Question

AgNO3+FeCl3= Na2S+HCl= K2S+HNO3= Mg(OH)2+H2SO4=

Answer 1

Ответ:

3 AgNO3 + FeCl3 = 3 AgCl + Fe(NO3)3

Na2S + 2 HCl = 2 NaCl + H2S

K2S + 2 HNO3 = 2 KNO3 + H2S

Mg(OH)2 + H2SO4 = MgSO4 + 2 H2O

Answer 2

Let's go through each chemical reaction one by one:

1. AgNO3 + FeCl3: The reaction between silver nitrate (AgNO3) and ferric chloride (FeCl3) results in the formation of silver chloride (AgCl) and ferric nitrate (Fe(NO3)3).

   The balanced chemical equation is: AgNO3 + FeCl3 -> AgCl + Fe(NO3)3

2. Na2S + HCl: When sodium sulfide (Na2S) reacts with hydrochloric acid (HCl), it produces sodium chloride (NaCl) and hydrogen sulfide (H2S) gas.

   The balanced chemical equation is: Na2S + 2HCl -> 2NaCl + H2S

3. K2S + HNO3: The reaction between potassium sulfide (K2S) and nitric acid (HNO3) results in the formation of potassium nitrate (KNO3) and hydrogen sulfide (H2S) gas.

   The balanced chemical equation is: K2S + 2HNO3 -> 2KNO3 + H2S

4. Mg(OH)2 + H2SO4: When magnesium hydroxide (Mg(OH)2) reacts with sulfuric acid (H2SO4), it produces magnesium sulfate (MgSO4) and water (H2O).

   The balanced chemical equation is: Mg(OH)2 + H2SO4 -> MgSO4 + 2H2O

Please note that these equations are balanced and represent the stoichiometric ratios of the reactants and products.
