Complete and balance the following half-reaction in acidic solution MnO₄⁻(aq)→MnO₂(s)

The cycle of copper reactions illustrates important principles of chemical reactions. The cycle begins with elemental copper, which in a first reaction is oxidized to copper(II) cation. Copper(II) is then carried through different solid forms. In the last step, copper(II) cation is reduced, the copper metal is regenerated, and the cycle is closed. The five key steps are 1. 3Cu(s) + 2NO, + 8H* → 3Cu²* (aq) + 4H2O+ 2NO 2. Cu (aq) + 20Н (аq) —> Сu(ОН),(s) 3. Cu(OH),(s) –→ CuO(s) + H2O 4. CuO(s) + 2H → Cu²* (aq) + H2O 5. Cu* (aq) + Zn(s) → Zn²*(aq) + Cu(s) 2+ 2+ 2+ cycle reactions. amount of reagents, present answers to the following questions. Assume that you wa carry out a sequence ord use the right Question 1 Question 2 Question 3 How many grams of zinc metal are needed to completely regenerate 1.19 g of copper in the fifth step in the cycle? By how much is zinc oxidized in the fifth reaction?

The reaction between nitric oxide and bromine is described by the following chemical equation: 2NO (g) + Br, (g) → 2NOB1 (g) Suppose a two-step mechanism is proposed for this reaction, beginning with this elementary reaction: NO (g) +Br, (g) → NOB1, (g) Suppose also that the second step of the mechanism should be bimolecular. Suggest a reasonable second step. That is, write the balanced chemical equation of a bimolecular elementary reaction that would complete the proposed mechanism. ローロ
