Because of the relatively high altitude of antonito, colorado, the town has a normal barometric pressure of about 600 mm hg rather than 760 mm hg as at sea level. the partial pressure of o2in antonito’s air is approximately mm hg. a. 75.b. 126.c. 160.d. 76.e. 21.

126 mm Hg

Explanation:

the percentage by volume of oxygen in the air is 21%. Therefore it also contributes to the 21% of the total barometric pressure of the air.

Now, 21% of 600 mm Hg

=21/100*600= 126mm Hg

therefore The partial pressure of O2in Antonito’s air is approximately is 126 mm of Hg.

The correct answer is option b. 126

Explanation:

Hi! Let's solve this!

We have 21% oxygen in the air, the rest is mostly nitrogen (78%) and the remaining 5 are other gases. So:

The partial pressure of oxygen is 21% of 600 mmHg.

That is calculated as follows:

ppO2 = 600 * 21/100 = 126 mmHg

We conclude that the correct answer is option b. 126

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

yes it is weird but true
