Carbon dioxide is commonly found as a solid (dry ice) or a gas (carbon dioxide gas). Jeff's teacher asked him to draw models to
show the motion of carbon dioxide molecules that make dry ice different from carbon dioxide gas. Describe what was correct and what might be improved about Jeff's models in showing the motion of the carbon dioxide molecules that make dry ice different from carbon dioxide gas

Answer:
An image is given for reference.
Explanation:
- Dry ice is also named as CO 2 and gets its name as it does not melt into a liquid when heated, and instead, it directly changes into a gas by the process of sublimation.
- When energy is being transferred from one state to another the CO 2 gas is pressurized and refrigerated. In terms of molecular motion and kinetic energy, gas molecules can exert pressure and molecules moves in up and down direction.

Hello!
In this case, since the net ionic equation of a chemical reaction shows up the ionic species that result from the simplification of the spectator ions, which are those at both reactants and products sides, we take into account that aqueous species ionize into ions whereas liquid, solid and gas species remain unionized. In such a way, for the reaction of cesium phosphate and silver nitrate we can write the complete molecular equation:
Whereas the three aqueous salts are ionized in order to write the following complete ionic equation:
In such a way, since the cesium and nitrate ions are the spectator ions because of the aforementioned, the net ionic equation turns out:
