Question

CO₂ + NaOH = H₂O + SiO₂ =CuO + HCI= SO₂ + KOH=MgO + H₂SO4 = CuO + H₂O =NO₂ + H₂O =CO₂ + SiO₂ =H₂O + K₂O =FeO + HNO3 =N₂O5 + SO3=​

Answer 1

CO2 + 2NaOH = Na2CO3 + H2O

SiO2 + H2O → H2SiO3
CuO+Hcl=CuCl2+H2O
SO2+2KOH=K2SO3+H2O
MgO+H2SO4=H2O+MgSO4
CuO+H2O=Cu(OH)2
2no2+H2O=HNO2+HNO3
CO2+SiO2=Si2CO3+O2
K2O+H2O=KOH
FeO + HNO3 = Fe(NO3)2 + H2O
SO3 + N2O5 = N2(SO4)5

Answer 2

Let's go through each chemical equation step by step:

1. CO₂ + NaOH = H₂O + Na₂CO₃ Carbon dioxide reacts with sodium hydroxide to form water and sodium carbonate.

2. SiO₂ + CuO + 2HCl = CuCl₂ + H₂O Silicon dioxide and copper(II) oxide react with hydrochloric acid to produce copper(II) chloride and water.

3. SO₂ + 2KOH = K₂SO₃ + H₂O Sulfur dioxide reacts with potassium hydroxide to form potassium sulfite and water.

4. MgO + H₂SO₄ = MgSO₄ + H₂O Magnesium oxide reacts with sulfuric acid to produce magnesium sulfate and water.

5. CuO + H₂O = Cu(OH)₂ Copper(II) oxide reacts with water to form copper(II) hydroxide.

6. NO₂ + H₂O = HNO₃ Nitrogen dioxide reacts with water to produce nitric acid.

7. CO₂ + SiO₂ = No reaction Carbon dioxide and silicon dioxide do not react with each other.

8. H₂O + K₂O = 2KOH Water reacts with potassium oxide to form potassium hydroxide.

9. FeO + 2HNO₃ = Fe(NO₃)₂ + H₂O Iron(II) oxide reacts with nitric acid to produce iron(II) nitrate and water.

10. N₂O₅ + SO₃ = HNO₃ Dinitrogen pentoxide reacts with sulfur trioxide to produce nitric acid.

It's important to note that the equations provided assume the reactions are occurring under appropriate conditions (e.g., proper temperature and pressure) and are balanced.
