Question

Na2SiO3+HCL= K2CO+HNO3= Mg(NO3)2+HCL= Na+H2O= NaOH+HNO3=

Answer 1

Ответ:

1.Na2SiO3 +2 HCl =H2SiO3 +2NaCl

2.K2CO+2HNO3= CO2 +H2O +2KNO3

Mg(NO3)2+HCL=реакция не идет, так как не образуется ни газа, ни воды ни осадка

2Na+2H2O= 2NaOH +H2

NaOH+HNO3= NaNO3 +H2O

Answer 2

Let's break down the given chemical equations one by one:

1. Na2SiO3 + HCl: This equation represents the reaction between sodium silicate (Na2SiO3) and hydrochloric acid (HCl). The balanced equation for this reaction is: Na2SiO3 + 2HCl → 2NaCl + H2SiO3

2. K2CO + HNO3: The given equation seems to have a typographical error. The correct formula for potassium carbonate is K2CO3. Assuming this is the intended compound, the balanced equation for the reaction between potassium carbonate and nitric acid (HNO3) is: K2CO3 + 2HNO3 → 2KNO3 + H2O + CO2

3. Mg(NO3)2 + HCl: This equation represents the reaction between magnesium nitrate (Mg(NO3)2) and hydrochloric acid (HCl). The balanced equation for this reaction is: Mg(NO3)2 + 2HCl → 2HNO3 + MgCl2

4. Na + H2O: The given equation is incomplete. Sodium (Na) is a reactive metal, and it readily reacts with water (H2O). The balanced equation for this reaction is: 2Na + 2H2O → 2NaOH + H2

5. NaOH + HNO3: This equation represents the reaction between sodium hydroxide (NaOH) and nitric acid (HNO3). The balanced equation for this reaction is: NaOH + HNO3 → NaNO3 + H2O

Please note that the coefficients in these balanced equations represent the stoichiometric ratios between the reactants and products.
