Question

complete and balance the equation ........



who said the correct answers I will mark as brainlist...... really it's true.....​

Answer 1

Al₂O₃+ 3C + N₂ → 2AlN + 3CO

Pb(NO₃)₂ → PbO + NO₂ + O₂

NO₂+ O₃ → N₂O₅ + O₂

Ca(OH)₂ + NH₄Cl → CaCl₂ + NH₃ + H₂O

HNO₃ → NO₂ + O₂ + H₂O

Answer 2

i..Al2O3 + 3C + N2 = 2AlN + 3CO

ii...2 Pb(NO3)2 (s) → 2 PbO (s) + 4 NO2 (g) + O2 (g)

iii.2NO2 + O3 = N2O5 + O2

iv..Ca(OH)2 + NH4Cl = CaCl2 + NH3 + H2O.

v...4HNO3 = 4NO2 + O2 + 2H2O
