Question

CaO+SO3=?SO2+H2O=?Na2O+HCI=?MgO+H2SO4=??+H2SO4=Al(HSO4)Na2O+HCI=?​

Answer 1

Ответ:

CaO+SO3=CaSO4

SO2+H2O=H2SO3

Na2O+HCl=2NaCl+H2O

MgO+H2SO4=MgSO4+H2O

Na2O+2HCl=2NaCl+H2O

Al2O3+3H2SO4=Al2(SO4)3+3H2O

Answer 2

Let's break down the chemical reactions you provided:

1. CaO + SO3 → ? The reaction between calcium oxide (CaO) and sulfur trioxide (SO3) forms calcium sulfate (CaSO4): CaO + SO3 → CaSO4

2. SO2 + H2O → ? The reaction between sulfur dioxide (SO2) and water (H2O) produces sulfurous acid (H2SO3): SO2 + H2O → H2SO3

3. Na2O + HCl → ? The reaction between sodium oxide (Na2O) and hydrochloric acid (HCl) results in sodium chloride (NaCl) and water (H2O): Na2O + 2HCl → 2NaCl + H2O

4. MgO + H2SO4 → ? The reaction between magnesium oxide (MgO) and sulfuric acid (H2SO4) forms magnesium sulfate (MgSO4): MgO + H2SO4 → MgSO4 + H2O

5. ? + H2SO4 → Al(HSO4)3 To produce aluminum bisulfate (Al(HSO4)3), we need a compound containing aluminum reacting with sulfuric acid.

6. Na2O + HCl → ? The reaction between sodium oxide (Na2O) and hydrochloric acid (HCl) results in sodium chloride (NaCl) and water (H2O): Na2O + 2HCl → 2NaCl + H2O

Please note that the question mark in reaction 5 indicates an unknown compound containing aluminum that would react with sulfuric acid to form aluminum bisulfate.
