Уравнения реакции к цепочке 1)метановая кислота углекислый газ 2) кислота

1) 2НСООН + 3О2 = 2СО2 + 2Н2О
2)
СН3Сl + 2Na + CH3Cl => CH3-CH3 
СH3-CH3+Cl2 => CH3-CH2Cl + HCl
CH3-CH2Cl + AgOH  => CH3-CH2OH + AgCl↓
CH3-CH2OH + O =[KMnO4] => CH3-CHO + H2O
CH3-CHO + Ag2O => CH3COOH + 2Ag
CH3OH + CH3COOH => CH3COOCH3 + H2O
CH3COOCH3 + H2O => CH3COOH + CH3OH
