficients.) equation 1

Explanation:

The first reaction is oxidation of Mn to Mn²⁺ with HNO₃:

(4H⁺ + NO₃⁻ + 3e⁻ → NO + 2H₂O) x2

(Mn → Mn²⁺ + 2e⁻) x3

(1) 3Mn + 8H⁺ +  2NO₃⁻ → 3Mn²⁺ + 2NO + 4H₂O

The oxidation to MnO₄⁻ with IO₄⁻ is:

(2e⁻ + 2H⁺ + IO₄⁻ → IO₃⁻ + H₂O) x5

(Mn²⁺ + 4 H₂O → MnO₄⁻ + 8H⁺ + 5e⁻) x2

(2) 2Mn²⁺ + 5IO₄⁻ + 3H₂O → 2MnO₄⁻ + 5IO₃⁻ + 6H⁺

the dependant variable is spilled water

the independent is the heat

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
