Answer:
102.26 moles of helium were required to Fill the Goodyear Blimp
Explanation:
To solve this question we need to use combined gas law:
PV = nRT
<em>Where P is pressure, V is volume of gas (2500L), n are moles of gas (Our incognite), R is gas constant (0.082atmL/molK) and T is absolute temperature</em>
<em />
Assuming atmospheric condition we can write P = 1atm and T = 25°C = 298.15K
Replacing:
PV/RT = n
1atm*2500L / 0.082atmL/molK*298.15K = n
<h3>102.26 moles of helium were required to Fill the Goodyear Blimp</h3>

Well... <span> to make life easier by means of machinery or tools. Basically the goal of technology is to advance the human race in ways we never would have been able to from the beginning. That's my definition or goal.</span>
Answer is: P (phosphorus).
Magnesium form cation Mg²⁺, Mg lost 2 electrons, ionic radius decreases.
Aluminium form cation Al³⁺, lost 3 electron, radius decreases.
Phosphorous can form the phosphide anion P³⁻, gain 3 electrons, ionic radius increases.
Sulfur can form anion S²⁻, gain 2 electrons, but have one proton more than phosphorus, so smaller radius.
Answer:
The answer is forensic sociologist
I just took the exam and it’s rights
the answer is D. because a topographic map measures the lowest and highest points in a certain place
Hope this helps
