The answer is cC. Because it contain only one atom
The final pressure of the gas in the container is 4 atm
From the question given above, the following data were obtained:
Initial volume (V₁) = 4 L
Initial temperature (T₁) = 300 K
Initial pressure (P₁) = 1 atm
Final temperature (T₂) = 600 K
Final volume (V₂) = 2 L
<h3>Final pressure (P₂) =?</h3>
- Using the combine gas equation, we can obtain the final pressure of the gas as illustrated below:

Cross multiply
300 × 2 × P₂ = 4 × 600
600 × P₂ = 2400
Divide both side by 600

<h3>P₂ = 4 atm</h3>
Therefore, the final pressure of gas is 4 atm.

Answer:
1,100 km/h
Explanation:
Velocity = distance/time = 4,400 km / 4.0 h = 1,100 km/h
If you’re referring to H vs H2,
H is usually found in ion form as H+
H2 is the designation for pure hydrogen gas, as it is diatomic and can only exist on its own in nature if it’s bonded to another H atom.
In this case, H is an ion and H2 is hydrogen gas
The way you wrote them out, though, indicates that they could be something different. Maybe isotopes? In this case the 1 and 2 are indicative of the amount of neutrons that the atom has.
Answer:C. Compounds are the smallest unit of an element that occur on the periodic table!!
