Question

Окислительно-восстановительные реакции с указанием цифорок вверху тип H(+1)N(+5)O3(-2) HNO3 + MgO HNO3 + LIOH

Answer 1

2H(+1)N(+5)O(-2)3 + Mg(+2)O(-2) = Mg(+2)(N(+5)O(-2)3)2 + H(+1)2O(-2)
H(+1)N(+5)O(-2)3 + Li(+1)O(-2)H(+1) = Li(+1)N(+5)O(-2)3 + H(+1)2O(-2)

Answer 2

Oxidation-Reduction Reactions

An oxidation-reduction (redox) reaction involves the transfer of electrons between reactants. Let's analyze the given reaction involving the compounds HNO3, MgO, and LiOH.

Balancing the Redox Reaction:

The given reaction is: HNO3 + MgO + HNO3 + LiOH

First, let's balance the reaction by identifying the oxidation states of the elements involved.

Oxidation States: - Hydrogen (H) typically has an oxidation state of +1, except in metal hydrides where it has an oxidation state of -1. - Nitrogen (N) in HNO3 has an oxidation state of +5. - Oxygen (O) in HNO3 has an oxidation state of -2. - Magnesium (Mg) typically has an oxidation state of +2. - Oxygen (O) in MgO has an oxidation state of -2. - Lithium (Li) typically has an oxidation state of +1. - Oxygen (O) in LiOH has an oxidation state of -2.

Balanced Redox Reaction: The balanced redox reaction involving the given compounds is: 3HNO3 + MgO + 2LiOH → Mg(NO3)2 + 2LiNO3 + H2O

Explanation: - The oxidation state of nitrogen in HNO3 changes from +5 to +4, indicating reduction. - The oxidation state of magnesium in MgO changes from 0 to +2, indicating oxidation. - The oxidation state of lithium in LiOH changes from +1 to 0, indicating reduction.

Overall Reaction: 3HNO3 + MgO + 2LiOH → Mg(NO3)2 + 2LiNO3 + H2O

This balanced redox reaction demonstrates the transfer of electrons between the reactants, resulting in the formation of different products.
