Answer:
The partial pressure of helium gas in a gaseous mixture of helium and hydrogen is the pressure that the helium would exert in the absence of the hydrogen. equal to the total pressure divided by helium's molar mass. O equal to the total pressure divided by the number of helium atoms present.

The unit 'kJ' or kilojoules is a unit of measurement for energy. It is equivalent to the SI units kg·m²/s². When energy is divided with time, that unit is now in terms of work, which energy per unit time. The parameter kJ/s is equivalent to kW or kilowatts.
Work = 35,000 kJ/0.250 s = <em>140,000 kW</em>
Answer:
The answer is B
Explanation:
Less air means less air pressure. At a certain point, there is very little air pressure to push against the outward pressure of the helium inside the balloon. It will then expand until the rubber breaks, and the balloon bursts
