Question

KClO4 + NaNO2 + H2SO4 = Cl2 + NaNo3 + .....    +..... PbO2 + MnCl2 + HNO3 = Pb(NO3)2 + HMnO4 +....  +....

Answer 1

1) 2 KClO₄ + 7 NaNO₂ + H₂SO₄ = Cl₂ + 7 NaNO₃ + K₂SO₄ + H₂O
2) 2 MnCl₂ + 7 PbO₂ + 14 HNO₂ = 2 HMnO₄ + 2 Cl₂ + 7 Pb(NO₃)₂ + 6 H₂O

Answer 2

The balanced chemical equations for the given reactions are as follows:

1. KClO4 + NaNO2 + H2SO4 → Cl2 + NaNO3 + H2O + K2SO4

In this reaction, potassium chlorate (KClO4) reacts with sodium nitrite (NaNO2) and sulfuric acid (H2SO4) to produce chlorine gas (Cl2), sodium nitrate (NaNO3), water (H2O), and potassium sulfate (K2SO4).

2. PbO2 + MnCl2 + HNO3 → Pb(NO3)2 + HMnO4 + H2O + Cl2

In this reaction, lead(IV) oxide (PbO2) reacts with manganese(II) chloride (MnCl2) and nitric acid (HNO3) to produce lead(II) nitrate (Pb(NO3)2), permanganic acid (HMnO4), water (H2O), and chlorine gas (Cl2).

Please note that the products might vary depending on the reaction conditions such as temperature and concentration.
