Answer:

37%

Explanation:

From the question, the equation goes does.

C2H6+ (1-x)+a(O2+3.76N2)=bC02 + cH2O + axO2 + 3.76dN2.

Mair=Mair/Rin

( MN)O2 + (MN)N2÷ (MN)O2 + (MN)N2 +(MN)C2H6.

33 . 3.25(1-x) + 28 × 13.16(1-x) ÷ 33 × 3.25(1-x) + 28 × 13.16(1-x). + 30.1

= 176/176+8

X= 0.37

0.37 × 100

X= 37%

Winston predicts that certain people will be vaporized and that certain people will never be vaporized. Who? Why?
Margarita [4]

Answer:

Hi

One of the most famous works George Orwell shows us in 1984 a society that is controlled by the Superstate, in such a way that the inhabitants cannot do or say anything without The Big Brother finding out. If anyone tries to oppose this system, it is vaporized and in less than three days society forgets that there was a person who conspired or worse, that existed.

The detentions happened at night. He woke up startled because one hand shook one shoulder, a flashlight focused on him and a circle of grim faces appeared around the bed. In most cases there was no process. People disappeared and always during the night. The name of the individual in question disappeared from all the records, any reference to what he had done was erased from everywhere and his passage through life was completely annulled as if he had never existed.
