Answer:
See explanation
Explanation:
In chemistry, the idea of "like dissolves like" is of utmost importance. A substance is only soluble in another with which it can effectively interact.
We must note that to be "soluble" means that the solute actually interacts effectively (dissolves) in the solvent.
However, vinegar is a polar substance while oil is a non polar substance hence the two can not effectively interact. That is, the vinegar can not dissolve in oil.
The two will separate into two phases upon standing. Therefore, the bottle of salad dressing made with oil and vinegar must be shaken in order to mix the two thoroughly before it is used.
A model aids in visualizing a molecule and understanding its properties.
In chemistry, models of molecules give us an idea about the arrangement of atoms in the molecules. Usually, the arrangement of atoms in a molecules determines the kind of reactions that the molecule can undergo.
Models are three dimensional representations of what molecules look like. They help us to conceptualize the possible orientation of atoms and groups in the molecule.
Looking at the model of H2SO4, it becomes easier to understand the chemical and physical properties of the compound owing to the arrangement of atoms.

Your attempted answer is correct.
Indeed, certain liquids, including water, could superheat when heated in a perfectly smooth container. The superheating could be interrupted by the minutest speck of dust or impurities causing a mass conversion into steam, observed physically as a bumping, causing splashes and endangering operators. Boiling chips introduce these interruptions constantly and ensure a smooth boiling of the liquid.
For every action there is an opposite and equal reaction. Your foot pushes on the boat and the boat pushes against the water which doesn't have much friction, so the boat moves backward instead of you moving forward. On land, the land pushes back up at you with the same force so you move forward.
