Наименее прочная связь в иодоводороде В ряду: HF-HCl-HBr-HI прочность химической связи падает, потому что атомные радиусы галогенов в данном ряду увеличивается, вследствие длина связи увеличивается и энергия связи уменьшается.

Scotland is the northern part of Great Britain.
Edinburgh is the capital of Scotland. There are two largest cities here: Glasgow and Aberdeen.
Glasgow is the industrial capital of Scotland. It is
the third largest city in Great
Britain. The typical products of Scotland
are timber, whisky and salmon.
Scotland has
three main land regions. They are the Highlands, the Central
Lowlands and the Southern Uplands.
Scotland is
full of mountains and lakes. The highest mountain is Ben
Nevis. There are a lot of rivers there. The river Clyde is Scotland's
most important river. Ships from the Atlantic Ocean can sail up the Clyde to Glasgow. The Clyde was narrow and shallow until the 1700's
when engineers widened and deepened the river to make it navigable. Scotland's longest rivers flow eastward into
the North Sea. Many of Scotland's
rivers flow into wide bays called firths.
Scotland has hundreds of
islands. A large group of islands called the Hebrides lie off the western coast
of Scotland's
mainland.
Population of
Scotland is about 5 million people. The highest density of
population is in the Central Lowlands, where nearly three-quarters of the Scots
live, and the lowest is in the Highlands.
There are two
languages spoken. English is generally spoken and fewer than 100,000
Scots, who are mainly inhabitants of the Highlands
and island groups, also speak the Scottish form of Gaelic.
Scotland is an integral part of Great Britain.
It is represented by 72 members in the
House of Commons and by 16 Scottish peers in
the House of Lords.
Scottish
affairs are administered by a British cabinet ministry, headed by the secretary
of state for Scotland.-
