Помогите решить уравнения реакций:

1) CO + NaOH=(t) HCOONa HCOONa + H2SO4 = HCOOH + NaHSO4 CH3OH + HCOOH = HCOH + CH3OOH HCOH + Н2 = СН3ОН CH3OH+CH3OH=CH3OCH3 +HOH 2)  С4H8O+H2=C4H9OH CH3-CH2-CH2-CH2OH (t,H2SO4 конц) --->H2O + CH2=CH-CH2-CH3 (бутен-1) CH2 = CH - CH2 - CH3 + HBr = CH3 - CHBr - CH2 - CH3 (2-бромбутан) CH3 - CHBr - CH2 - CH3 + NaOH(H2O) = NaBr + CH3-CH2-CHOH-CH3(бутанол-2) 3) Al4C3 + 12HCl → 4AlCl3 + 3CH4 CH₄ + Br₂ →  CH₃Br + HBr 2CH3Br+2Na→ C2H6+2NaBr C2H6→(Ni,t)CH≡CH + 2H₂ C2H2 + 2[Ag(NH3)2]OH→  Ag2C2↓ + 4NH3↑ + 2H2O
