A 4.0L weather balloon is launched from sea level where the temperature is 25°C. It rises to an altitude where the pressure is 0.05atm and the temperature is -75°C. If the balloon has the capacity to expand to a 50 liter volume before bursting, will the balloon survive?
Answers
Answer: The balloon will not survive.
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 = 1 atm
= final pressure of gas = 0.05 atm
= initial volume of gas = 4.0 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
As the balloon has the capacity to expand to a 50 liter volume before bursting, it can not survive as it occupies volume higher than 50 L

Explanation:
Hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule can be termed as an intramolecular bond.
Generally, the oxygen atom is partially negatively charged, and the hydrogen atom is partially positively charged, so an arttraction occurs which forms this hydrogen bond. The attraction of the O-H bonding electrons towards the oxygen atom leaves a deficiency on the far side of the hydrogen atom relative to the oxygen atom. The result is that the attractive force between the O-H hydrogen and the O-atom of a nearby water molecule is strong.

Answer:
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
Explanation:
Answer:
Yes
Explanation:
The higher the electronegativity the higher tendency to attract electrons, the lower the electronegativity the higher tendency to give away electrons/lose electrons.
