Question

Ma puteti ajuta va rog??

Answer 1

CH2=CH-CH3 + cL2---> CH2=CH-CH2Cl + HCl

CH2=CH-CH2Cl+ KCN---> CH2=CH-CH2-CN+KCl

CH2=CH-CH2-CN+3H2---> CH3-CH2-CH2-CH2-NH2

CH3-CH2-CH2-CH2-NH2 +HONO----> CH3-CH2-CH2-CH2OH+H2O+N2

CH3-CH2-CH2-CH2OH+ 2O----> CH3-CH2-CH2-COOH +H2O

calculez masa si moli butanol

c=mdx1oo/ms= mdx100/v,sxro----> md= 20x1000x1,04/20g=208g C4H10O

niu=m/M=208g/74g/mol= 2,8mol butanol

niu,O= 2x2,8mol= 5,6mol     din ultima reactie

2KMno4+3H2SO4---> K2SO4+2MnSO4 +3H2O+5O

2mol...................................................................................5mol

x..............................................................................................5,6mol

x=2,24molKMnO4

c,m= niu/V--->V= 2,24/1  L= 2,24 L
