Question

Complete and balance the following:-
1.) Na+H2O=
2.) PbCO3 (heat) =
3.) Pb(NO3)2 (heat) =
4.) Na2O+H2SO4=
​

Answer 1

Hello sis

Your answer:

1. 2Na + 2H₂O → 2NaOH + H₂

2. PbCO₃ → PbO + CO₂

3. 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂

4. Na₂O + H₂SO₄ → Na₂SO₄ + H₂O

Answer 2

Answer:

$\huge \: required \: answer$

1) 2Na²+2H2O=>2NaOH+H2

2) PbCO3+PbO+CO2

3)2Pb(NO3)2=>2PbO+4NO2+O2

4)NA2O+H2SO4=>Na2SO4+H2O
