2Сs + 2H₂O = 2CsOH + H₂
L₂O + H₂O = 2LiOH
Na₂O + SO₂ = Na₂SO₃
CrO + H₂O = Cr(OH)₂
N₂O₅ + H₂O = 2HNO₃

Тут их 2 соли. NaCL и СаСL2
H2O2
W (H)= Ar (H)*2/Mr (H2O2)*100%
W (H)= 2/34*100%= 5.88%
Ответ: 5.88%
CaC2+2H2O=CH---CH+Ca(OH)2
CH---CH+H2=CH2--CH2
CH2--CH2+Br2=CH3-CH2-Br+HBr
CH3-CH2-Br+CH3-CH2-Br+Na=2CH3-CH2-CH2-CH2+2NaBr
