Answer:

umm here are some facts about it!Hope this helps!

The first cylinders for storing oxygen were developed in 1868,5 which allowed its use in general anesthesia. By 1885, George Holtzapple used oxygen to manage a young patient with pneumonia, and established its role in acute care.

"The existence and properties of oxygen had been noted by many scientists before the announcement of its isolation by Priestley in 1774. Scheele had also succeeded in preparing oxygen from a number of substances, but the publication of his findings was delayed until after that of Priestley's. As a result, Priestley and Scheele are credited with the discovery of the element independently. The fact that the gas is a component of the atmosphere was finally and definitely established by Lavoisier a few years later. In 1929, W. F. Giaque and H. L. Johnston announced the discovery of two isotopes of oxygen, of mass numbers 17 and 18.

Oxygen is a colorless, odorless, tasteless gas; it is the first member of Group 16 of the periodic table

. It is denser than air and only slightly soluble in water. A poor conductor of heat and electricity, oxygen supports combustion but does not burn. Normal atmospheric oxygen is a diatomic gas (O2) with a molecular weight of 31.9988. Ozone is a highly reactive triatomic (O3) allotrope of oxygen (see allotropy). When cooled below its boiling point oxygen becomes a pale blue liquid; when cooled still further the liquid solidifies, retaining its color. Oxygen is paramagnetic in its solid, liquid, and gaseous forms. Although eight isotopes of oxygen are known, atmospheric oxygen is a mixture of the three isotopes with mass numbers 16, 17, and 18.

Oxygen is extremely active chemically, forming compounds with almost all of the elements except the inert gases. Oxygen unites directly with a number of other elements to form oxides. It is a constituent of many acids and of hydroxides, carbohydrates, proteins, fats and oils, alcohols, cellulose, and numerous other compounds such as the carbonates, chlorates, nitrates and nitrites, phosphates and phosphites, and sulphates and sulphites."

What are three powers of congress that you think are most important? Why?
adelina 88 [10]
The three powers are : The power to raise armies,to declare war, and write bills to be approved by the president. I find these three most important out of all because these affect our economy and country more then the rest (Not saying the rest aren't important just don't think there as important as the three i listed above)

Write a paragraph discussing how the war in Europe affected the relationship between Congress and the president.
siniylev [52]

Through the many wars and peace congresses of the 18th century, European diplomacy strove to maintain a balance between five great powers: Britain, France, Austria, Russia, and Prussia. At the century’s end, however, the French Revolution, France’s efforts to export it, and the attempts of Napoleon I to conquer Europe first unbalanced and then overthrew the continent’s state system. After Napoleon’s defeat, the Congress of Vienna was convened in 1814–15 to set new boundaries, re-create the balance of power, and guard against future French hegemony. It also dealt with international problems internationally, taking up issues such as rivers, the slave trade, and the rules of diplomacy. The Final Act of Vienna of 1815, as amended at the Congress of Aix-la-Chapelle (Aachen) in 1818, established four classes of heads of diplomatic missions—precedence within each class being determined by the date of presentation of credentials—and a system for signing treaties in French alphabetical order by country name. Thus ended the battles over precedence. Unwritten rules also were established. At Vienna, for example, a distinction was made between great powers and “powers with limited interests.” Only great powers exchanged ambassadors. Until 1893 the United States had no ambassadors; like those of other lesser states, its envoys were only ministers.
