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⁺

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
