Answer 1

C6H6 + CH2=CH-CH3 -> C6H5-CH(CH3)2 [cumen] - (-H2) --> C6H5-C(CH3)=CH2

nxCH2=CH-CH=CH2 + nyC6H5-C(CH3)=CH2 --> [-CH2-CH=CH-CH2-]x-[-C6H5-C(CH3)-CH2-]y]n

b) C4H6 + 11/2O2 => 4CO2 + 3H2O + Q

C9H10 + 23/2O2 => 9CO2 + 5H2O + Q

54x+118y......................................54x+90y
 15,92............................................13,68              

738,72x+1614,24y = 859,68x+1432,8y => 120,96x=181,44y => x/y = 3/2

raport molar monomeri => 3:2

c) 0,9*0,95*0,8*1592 = 1088,928g ..
