Os dois processos produtivos mais utilizados na produção de transformados plásticos são a extrusão (62%) e a moldagem por injeção (30%). O processamento dos polímeros acontece em temperaturas altas para que ocorra sua fusão. Observe a reação envolvendo a produção de polímeros orgânicos: H
|
n CH2= CHcatalisador -CH2 -C -
X |
X n
Onde X poder ser H, grupos orgânicos alifáticos e aromáticos ou halogênios. Dos compostos orgânicos cujas fórmulas são fornecidas a seguir:
(1) CH = CH2 (2) H2C = CH2
(3) H2C - CH3 (4) H2C = CH
Cl CN
Podem sofrer polimerização pelo processo descrito:
(A) 1, apenas.
(B) 3, apenas.
(C) 1 e 2, apenas.
(D) 1, 2 e 4, apenas.
(E) 2, 3 e 4, apenas.

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
