Balance the equation Sb() + O2() --> Sb2O3(9)

Answer 1

4) NaBH4 + BF3 - NaBF4 + B2H6 3 NaBH4 + 4 BF3 3 NaBF4 + 2 B2H6 MgCl2 + K3PO4 — Mg3(PO4)2 + KCI 3 MgCl2 + 2 K3PO4 - C6H14 + O2 2 C6H14 + 19 02 6 KCI + Mg3(PO4)2 CO2 + H20 12 CO2 + 14 H2O 7) As2O3(s) + Ca(OH)2(aq) Caz(AsO4)2(s) + H2O(1) 3 As2O3 + 15 Ca(OH)2 5 Ca3 + 3 (AsO4)2 + 15 H2O 8) Mg(OH)2(aq) + HBr (aq) MgBr2(aq) + H2O(0) Mg(OH)2(aq) + 2 HBr(aq) MgBr2(aq) + 2 H20(1) 9) Sb(s) + O2(g) Sb2O3(s) 4 Sb(s) + 3 O2(g) - 2 Sb2O3(s) The above equations are balance equations .Reactants of atoms are equal to products of atoms.
