What else can I help you with?
What type of intermolecular forces would you expect to find in a pure liquid sample of carbon tetrachloride?
In a pure liquid sample of carbon tetrachloride (CCl4), you would expect to find London dispersion forces. Carbon tetrachloride is a nonpolar molecule, so it does not have dipole-dipole or hydrogen bonding interactions.
What can you conclude about two liquid samples that have boiling points?
The liquid sample with the higher boiling point likely has stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, compared to the liquid sample with the lower boiling point. Boiling point is a reflection of the strength of intermolecular forces in a substance.
How does the melting behavior of lauric acid would change if an impurity was introduced in the sample?
The presence of an impurity in lauric acid would likely decrease the melting point of the sample due to impurity disrupting the crystal lattice structure, making it easier for the molecules to overcome the intermolecular forces and transition from solid to liquid. The impurity can act as a defect, which requires less energy to break the bonds holding the crystal structure together, resulting in a lower melting point.
Compared to the particles in a hardened lava sample the particles in a liquid lava sample?
The particles in a hardened lava sample will be solidified and compacted, while the particles in a liquid lava sample will be molten and in a flowing state. The hardened lava particles will have a crystalline structure, whereas the liquid lava particles will lack a fixed arrangement due to their high temperature.
What happens to the molecules that make up a sample of liquid water when the sample absorbs enough heat to reach the boiling point?
Those with the most kinetic energy have enough to thrash about so much that they push their neighbours away and make a hole in the liquid water we call a bubble. Other energetic molecules then burst into the hole and help to keep it from collapsing. If enough molecules burst in, the bubble is so big that it rises to the surface and bursts, releasing a cloud of steam into the air. The molecules most likely to be able to initiate this formation of bubbles are those at the very bottom of a saucepan where they are touching the hot metal with the fire underneath it. That is why the first bubbles which boil off come from the bottom of the can.

Which type of energy would exist in a liquid sample but not in a gas sample of the same molecular compound?
You think probable to intermolecular forces.

What would be the most significant type of intermolecular forces in a liquid sample of fluoroform?
The most significant type of intermolecular forces in a liquid sample of fluoroform (CHF3) would be dipole-dipole interactions due to the presence of polar C-F bonds. Fluoroform is a polar molecule with a net dipole moment, so the positive end of one molecule will be attracted to the negative end of another molecule, leading to dipole-dipole interactions.
The temperature of a sample of an unknown gas goes from 100 K to 5 K and the volume and number of moles remains constant would you expect the sample of gas to behave more or less ideally and explain?
Generally, the lower the temperature, the less ideally a gas behaves. The main reason for this is that in an ideal gas, intermolecular forces are ignored. The slower the molecules go, the bigger the influence of intermolecular forces, the less ideal the gas.
What is the most important type of intermolecular forces between molecules in a sample of pure water?
Hydrogen bonding
What is the chief factor that determines the physical state of a sample of matter?
The chief factor that determines the physical state of a sample of matter is the intermolecular forces present between its particles. These forces determine how closely the particles are packed together and how they move, leading to the distinctive properties of solids, liquids, and gases.
How do you decide whether a sample of matter is a solid liquid or gas?
The differences between a solid, liquid and gas are simple! A solid is an object that has a set volume, and is hard to compress. A liquid will take the shape of its container, but is hard to compress. A gas will take the shape of its container, and is easy to compress.
Which 5.0 milliter sample of NH3 will take the same shape of and completely fill a closed 100.0 milliter container?
In a gas intermolecular forces are weakened and the expansion is easily possible.
What forces hold the molecules of a liquid together?
strong
What song did biggie sample for nasty boy?
Contains a sample of "Cavern" by Liquid Liquid
