Explanation:
Gases: more space therefore meaning that particles in the gas have the highest Kinetic energy therefore moving faster all around.
Liquid: they have more kinetic energy than liquid,but they have some space for movement so they collide each other quicker due to lack of space.
solids: They have least kinetic energy as they have no space at all meaning particles can move around and only just vibrate against each other.
The option that would be appropriate to model nuclear fission is disturbing a drop of water such that it breaks into smaller droplets
Nuclear fission refers to the splitting of a heavy nucleus into lighter nuclei owing to the bombardment of small particle.
The liquid drop model provides the most apt model for describing the concept of nuclear fission. In nuclear fission, the nucleus breaks due to the increase in repulsion between the nuclear charges.
As the size of the nucleus continues to increase, any little disruption will; result in the breaking up of the nucleus into smaller fragment called daughter nuclei.
Hence, the model of disturbing a drop of water such that it breaks into smaller droplets is the most apt description of nuclear fission.

Answer:
B : 0.133 M
Explanation:
moles Li3N3 = 0.4 mol Li x (2 moles Li3N/6 moles Li) = 0.133 M
Answer:
1.041g is the maximum sigle dose for the person
Explanation:
The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults
To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):
153lb * (0.4536kg / 1lb) =<em> 69.4kg is the mass of the person</em>
<em />
As the maximum dose is 15.0mg / kg, the dose of the person is:
69.4kg * (15.0mg acetaminophen / kg) =
<h3>1041mg = 1.041g is the maximum sigle dose for the person</h3>
A student compares the boiling point of substances having different intermolecular forces. <u>Boiling points of various substances</u> is the dependent variable that student most likely use.
<h3>Does the nature of intermolecular forces present in different substance affect their boiling points?</h3>
The boiling point of a substance is proportional to the strength of its intermolecular forces, the higher the boiling point, the stronger the intermolecular forces. We can compare the strengths of intermolecular forces by comparing the boiling points of different substances.
<h3>What properties are affected by intermolecular forces?</h3>
Intermolecular forces are measured by boiling points.
Intermolecular forces increase as bond polarization increases.
Ionic > hydrogen bonding > dipole dipole > dispersion is the order of the strength of intermolecular forces (and thus their impact on boiling points).
<h3>How can you determine strong and weak intermolecular forces?</h3>
Substances with strong intermolecular forces are very attracted to one another and are held together tightly. These substances require a great deal of energy to separate, whereas substances with weak intermolecular forces are held together very loosely and have weak interactions.
