Question

H3PO4+ CuO= Ag+H3PO4= Na2CO3 + HNO3 = Pb(NO3)2 ---> P2O5+ Ba(OH)2= Na2SiO3+HNO3=

Answer 1

2H₃PO₄+ 3CuO=Cu₃(PO₄)₂↓+3H₂O

Ag+H₃PO₄≠

Na₂CO₃ + 2HNO₃ =2NaNO₃+CO₂↑+H₂O

2Pb(NO₃)₂ =2PbO+4NO₂↑+O₂↑

P₂O₅+ 3Ba(OH)₂=Ba₃(PO₄)₂↓+3H₂O

Na₂SiO₃+2HNO₃=2NaNO₃+H₂SiO₃↓

Answer 2

Answer 3

H3PO4 + CuO = Cu(H2PO4)2 In this reaction, phosphoric acid (H3PO4) reacts with copper(II) oxide (CuO) to form copper dihydrogen phosphate (Cu(H2PO4)2). The balanced equation for this reaction is:

2 H3PO4 + 3 CuO = Cu(H2PO4)2 + 3 H2O

Ag + H3PO4 = Ag3PO4 + H2 In this reaction, silver (Ag) reacts with phosphoric acid (H3PO4) to form silver phosphate (Ag3PO4) and hydrogen gas (H2). The balanced equation for this reaction is:

3 Ag + H3PO4 = Ag3PO4 + 3 H2

Na2CO3 + HNO3 = NaNO3 + CO2 + H2O In this reaction, sodium carbonate (Na2CO3) reacts with nitric acid (HNO3) to form sodium nitrate (NaNO3), carbon dioxide (CO2), and water (H2O). The balanced equation for this reaction is:

Na2CO3 + 2 HNO3 = 2 NaNO3 + CO2 + H2O

Pb(NO3)2 + 2 NaOH = Pb(OH)2 + 2 NaNO3 In this reaction, lead(II) nitrate (Pb(NO3)2) reacts with sodium hydroxide (NaOH) to form lead(II) hydroxide (Pb(OH)2) and sodium nitrate (NaNO3). The balanced equation for this reaction is:

Pb(NO3)2 + 2 NaOH = Pb(OH)2 + 2 NaNO3

P2O5 + 3 Ba(OH)2 = 2 Ba3(PO4)2 + 3 H2O In this reaction, phosphorus pentoxide (P2O5) reacts with barium hydroxide (Ba(OH)2) to form barium phosphate (Ba3(PO4)2) and water (H2O). The balanced equation for this reaction is:

P2O5 + 3 Ba(OH)2 = 2 Ba3(PO4)2 + 3 H2O

Na2SiO3 + 2 HNO3 = 2 NaNO3 + H2SiO3 In this reaction, sodium silicate (Na2SiO3) reacts with nitric acid (HNO3) to form sodium nitrate (NaNO3) and silicic acid (H2SiO3). The balanced equation for this reaction is:

Na2SiO3 + 2 HNO3 = 2 NaNO3 + H2SiO3
