2 NO3 + 3 C = N2 + 3 CO2
C10H18O + O = CO2 + H2O =>
C10H18O + 28 O = 10 CO2 + 9 H2O
Li + Br2 = LiBr =>
2 Li + Br2 = 2 LiBr
Cu + H2O = CuO + H2 = =>
Cu + H2O = CuO + H2
MgNaOH = NaMg(OH) =>
MgNaOH = NaMg(OH)
Ca + H2O = Ca(OH)2 + H23 =>
23 Ca + 46 H2O = 23 Ca(OH)2 + 2 H23
Cu(NO3)2 + NaCl = Cu(Cl)2 + NaNO3 =>
Cu(NO3)2 + 2 NaCl = Cu(Cl)2 + 2 NaNO3
K2S + K2MnO4 + H2O = MnO(OH)2 + S + KOH =>
K2S + K2MnO4 + 3 H2O = MnO(OH)2 + S + 4 KOH
Sr + Br2 = SrBr2 =>
Sr + Br2 = SrBr2
K2O + HNO3 = H2O + KNO3 =>
K2O + 2 HNO3 = H2O + 2 KNO3
LiOH + HSO4 = LiSO4 + HOH =>
LiOH + HSO4 = LiSO4 + HOH
Cu2S + ZnS = CuS + Zn =>
Cu2S + ZnS = 2 CuS + Zn
