Question

Na2 O + H2 SO4= ? Fe2 O3 + H Cl =? Mg O + H Cl =? P2 O5 + Na OH =? Si O2 + K OH =? SO3 + Ba (OH)2 =?

Answer 1

Na2O + H2SO4 = Na2SO4 + H2O

Fe2O3 + 6HCl(газ) = 2FeCl3 + 3H2O

MgO + 2HCL = MgCL2 + H2O

6NaOH + P2O5 = 2Na3PO4 + 3H2O

SiO2 + 2KOH = K2SiO3 + H2O

Ba(OH)2 + 2SO3 = Ba(HSO4)2

 

 

 

Answer 2

Chemical Reactions:

Na2O + H2SO4 = ?

The reaction between sodium oxide (Na2O) and sulfuric acid (H2SO4) results in the formation of sodium sulfate (Na2SO4) and water (H2O). ``` Na2O + H2SO4 → Na2SO4 + H2O ```

Fe2O3 + HCl = ?

When iron(III) oxide (Fe2O3) reacts with hydrochloric acid (HCl), it forms iron(III) chloride (FeCl3) and water (H2O). ``` Fe2O3 + 6HCl → 2FeCl3 + 3H2O ```

MgO + HCl = ?

The reaction between magnesium oxide (MgO) and hydrochloric acid (HCl) produces magnesium chloride (MgCl2) and water (H2O). ``` MgO + 2HCl → MgCl2 + H2O ```

P2O5 + 2NaOH = ?

Phosphorus pentoxide (P2O5) reacts with sodium hydroxide (NaOH) to form sodium phosphate (Na3PO4). ``` P2O5 + 3NaOH → 2Na3PO4 + 3H2O ```

SiO2 + 2KOH = ?

The reaction between silicon dioxide (SiO2) and potassium hydroxide (KOH) results in the formation of potassium silicate (K2SiO3) and water (H2O). ``` SiO2 + 2KOH → K2SiO3 + H2O ```

SO3 + Ba(OH)2 = ?

Sulfur trioxide (SO3) reacts with barium hydroxide (Ba(OH)2) to produce barium sulfate (BaSO4). ``` SO3 + Ba(OH)2 → BaSO4 + H2O ```
