Какую массу naoh и v2o5 нужно сплавить,чтобы получить 5 г navo3? какая масса водяных паров при этом улетучится? ​

2. na₂co₃+2hcl=2nacl+co₂ (газ)  +h₂o 3. zno+2hno₃ =zn(no₃)₂+h₂o 4. k₂sio₃+h₂so₄=k₂so₄+h₂sio₃ (осад) 5. bao + 2hno₃ = ba(no₃)₂+h₂o 6. k₂o + h₂o = 2koh 7. cao + sio₂ = casio₃ 8. naoh + hcl = nacl + h₂o 9. cu(oh)₂  +  2hcl = cucl₂ + 2h₂o 10. 3ba(oh)₂ + 2fe(no₃)₃ = 3ba(no₃)₂ + 2fe(oh)₃ (осад) 11. p₂o₅ + 6koh =    2k₃po₄ + 3h₂o 12. 2cuoh = cu₂o + h₂o 13. bacl₂ + na₂so₄ = baso₄ (осад) + 2nacl 14. cu + 2agno₃ = cu(no₃)₂ + 2ag 15. 6koh + al₂(so₄)₃ =3 k₂so₄ + 2al(oh)₃ (осад) 16. 2al + 3cl₂ = 2alcl₃

1. C2H6 + Br2 = C2H5Br + HBr
C2H5Br + NaOH = C2H5OH + NaBr
C2H5OH + CH3COOH ---(H2SO4)---> CH3COOC2H5 + H2O
CH3COOC2H5 + NaOH = CH3COONa + C2H5OH
CH3COONa + NaOH + t (сплав) = CH4 + Na2CO3  CH4 + t = C2H2
C2H2 + HCl = CH2=CH-Cl    nCH2=CH-Cl = [-CH2-CH(Cl)-]n

2. CH3COOCH3 ---(NaOH/H2O)---> CH3COONa + CH3OH
CH3OH + O2 ---(V2O5/t)---> HCOH + H2O
HCOH + [Ag(NH3)2]OH = Ag + HCOOH + H2O + 2NH3
HCOH ---(H2/Ni)---> CH3OH
CH3OH + C2H5COOH ---(H2SO4)---> C2H5COOCH3 + H2O
C2H5COOCH3 + NaOH (водн) = C2H5COONa + CH3OH
C2H5COONa + NaOH + t (сплав) = C2H6 + Na2CO3

3. C3H7OH ---(Cu/t)---> C2H5CHO + H2
C2H5CHO + Cu(OH)2 = C2H5COOH + Cu2O
C2H5COOH + C2H5OH ---(H2SO4)---> C2H5COOC2H5
C2H5COOC2H5 + NaOH (водн) = C2H5COONa + C2H5OH
