Question

ZnO+ NaOH=? PbO+HNO3=? AL2O3+H2O=? Na2O+H2O=? CaO+CO2=? CaO+CO2=? SiO2+H2O=? CO2+Fe(OH)=?

Answer 1

ZnO+ 2NaOH=Zn(OH)2+Na2O

PbO+2HNO3=Pb(NO3)2+H2O

AL2O3+H2O=Al2O3 + H2O

Na2O+H2O=Na2O+H2O

 

 

Answer 2

ZnO + NaOH = ?

When zinc oxide (ZnO) reacts with sodium hydroxide (NaOH), it forms sodium zincate (Na2ZnO2).

PbO + HNO3 = ?

When lead(II) oxide (PbO) reacts with nitric acid (HNO3), it forms lead(II) nitrate (Pb(NO3)2).

AL2O3 + H2O = ?

When aluminum oxide (Al2O3) reacts with water (H2O), it forms aluminum hydroxide (Al(OH)3).

Na2O + H2O = ?

When sodium oxide (Na2O) reacts with water (H2O), it forms sodium hydroxide (NaOH).

CaO + CO2 = ?

When calcium oxide (CaO) reacts with carbon dioxide (CO2), it forms calcium carbonate (CaCO3).

SiO2 + H2O = ?

When silicon dioxide (SiO2) reacts with water (H2O), it forms silicic acid (H2SiO3).

CO2 + Fe(OH) = ?

Carbon dioxide (CO2) does not react with iron(III) hydroxide (Fe(OH)3).
