Answer: measure the weigh on a type of machine
Explanation:
Water compression increases
P1/T1 = P2/T2
125⁰C = 398.15 k
182⁰C = 455.15 k
1.22/398.15 = p2/455.15
p2= 1.39atm
the pressure of the gas be after the temperature change is 1.39 atm
The number of electrons present in the nonbonding π molecular orbital of the allyl anion is 4 electrons . 2 in the pi bond of the allyl ion and the other two will be present as a lone pair on the carbon atom.
<h3>What is a nonbonding π molecular orbital?</h3>
It is a type of orbital that does not affect the bond order or bond length and the bond order of the molecule and does not affect its energy too.
In allyl anion allyl anion occupies 4 pi electrons and ψ2 is the Highest Occupied Molecular Orbital whereas ψ3* is the Lowest Unoccupied Molecular Orbital
Therefore, the number of electrons present in the nonbonding π molecular orbital of the allyl anion is 4 electrons . 2 in the pi bond of the allyl ion and the other two will be present as a lone pair in on the carbon atom.

Answer:
A. Energy is necessary for bond formation.
C. Breaking bonds takes energy.
D. When bonds are formed, energy is released.
Energy is always required for bond formation because when a chemical reaction occurs, either molecular bonds are broken or other bonds are formed to make different molecules. Energy is released during bond formation and is an exothermic process because bond formation represents a stable configuration and the energy lost is released as heat energy that makes it more stable. Breaking bonds takes energy and is an endothermic reaction because energy is absorbed to break bonds.
Hope that helps. x
