Question

Ma puteti ajuta cu o problema?

Answer 1

Y                                                                             25,92

Cn(H2O)n+ 2[Ag(NH3)2]OH   →CnH2nOn+1 +    2Ag+     4NH3+H2O

30n                                                                         2X108

 

 

                    3.6n            V1

ALDOZA  Cn(H2O)n + H2   →CnH2n+2On

                    30n             22.4

                 z                    0.92

Cetoza   Cm(H2O)m + H2   →CmH2m+2Om

                30m               22,4

 

 

Y=25.92x30n/2x108

Y=3.6n     aldoza

 

 

V1=22,4x3,6n/30n

V1=2,68 L H2 in reactia cu aldoza

V2=3.6-2.68

V2=0.92

Z=0.92x30m/22.4

Z=1,23 m cetoza

c=mdx100/ms

md=cxms/100

md1=40x54/100

md1=21,6 aldoza

md2=72x10/100

md2=7.2 g

mapa=ms-md

mapa1=ms1-md1

mapa1=40-21.6

mapa1=18.4

mapa2=72-7.2

mapa2=64.8

 

msolutie formata =40+72

msol form=112

112 g…………………….21,6 galdoza……………7.2 g cetoza

 56…………………………..3,6n……………………1,23m

n=21,6x56/112x3,6

n=3 rezulta ca este o trialdoza

m=7.2x56/112x1,23

m=3 deci este si o tricetoza
