Balancing Chemical Equations and Identifying Reaction Types

To balance the chemical equations and identify the reaction types, let's go through each equation one by one.

1. KOH + H2SO4 = K2SO4 + H2O - This is a neutralization reaction, where an acid (H2SO4) reacts with a base (KOH) to form a salt (K2SO4) and water (H2O) [[1]].

2. Fe(OH)3 + HCl = FeCl3 + H2O - This is also a neutralization reaction, where an acid (HCl) reacts with a base (Fe(OH)3) to form a salt (FeCl3) and water (H2O) [[2]].

3. AgNO3 + Cu = Cu(NO3)2 + Ag - This is a single displacement reaction, where a more reactive metal (Cu) displaces a less reactive metal (Ag) from its compound (AgNO3), forming a new compound (Cu(NO3)2) and releasing the displaced metal (Ag) [[3]].

4. NO + O2 = NO2 - This is a synthesis reaction, where two elements (NO and O2) combine to form a compound (NO2) [[4]].

5. N2O5 = NO2 + O2 - This is a decomposition reaction, where a compound (N2O5) breaks down into simpler substances (NO2 and O2) [[5]].

6. MnO2 + C = Mn + CO - This is a redox reaction, where manganese dioxide (MnO2) reacts with carbon (C) to form manganese (Mn) and carbon monoxide (CO) [[6]].

7. Fe2O3 + H2 = Fe + H2O - This is a redox reaction, where iron(III) oxide (Fe2O3) reacts with hydrogen gas (H2) to form iron (Fe) and water (H2O) [[7]].

8. N2O5 + H2O = HNO3 - This is a synthesis reaction, where a compound (N2O5) reacts with water (H2O) to form nitric acid (HNO3) [[8]].

9. Al + HCl = AlCl3 + H2 - This is a single displacement reaction, where aluminum (Al) displaces hydrogen from hydrochloric acid (HCl), forming aluminum chloride (AlCl3) and releasing hydrogen gas (H2) [[9]].

10. Mg + SiO2 = MgO + Si - This is a redox reaction, where magnesium (Mg) reacts with silicon dioxide (SiO2) to form magnesium oxide (MgO) and silicon (Si) [[10]].

11. H2O2 = H2O + O2 - This is a decomposition reaction, where hydrogen peroxide (H2O2) breaks down into water (H2O) and oxygen gas (O2) [[11]].

12. Cr + O2 = Cr2O3 - This is a synthesis reaction, where chromium (Cr) reacts with oxygen gas (O2) to form chromium(III) oxide (Cr2O3) [[12]].

13. CrO3 = Cr2O3 + O2 - This is a decomposition reaction, where chromium(VI) oxide (CrO3) breaks down into chromium(III) oxide (Cr2O3) and oxygen gas (O2) [[13]].

14. KBrO3 = KBr + O2 - This is a decomposition reaction, where potassium bromate (KBrO3) breaks down into potassium bromide (KBr) and oxygen gas (O2) [[14]].
