Question

Из предложенного ряда формул выпишите в первую очередь формулы веществ,которые реагируют с гидроксидом натрия,затем формулы веществ ,реагирующих с азотной кислотойMg(OH)2; Al(OH)3; H2SO4; Na2CO3напишите уравнения соответствующих реакций в молекулярном и ионно-молекулярном видезаранее спасибо

Answer 1

Al(OH)3+NaOH=Na[Al(OH)4]
H2SO4 + 2NaOH = Na2SO4 + 2H2O
Mg(OH)2 + 2HNO3 = Mg(NO3)2 + 2 H2O
Al(OH)3 + 3HNO3 = Al(NO3)3 + 3H2O
Na2CO3 + 2HNO3 = 2NaNO3 + CO2 + H2O 
Вроде так..

Answer 2

Formulas of Substances Reacting with Sodium Hydroxide (NaOH):

The substances that react with sodium hydroxide (NaOH) are magnesium hydroxide (Mg(OH)2), aluminum hydroxide (Al(OH)3), sulfuric acid (H2SO4), and sodium carbonate (Na2CO3). Let's write the equations for the corresponding reactions in molecular and ion-molecular forms.

1. Magnesium Hydroxide (Mg(OH)2): - Molecular Equation: Mg(OH)2 + 2NaOH -> Mg(OH)2 + 2NaOH - Ion-Molecular Equation: Mg2+ + 2OH- + 2Na+ + 2OH- -> Mg(OH)2 + 2Na+ + 2OH-

2. Aluminum Hydroxide (Al(OH)3): - Molecular Equation: Al(OH)3 + 3NaOH -> Al(OH)3 + 3NaOH - Ion-Molecular Equation: Al3+ + 3OH- + 3Na+ + 3OH- -> Al(OH)3 + 3Na+ + 3OH-

3. Sulfuric Acid (H2SO4): - Molecular Equation: H2SO4 + 2NaOH -> H2SO4 + 2NaOH - Ion-Molecular Equation: 2H+ + SO4^2- + 2Na+ + 2OH- -> H2SO4 + 2Na+ + 2OH-

4. Sodium Carbonate (Na2CO3): - Molecular Equation: Na2CO3 + 2NaOH -> Na2CO3 + 2NaOH - Ion-Molecular Equation: 2Na+ + CO3^2- + 2Na+ + 2OH- -> Na2CO3 + 2Na+ + 2OH-

Please note that the molecular equations represent the overall reaction, while the ion-molecular equations show the dissociation of the compounds into ions.
