The chemical makeup of a piece of corn can be determined by conducting chemical analysis techniques such as chromatography, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy. These techniques help identify the specific molecules present in the corn, such as carbohydrates, proteins, lipids, vitamins, and minerals. Additionally, elemental analysis can provide information on the elemental composition of the corn.
Physical changes involve a change in the appearance or state of a substance without altering its chemical composition, such as melting or freezing. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances with different chemical properties, such as rusting or burning.

The candle burning is a chemical process.
Put it on a balance and determine its mass.
Saliva breaking down a piece of bread is a chemical change because enzymes in the saliva break down the starches in the bread into simpler sugars through a chemical reaction. This results in a change in the composition and structure of the bread at a molecular level.
The first piece of information you need to determine elevation is the reference point or datum. This serves as the starting point for measuring height above or below a specific level, such as sea level or ground level.
To determine the molecular formula of a compound, one must know its molar mass. This information, coupled with the molecular weight of its individual elements, allows for the calculation of the ratio of atoms present in the compound, and subsequently leading to the determination of its molecular formula.
A car rusting is considered a chemical change because the iron in the metal reacts with oxygen in the air to form iron oxide, which is a new substance with different properties than the original metal. This process is irreversible and involves the rearrangement of atoms at a molecular level.
The Caruso 97956 14-Piece Protraveler Molecular Steam Hairsetter works on a Molecular structure to set your hair.
Absolutely not. Monosaccharides exist on the molecular level - molecules like glucose, fructose, and galactose. Ham is a piece of meat. The distinction is pretty clear.

Yes, as it's still glass. There is no chemical/molecular change.

The change from solid gold to liquid gold is a physical change because it does not alter the chemical composition of the gold. The transition from solid to liquid is a result of a change in temperature and does not involve any chemical reactions.

Factors that usually determine how strongly a nation will pursue a claim to a piece of land include historical ties, economic resources present in the land, strategic importance of the location, international law considerations, and the level of support from domestic population and political elites.
