Asample of oxygen gas in one container has a volume of 20.0mililiter at 297 k and 101.3 kpa. the entire sample is transferred to another container where the temperature is 283 k and the pressure is 94.6 kpa. which is correct numerical setup for calculating the new volume of this sample of oxygen gas
show work

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,:

where,

= initial pressure of gas = 101.3 kPa

= final pressure of gas = 94.6 kPa

= initial volume of gas = 20.0 ml

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get the final volume of gas.

Thus the correct numerical setup for calculating the new volume is

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

the answer is d.) potassium
