Question

Написать полные и сокращённые ионные уравнения:FeCl3 + Na(OH) =NO + O2 = NO2NH3 + O2 = NO + H2ONO2 + О2 + H2O = HNO3В уравнениях со знаком равенства проверить коэффициенты.

Answer 1

FeCl3 +3 Na(OH) =Fe(OH)3↓+3 NaCl
Fe₃⁺+3Cl⁻+3Na⁺+3OH⁻=Fe(OH)3↓+3Na⁺+3Cl⁻
Fe³⁺+3OH⁻=Fe(OH)3↓(р.проходить до кінця)
4NH3 +5 O2 = 4 NO + 6 H2O          
4N⁺+12 H⁺ + 10 O°   = 4N⁺+4O²⁻+6H2O
12H⁺+10O°= 6H2O +4O²⁻(реакція проходить до кінця)  

Answer 2

Full Ionic Equation: FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl

Net Ionic Equation: Fe3+ + 3OH- = Fe(OH)3

Full Ionic Equation: 2NO + O2 = 2NO2

Net Ionic Equation: Not applicable, as all species are molecular.

Full Ionic Equation: NH3 + O2 = NO + H2O

Net Ionic Equation: Not applicable, as all species are molecular.

Full Ionic Equation: 2NO2 + O2 + 2H2O = 4HNO3

Net Ionic Equation: Not applicable, as all species are molecular.

In the full ionic equations, all the reactants and products are written as their respective ions. The net ionic equations only include the ions that participate in the reaction.

To check the coefficients in the equations, we need to ensure that the number of atoms of each element is balanced on both sides of the equation. Let's check the coefficients for each equation:

1. FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl: - Iron (Fe): 1 on both sides - Chlorine (Cl): 3 on both sides - Sodium (Na): 3 on both sides - Oxygen (O): 3 on both sides - Hydrogen (H): 3 on both sides The coefficients are already balanced.

2. 2NO + O2 = 2NO2: - Nitrogen (N): 2 on both sides - Oxygen (O): 4 on both sides The coefficients are already balanced.

3. NH3 + O2 = NO + H2O: - Nitrogen (N): 1 on both sides - Hydrogen (H): 3 on both sides - Oxygen (O): 3 on both sides The coefficients are already balanced.

4. 2NO2 + O2 + 2H2O = 4HNO3: - Nitrogen (N): 4 on both sides - Oxygen (O): 10 on both sides - Hydrogen (H): 4 on both sides The coefficients are already balanced.

All the coefficients in the equations are already balanced.
