Question

решить цепочку превращений 1). Na-NaH-NaOH-NaAlO2 Na-NaCl-NaOH-NaClO3-NaCl 2). Ba-BaCl2-Ba(OH)2-BaSO4-Ba(HSO4)2-SO2

Answer 1

2na+h2=2nah

nah + h2o= NaOh + H2

NaOH +AlO(OH)=NaAlO2  h2o

 

2Na + 2Hcl= 2NaCl + H2

2NaCl + 2H2O = 2NaOH + Cl2 + H2

6NaOH + 3Cl2 = 5NaClo3 + NaCl + 3H2O

NaClO3 + = Честно,не знаю =)
