Объяснение:

Станол (C18H36) - це жирний спирт (алканол) з масою 284 г/моль.

Гідроген бромід (HBr) - це кислота з масою 80,91 г/моль.

Треба зауважити, що станол реагує з гідроген бромідом в присутності каталізатора, такого як хлорид цинку (ZnCl2), та нагрівається, утворюючи бромід станцю (C18H35Br) та воду (H2O).

У реакції з гідроген бромідом, важливо врахувати, що станол (C18H36) та гідроген бромід (HBr) мають різну стехіометрію. Наявна реакційна рівняння для цієї реакції - 1:1.

4,6 г станолу (C18H36) маємо молярну масу:

4,6 г / 284 г/моль = 0,016197 моль станолу

За стехіометрією реакції, 0,016197 моль станолу буде взаємодіяти з 0,016197 моль гідроген броміду (HBr). Молярна маса гідроген броміду - 80,91 г/моль.

Тому, маса гідроген броміду (HBr), що утвориться, буде:

0,016197 моль * 80,91 г/моль = 1,31 г

Таким чином, при взаємодії станолу масою 4,6 г з гідроген бромідом утвориться маса 1,31 г гідроген броміду.

Poverty

There is no objective and unique definition of poverty, which is capable to

describe exactly when somebody is poor. There has been an evolution in the

description of poverty. In these definitions, it is shown that poverty is not only lack of

money to buy food, but is also related to living conditions, well-being, health, and

possibilities to change the personal situation. Poverty can be defined in different

ways. Every definition leads to different outcomes, to a different group of people,

which can be considered as poor and, in relation to this, to different policy measures

and a different amount of costs needed to solve the problem of poverty.

Poverty exists for many centuries, but the content of the notion differs from

country to country and from time to time. There is a difference in poverty in Western

Europe and Eastern Europe. There is also a difference in the meaning of poverty in

Western Europe in the last century and today. Last century poverty mostly meant that

a part of the population had to struggle for life and did not have enough money to buy

food: poverty was an absolute notion. Nowadays most of the Western European

countries have comprehensive social security schemes, which cover the whole

population. Almost everybody has a basic income and in some countries this income

is rather high. In those countries therefore poverty cannot longer be seen as a threat of

daily life. There, poverty means that a part of population has arrears in relation to the

average population: poverty is a relative notion.

Most discussions distinguish between absolute or primary poverty and relative

or secondary poverty. “Absolute poverty” refers to a lack of the basic requirements to

sustain physical life. “Relative poverty” is used to demonstrate the inadequacy of

definitions of absolute or primary poverty by referring to the cultural needs of

individuals and families within the context of the rest of society. An absolute poverty

line is a kind of fixed amount. An absolute poverty line is not meant to change with

the standard of living in society. People are defined as “poor” if their income is below

the line and when some absolute needs are not sufficiently satisfied.
