Aluminum was first isolated in 1825 by Hans Christian Ørsted (Oersted) in Copenhagen, Denmark who reported, “a lump of metal which in color and luster somewhat resembles tin.” Ørsted produced aluminum by reducing aluminum chloride using a potassium-mercury amalgam. The mercury was removed by heating to leave aluminum.

Extraction of aluminium Aluminium ore is called bauxite . The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted. The extraction is done by electrolysis.

bauxite

Aluminium ore is called bauxite (Al 2O 3). The bauxite is purified to yield a white powder – aluminium oxide (also known as alumina) – from which aluminium can be extracted. The extraction is done by electrolysis , but first the aluminium oxide must be melted so that electricity can pass through it.

This is because it is goes by both aluminum and aluminium. The modern distinction between these two terms is clear: aluminum is correct in American English, as well as Canadian English, while aluminium is correct in British English, as well as most other forms of English.

In most English-speaking countries, including Australia, Canada, India, Ireland, New Zealand and the United Kingdom, the letter’s name is zed /zɛd/, reflecting its derivation from the Greek zeta (this dates to Latin, which borrowed X, Y, and Z from Greek, along with their names), but in American English its name is zee …

Canadians do something called ‘Canadian Raising’, meaning that they pronounce some two-part vowels (known as dipthongs) with a higher part of their mouths than people from other English-speaking regions – this is what causes the ‘ou’ sounds in words like ‘out’ and ‘about’ to be pronounced something like ‘oot’ and ‘ …

His English accent was inspired by Kahn’s study of Washington in preparation for the role. On the choice to do the accent, Kahn said he took his inspiration from the assumption that the General would have sounded a bit like an English officer because, as a young man, Washington was frequently around English officers.

The United States declared its independence from Great Britain in 1776. The American Revolutionary War ended in 1783, with Great Britain recognizing U.S. independence. The two countries established diplomatic relations in 1785.

By 1775 relations between Britain and the colonies had deteriorated badly, and a war broke out between them. This eventually became known as the War of the American Revolution or the American War of Independence . The war ended after Lord Cornwallis’ surrendered at Yorktown in 1781. …

British America comprised the colonial territories of the British Empire in America from 1607 to 1783.

WEINTRAUB: Britain lost the war because General Washington had two other generals on his side. One was `General Demography,’ population. The population was burgeoning. And the other general that Washington had on his side was `General Atlantic,’ that is Atlantic Ocean.

After French assistance helped the Continental Army force the British surrender at Yorktown, Virginia, in 1781, the Americans had effectively won their independence, though fighting would not formally end until 1783.

The American Revolution was principally caused by colonial opposition to British attempts to impose greater control over the colonies and to make them repay the crown for its defense of them during the French and Indian War (1754–63). Learn about the Boston Tea Party, the colonists’ radical response to a tax on tea.

During the Revolution, the French Government also provided the Americans with loans, eventually totaling over two million dollars, most of which were negotiated by Benjamin Franklin. John Adams also secured a loan from Dutch bankers in 1782.

In the American Revolution, gaining freedom was the strongest motive for Black enslaved people who joined the Patriot or British armies. It is estimated that 20,000 African Americans joined the British cause, which promised freedom to enslaved people, as Black Loyalists.

In 1780, Pennsylvania became the first state to abolish slavery when it adopted a statute that provided for the freedom of every slave born after its enactment (once that individual reached the age of majority).

The “railroad” is thought to have helped as many as 70,000 individuals (though estimations vary from 40,000 to 100,000) escape from slavery in the years between 1800 and 1865. Even with help, the journey was grueling.

The British regularly returned slaves who fled from Loyalist masters. Dunmore’s Proclamation inspired thousands of slaves to risk their lives in search of freedom. They swam, dog-paddled and rowed to Dunmore’s floating government-in-exile on Chesapeake Bay in order to find protection with the British forces.
