Question

va rog ...frumos ..toate subpunctele dar accent mai mult pe c si d

Answer 1

n=m/M=11,8/59=0,2 moli s.o

MCO2=44g/mol

44g CO2.................12g C
26,4g CO2..............x=7,2g C

MH2O=18g/mol

18g H2O...................2g H2
16,2g H2O.................x=1,8g H2

m N=11,8-7,2-1,8=2,8g

n=m/M=7,2/12=0,6 moli C

n=m/M=1,8/2=0,9 moli H2

n=m/M=2,8/14=0,2 moli N

0,2 moli s.o.................0,6 moli C.............0,9 moli H2.......0,2 moli N
1 mol..........................x=3 atomi C...........y=9 atomi H.......z=1 atom N

F.M=>C3H9N

d. CH3-NH-CH2-CH3 sau CH3-CH2-CH2-NH2

CH3-N-CH3

        CH3
