Ответы

Автор ответа: god91

$C_nH_{2n-2}$ -общая формула алкадиенов

M( $C_nH_{2n-2}$ )=12n+2n-2=(14n-2)г/моль

M(алкадиена)=D*M( $CO_2$ )=2.5*44=110г/моль

значит 14n-2=110

n=8

формула его $C_8H_{14}$

William Shakespeare is the most famous writer in human history. His literature language is the masterpiece of world linguistic culture. His English was newly created English language. He was born in Stratford-on-Avon, a small town in the middle of England. His father and mother wanted their son to be an educated boy so William was interested in reading. William liked nature. He adore being watching the river Avon. Those days there were not so many theatres and circuses in English towns. Theatre workers travelled moving from one place to another with their interesting shows and plays. They always visited Stratford-on-Avon. William was really amused by watching their play. Then he chose to be an actor.
