Doubling the mass doubles the energy, while doubling the velocity quadruples it. Your question is basically about order of operations; the exponent only applies to the variable it's immediately on. As you note, you'd have to put parentheses to make it cover the
m as well. We say that energy is linear in mass, but quadratic in velocity.
Answer: if you have this app then you’r not smart
Explanation: because cheating is not allowed
Answer: The final pressure is 116kPa or
Explanation:
The combined gas equation is,
where,
= initial pressure of gas =
= final pressure of gas = ?
= initial volume of gas = v ml
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The final pressure is 116kPa or
You lied that was 12 points, but answer is nitrogen....bcuz Ionization energy is the minimum energy needed to remove a mole of electrons from a mole of gaseous atoms.
O has a lower 1st IE than N because O is 1s2 2s2 2p4 and N is 1s2 2s2 2p3. The 4th electron in the O atom's outer level has to pair up with one of the others, and this introduces repulsions, which makes it easier to remove.
The relevant factors are nuclear charge, atomic radius and screening by inner electrons.
Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include freezing point depression, boiling point elevation, vapor pressure lowering, and osmotic pressure.
Hope this helps
