When a compound melts, the intermolecular forces holding the molecules together weaken, allowing the molecules to move past each other and flow freely. The molecules do not break apart or undergo any chemical changes during melting.

Are compounds solutions?

Not all compounds are solutions. Solutions are specific types of mixtures where substances are evenly distributed on a molecular level, while compounds are substances made up of two or more different elements chemically bonded together. A compound can be in a solution if it is dissolved in a solvent.


Can an element be part of a heterogeneous mixture?

Yes, an element can be part of a heterogeneous mixture. For example, if iron filings are mixed with sand, the resulting mixture would be heterogeneous as the iron filings and sand do not mix at a molecular level.


How is the greenhouse effect caused on a molecular level?

The greenhouse effect occurs when certain gases in Earth's atmosphere, such as carbon dioxide and methane, trap heat from the sun. These gases absorb infrared radiation emitted by Earth's surface, preventing some of the heat from escaping into space. This results in a warming effect on the planet.


Are compounds impure?

Yes, compounds can be impure if they contain other substances or impurities alongside the desired compound. Impurities can affect the compound's properties and purity level. Purification methods, such as filtration or distillation, can help remove impurities from compounds.


What did John hartes data show about the pH of the pond after the snow melted?

Dr. John Harte hypothesized that melting snow causes acidity in the ponds he was studying. His data indicated that there was a drop in the pH level of the ponds after the snow melted, which proved his hypothesis.

Is sand a molecular compound?

sand is a heterogeneous mixture of different grains of different types of stone. An ionic bond is a bond that happens at a molecular level (atoms bonding with atoms), and sand is just many small rocs and crystals mixed together


Is it correct that 1500 pounds of ice would weigh about 12000 pounds of water if melted?

No, it is not true. 1500 lbs of ice, if melted with no evaporation occurring, would equal 1500 lbs of water. When you freeze a liquid, nothing is added or subtracted at a molecular level. Therefore, no weight change could occur.


How does molecular bonding differ from nuclear fusion?

Molecular bonding involves the sharing or transfer of electrons between atoms to form molecules, creating chemical compounds. Nuclear fusion is a process in which atomic nuclei combine to form a heavier nucleus, releasing large amounts of energy in the process. While molecular bonding occurs at the atomic level, nuclear fusion involves the fusion of atomic nuclei at the nuclear level.

Is a birds nest a compound?

No, a birds nest is a structure. Each of its componenet parts maintains its separate ideneity. A compound is the result of elements or compounds uniinge at an atomic or molecular level to make a new material.
