A chemical reaction alters molecular composition.
Peeling an apple is a physical change. This process alters the apple's outer appearance by removing its skin, but it does not change the apple's chemical composition or its internal structure. The fruit remains the same in terms of its flavor, nutrients, and overall identity.
Yes, if you have some additional information, such as the molecular weight. For instance, the molecules C2H4 and C4H8 have exactly the same percent composition, but they are very different molecules. So you need some other information to tell them apart than the percent composition.Answer ExpandedThis is kind of a trick question. By knowing the percent composition, you would easily be able to determine its empirical formula, but molecular formula is a bit different. The molecular formula is the actual number of atoms in a molecule, so in order to find the specific molecular formula of a substance, you would also need to know how many grams there is of that substance.(This explains the difference between C2H4 and C4H8)

No, a physical change does not change an object into a different kind of matter. It only alters the form or appearance of the substance, such as size, shape, or state (solid, liquid, gas), without changing its chemical composition.

Chemical weathering changes the composition of a rock by breaking down minerals through chemical reactions with water, oxygen, acids, or other substances. This process can alter the rock's mineral composition, leading to the formation of new minerals or the dissolution of certain minerals.
CH3COOH, or acetic acid, is a covalent molecular solid at room temperature.
