1. H₂+ +SO₃ = H₂SO₃
2. SO₂ + O₃ = SO₃ + O₂
3. Ba + Cl₂ = BaCl₂
4. CaO + H₂O → Ca(OH)₂
5. 2 Zn + O₂ = 2 ZnO
6. 2 Al + 6 H₂O = 2 Al(OH)₃ + 3 H₂
Ответ:
Объяснение:
CH=-CH + 2H2 -> CH3-CH3 (t, kat)
CH3-CH3 + Cl2 -> CH3-CH2-Cl + HCl (hy)
СH3-CH2-Cl + NaOH = CH3-CH2-OH + NaCl (t)
==>Ca(OH)2+H2................
M(чист)=20*0.45=9г
m(чист) = 10*0.35= 3.5 г
m(общ) = 9+3.5= 12.5 г
ω= 12.5/30=0.417*100%=41.7%
