Question

CaO+CO2= FeO+SiO2= NaOH+P2O5= SO3+Ba(OH)2= SO3+NaOH=NaSO4+ ..... P2O5+H2O=

Answer 1

CaO+CO2=СaCO3 FeO+SiO2= FeSiO3
6NaOH+P2O5=2Na3PO4+3H2O
SO3+Ba(OH)2=BaSO4+H2O
SO3+2NaOH=Na2SO4+ H2O
P2O5+3H2O=2H3PO4

Answer 2

CaO + CO2 = CaCO3 This is a chemical reaction in which calcium oxide (CaO) reacts with carbon dioxide (CO2) to form calcium carbonate (CaCO3).

FeO + SiO2 = FeSiO3 This is a chemical reaction in which iron(II) oxide (FeO) reacts with silicon dioxide (SiO2) to form iron(III) silicate (FeSiO3).

2NaOH + P2O5 = 2NaPO3 + H2O This is a chemical reaction in which two molecules of sodium hydroxide (NaOH) react with phosphorus pentoxide (P2O5) to form two molecules of sodium metaphosphate (NaPO3) and water (H2O).

SO3 + Ba(OH)2 = BaSO4 + H2O This is a chemical reaction in which sulfur trioxide (SO3) reacts with barium hydroxide (Ba(OH)2) to form barium sulfate (BaSO4) and water (H2O).

SO3 + 2NaOH = Na2SO4 + H2O This is a chemical reaction in which sulfur trioxide (SO3) reacts with two molecules of sodium hydroxide (NaOH) to form sodium sulfate (Na2SO4) and water (H2O).

P2O5 + 3H2O = 2H3PO4 This is a chemical reaction in which phosphorus pentoxide (P2O5) reacts with three molecules of water (H2O) to form two molecules of phosphoric acid (H3PO4).
