Answer 1

1) 2AgNO3+BaCl2=2AgCl+Ba(NO3)2
2Ag+2NO3+Ba+2Cl=2AgCl+Ba+2NO3
Ag+Cl=AgCl

Answer 2

1) AgNO3 + BaCl2

The reaction between silver nitrate (AgNO3) and barium chloride (BaCl2) can be represented by the following balanced ionic equation:

2AgNO3 + BaCl2 → 2AgCl + Ba(NO3)2 [[1]]

In this reaction, silver nitrate reacts with barium chloride to form silver chloride and barium nitrate.

2) AgNO3 + CaCl2

The reaction between silver nitrate (AgNO3) and calcium chloride (CaCl2) can be represented by the following balanced ionic equation:

2AgNO3 + CaCl2 → 2AgCl + Ca(NO3)2 [[2]]

In this reaction, silver nitrate reacts with calcium chloride to form silver chloride and calcium nitrate.

3) HCl + CaCO3

The reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) can be represented by the following balanced molecular equation:

2HCl + CaCO3 → CaCl2 + H2O + CO2 [[3]]

In this reaction, hydrochloric acid reacts with calcium carbonate to form calcium chloride, water, and carbon dioxide.

4) Na2SO4 + CaCO3

The reaction between sodium sulfate (Na2SO4) and calcium carbonate (CaCO3) can be represented by the following balanced molecular equation:

Na2SO4 + CaCO3 → Na2CO3 + CaSO4 [[4]]

In this reaction, sodium sulfate reacts with calcium carbonate to form sodium carbonate and calcium sulfate.

5) Na2SO4 + BaCl2

The reaction between sodium sulfate (Na2SO4) and barium chloride (BaCl2) can be represented by the following balanced molecular equation:

Na2SO4 + BaCl2 → BaSO4 + 2NaCl [[5]]

In this reaction, sodium sulfate reacts with barium chloride to form barium sulfate and sodium chloride.

6) K2CO3 + CaCl2

The reaction between potassium carbonate (K2CO3) and calcium chloride (CaCl2) can be represented by the following balanced molecular equation:

K2CO3 + CaCl2 → CaCO3 + 2KCl [[6]]

In this reaction, potassium carbonate reacts with calcium chloride to form calcium carbonate and potassium chloride.

7) AgNO3 + CaCl2

The reaction between silver nitrate (AgNO3) and calcium chloride (CaCl2) can be represented by the following balanced ionic equation:

AgNO3 + CaCl2 → AgCl + Ca(NO3)2 [[7]]

In this reaction, silver nitrate reacts with calcium chloride to form silver chloride and calcium nitrate.

8) Ba(NO3)2 + H2S

The reaction between barium nitrate (Ba(NO3)2) and hydrogen sulfide (H2S) can be represented by the following balanced molecular equation:

Ba(NO3)2 + H2S → BaS + 2HNO3 [[8]]

In this reaction, barium nitrate reacts with hydrogen sulfide to form barium sulfide and nitric acid.

9) Cu + HNO3 + Ba(NO3)2

The reaction between copper (Cu), nitric acid (HNO3), and barium nitrate (Ba(NO3)2) can be represented by the following balanced molecular equation:

Cu + 4HNO3 + Ba(NO3)2 → Cu(NO3)2 + Ba(NO3)2 + 2H2O + NO [[9]]

In this reaction, copper reacts with nitric acid and barium nitrate to form copper nitrate, barium nitrate, water, and nitrogen monoxide.
