Question

Сu+FeSO4= Ba+HNO(p)= Fe+CuCl2= Na2O+H2O= K+O2= Ba+H2O= Ag+HNO3(k)= Cu+HCl=

Answer 1

Сu+FeSO4= нет реакции4Ba+ 10HNO3(p)= 4Ba(NO3)2 + NH4NO3 + 3H2O
Fe+CuCl2= FeCl2 + Cu
Na2O+H2O= 2NaOH
K+O2= KO2
Ba+ 2H2O= Ba(OH)2 + H2
Ag+ 2HNO3(k)= AgNO3 + NO2 + H2O
Cu+HCl= нет реакции

Answer 2

Chemical Reactions:

1. Cu + FeSO4 = Fe + CuSO4: - This is a single displacement reaction where copper (Cu) displaces iron (Fe) from iron(II) sulfate (FeSO4) to form copper(II) sulfate (CuSO4) and iron (Fe).

2. Ba + HNO(p) = Ba(NO3)2 + H2: - This is a double displacement reaction where barium (Ba) reacts with nitric acid (HNO3) to form barium nitrate (Ba(NO3)2) and hydrogen gas (H2).

3. Fe + CuCl2 = Cu + FeCl2: - This is a single displacement reaction where iron (Fe) displaces copper (Cu) from copper(II) chloride (CuCl2) to form copper (Cu) and iron(II) chloride (FeCl2).

4. Na2O + H2O = 2NaOH: - This is a combination reaction where sodium oxide (Na2O) reacts with water (H2O) to form sodium hydroxide (NaOH).

5. K + O2 = K2O: - This is a combination reaction where potassium (K) reacts with oxygen (O2) to form potassium oxide (K2O).

6. Ba + H2O = Ba(OH)2 + H2: - This is a single displacement reaction where barium (Ba) reacts with water (H2O) to form barium hydroxide (Ba(OH)2) and hydrogen gas (H2).

7. Ag + HNO3(k) = AgNO3 + NO2 + H2O: - This is a single displacement reaction where silver (Ag) reacts with nitric acid (HNO3) to form silver nitrate (AgNO3), nitrogen dioxide (NO2), and water (H2O).

8. Cu + HCl = CuCl2 + H2: - This is a single displacement reaction where copper (Cu) reacts with hydrochloric acid (HCl) to form copper(II) chloride (CuCl2) and hydrogen gas (H2).
