Answer: How many grams are in 2.5 moles of N2?
Explanation: 1 mole is equal to 1 moles N2, or 28.0134 grams.
One mole of N2 molecules would have a mass of 2 X 14.01 g = 28.02 g.
Answer:
- Acetic acid (CH₃COOH) and hydronium ion (H₃O⁺)
Explanation:
Hello,
In this case, based on the acid-base theory which states that acids are known as H⁺ donors, if we consider the direct reaction:
It is clear that the acetic acid is the first H⁺ donor as it losses one H⁺ to turn into the acetate ion. Moreover, if we consider the inverse reaction:
It is also clear that the hydronium ion is the second H⁺ donor as it losses one H⁺ to turn into water.
Best regards.
Answer:
The pressure of O₂ is 0.8 atm.
Explanation:
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
PT = PA + PB
This relationship is due to the assumption that there are no attractive forces between the gases.
In this case:
PT=Pnitrogen + Pcarbon dioxide + Pother gases
Being:
- Pnitrogen: 593.4 mmHg
- Pcarbon dioxide: 3 mmHg
- Pother gases: 7.1 mmHg
and replacing:
PT= 593.4 mmHg + 3 mmHg + 7.1 mmHg
you get:
PT= 603.5 mmHg
Being 760 mmHg= 1 atm, you get:
PT= 603.5 mmHg= 0.8 atm
<u><em>The pressure of O₂ is 0.8 atm.</em></u>
Answer:
Cobaltous Nitride,I think so anyway.......
Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.
Hope it Helps! T^T
