Answer:
B. The energy absorbed in the first move is greater than the energy released in the second move.
Explanation:
It takes large amounts of energy for a electron to jump energy levels and the further it moves, the more it takes.
Answer:
<h2>145 mL</h2>
Explanation:
The volume of the nugget can be found by using the formula
volume of object = final volume of water - initial volume of water
From the question
final volume of water = 225 mL
initial volume = 80 mL
We have
volume = 225 - 80 = 145 mL
We have the final answer as
<h3>145 mL</h3>
Hope this helps you
Answer:
it breaks down things and cools things down
Explanation:
Answer: The boiling point will be highest for butan-1-amine.
Explanation:
Dipole moment is defined as the separation of positive and negative charges.
More the dipole moment of a compound, more separation between the positive and negative charges and more polar will be the bond.
When a compound has strong dipole-dipole interactions and is heated, more energy will be required to overcome these strong interactions and hence, will have high boiling point. This means that polar molecules have high boiling points than non-polar molecules.
In the given question:
The dipole moment is highest for butan-1-amine which is 3.2 D and will also have highest boiling point among the given molecules.
Hence, the correct answer is butan-1-amine.
The kinetic energy of a gas molecule increases when the sample of gas is heated.
