Mr(CO2) = 44
Mr(N2O) = 44
W(N) = Ar(N) * n / Mr(N2O) *100% = 14 *2 / 44 *100% = 64%
KO2 + 3K = 2K2O
K2O + H2O = 2KOH
KOH + HCl = KCl + H2O
1) HS-CH₂-CH(NH₂)-COOH
2) (NH₂)₂CO + 2HNO₂ = 2N₂ + CO₂ + 3H₂O
3) C₆H₅NH₂ + (CH₃CO)₂O --> C₆H₅NH-(O)C-CH₃ + CH₃COOH
4) (C₂H₅)₂NH + HCl = (C₂H₅)₂NH₂⁺Cl⁻
5) CH₃-CH(NH₂)-COOH + HCl = ⁻Cl⁺H₃N-CH(CH₃)-COOH
CH₃-CH(NH₂)-COOH + NaOH = CH₃-CH(NH₂)-COONa + H₂O
CH₃-CH(NH₂)-COOH + C₂H₅OH = CH₃-CH(NH₂)-COOC₂H₅ + H₂O
6)
H₂N-CH₂-COOH + CH₃-CH(NH₂)-COOH -->
--> H₂N-CH₂-C(O)-NH-CH(CH₃)-COOH
