Помогите с химией, нужно расставить пропущенные коэффициенты
N2 + O2 = NO
2K + H2 = KH
N2 + H2 = NH3
Al + S = Al2S3
H2 + O2 = H20
Li + O2 = Li20
HI -> H2 + J2
Hg0 -> Hg + O2
HCl = H2 + Cl2
NH3 = N2 + H2
H2O2 = H2O + O2
CuO = Cu2O + O2
CaOH + H3PO4 = Ca3OPO4 + H2O
CH4 + O2 -> CO2 + H2O
Fe2O3 + H2 -> Fe + 3H20
PH3 + O2 -> P2O5 + H2O
Answers & Comments
N₂ + O₂ = 2NO
2K + H₂ = 2KH
N₂ + 3H₂ = 2NH₃
2Al + 3S = Al₂S₃
2H₂ + O₂ = 2H₂0
4Li + O₂ = 2Li₂0
2HI = H₂ + I₂
2HgO = 2Hg + O₂
2HCl = H₂ + Cl₂
2NH₃ = N₂ + 3H₂
2H₂O₂ = 2H₂O + O₂
4CuO = 2Cu₂O + O₂
3Ca(OH)₂ + 2H₃PO₄ = Ca₃(PO₄)₂ + 6H₂O
CH₄ + 2O₂ ⇒ CO₂ + 2H₂O
Fe₂O₃ + 3H₂ = 2Fe + 3H₂O
2PH₃ + 4O₂ = P₂O₅ + 3H₂O
Verified answer
N2 + O2 = 2 NO
2 K + H2 =2 KH
N2 + 3 H2 = 2 NH3
2 Al + 3S = Al2S3
2 H2 + O2 = 2 H20
4 Li + O2 = 2 Li20
2 HI -> H2 + J2
2 Hg0 -> 2 Hg + O2
2 HCl = H2 + Cl2
2 NH3 = N2 + 3 H2
2 H2O2 = 2 H2O + O2
4 CuO = 2 Cu2O + O2
CaOH + H3PO4 = Ca3*OPO*4 + H2O - здесь ошыбка
CH4 + 2 O2 -> CO2 + 2 H2O
Fe2O3 + 3 H2 -> 2Fe + 3H20
2 PH3 + 4 O2 -> P2O5 + 3 H2O
