Question

CrO3+NH3->Cr2O3+N2+H2O. Овр электронно ионный баланс

Answer 1

2CrO₃ + 2NH₃ ---> Cr₂O₃ + N₂ + 3H₂O

2CrO₃ + 6H⁺ + 6e ---> Cr₂O₃ + 3H₂O

2NH₃ + 6OH⁻ - 6e ---> N₂ + 6H₂O

2CrO₃ + 6H⁺ + 6e + 2NH₃ + 6OH⁻ - 6e---> Cr₂O₃ + 3H₂O + N₂ + 6H₂O

Answer 2

Electron and Ionic Balance for the Reaction: CrO3 + NH3 -> Cr2O3 + N2 + H2O

To balance the electron and ionic equation for the given reaction, we need to consider the oxidation states of the elements involved and balance the charges on both sides of the reaction.

The given reaction is: CrO3 + NH3 -> Cr2O3 + N2 + H2O

First, let's balance the atoms in the chemical equation: - Chromium (Cr): 1 Cr on the left, 2 Cr on the right - Oxygen (O): 3 O on the left, 3 O on the right - Nitrogen (N): 1 N on the left, 2 N on the right - Hydrogen (H): 3 H on the left, 2 H on the right

Now, let's balance the charges and oxidation states to ensure the electron and ionic balance.

The oxidation states of the elements involved are: - Chromium (Cr) in CrO3: +6 - Nitrogen (N) in NH3: -3 - Chromium (Cr) in Cr2O3: +3 - Nitrogen (N) in N2: 0 - Hydrogen (H) in H2O: +1, Oxygen (O) in H2O: -2

To balance the electron and ionic equation, we need to ensure that the total charge and the number of atoms are the same on both sides of the equation.

Based on the given reaction and the oxidation states, the balanced electron and ionic equation for the reaction CrO3 + NH3 -> Cr2O3 + N2 + H2O is as follows: 6 CrO3 + 8 NH3 -> 3 Cr2O3 + 3 N2 + 10 H2O

This balanced equation ensures that the total charge and the number of atoms are the same on both sides of the reaction.

The balanced equation is obtained by considering the oxidation states and ensuring the conservation of charge and atoms on both sides of the chemical equation.
