Will mark 1. the half-reaction 2mno2 + h2o + 2e- mn2o3 is missing a. electrons b. oh- ions c. mn2+ ions d. o2- ions 2. the reaction mg(s) + 2ag+ (aq) → mg2+ (aq) + 2ag(s) will occur because mg(s) is a. a stronger oxidizing agent than ag(s) b. a stronger reducing agent than ag(s) c. reduced d. disproportionated 3. after the equation below has been balanced, what will the coefficients of the reactants and products be, in order? equation: fe²⁺ (aq) + mno₄⁻ (aq) + h⁺ (aq) --> fe³⁺ (aq) + mn²⁺ (aq) + h₂o (l) a. 5, 1, 7, 5, 1, 4 b. 5, 1, 8, 5, 1, 4 c. 1, 1, 2, 1, 1, 4 d. 1, 1, 4, 1, 1, 2

Option B is correct option.

The half-reaction 2MnO2 + H2O + 2e- Mn2O3 is missing  OH- ions.

Explanation:

Full equation:

                                          2MnO2 + H2O + 2e-  → Mn2O3 + 2OH-

The option B which is Mg is stronger reducing agent than Ag is correct option.

Explanation:

Equation:

                               Mg(s) + 2Ag+ (aq) → Mg2+ (aq) + 2Ag(s)

According to equation Mg converts to Mg+2 which means it gives to electron to reduce Ag. So it act as an reducing agent.

The correct option is B. Which is  5, 1, 8, 5, 1, 4.

Explanation:

Full equation :

                  5 Fe²⁺ (aq) + MnO₄⁻ (aq) + 8 H⁺ (aq) --> 5 Fe³⁺ (aq) + Mn²⁺ (aq) + 4 H₂O (l)

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
