na2so4 + bacl2 = baso4 + 2nacl 2na(+) + so4 (2-) + ba (2+) + > baso4 (осадок) + 2na(+) +

c2h4+cl2=(hv)hcl+c2h3cl

2c2h3cl+2na= 2nacl + c4h10 

c4h10=(pt) ch3-ch2-ch=ch2+h2

ch3-ch2-ch=ch2 + hbr= ch3-ch2-ch2br-ch3

  ch3-ch2-ch2br-ch3 +naoh =(c2h5oh ) ch3-ch=ch-ch3 +nabr +h2o 

ch3-ch=ch-ch3 +br2=ch3-ch2br-ch2br-ch3
