How do you determine the chemical make up on the molecular level of a piece of corn?
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.

What is the difference between phyical and chemical changes?
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.
Is corrosion of a piece of metal chemical or physical change?
chemical change
tearing a piece of paper in half physical or chemical change?
Physical change
A different chemical substance is formed when a piece of cloth is cut cup breaks candle burns or a piece of chalk breaks?
The candle burning is a chemical process.
How can demonstrate that a piece of chalk mass has mass?
Put it on a balance and determine its mass.
Is saliva breaking down a piece of bread a chimacal change?
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.
What is the first piece of information you must have when trying to determine an elevation?
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.
What critical piece of information must be known in order to determine the molecular formula?
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.
Why is a car rusting a physical change?
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.
What's the Molecular all about with these rollers on theCaruso 97956 14-Piece Protraveler Molecular Steam Hairsetter?
The Caruso 97956 14-Piece Protraveler Molecular Steam Hairsetter works on a Molecular structure to set your hair.
Is ham a polysaccharide?
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.
What is the difference between phyical and chemical changes?
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.
Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
Is corrosion of a piece of metal chemical or physical?
chemical
A piece of solid gold that changes from a solid to a liquid is a physical or chemical 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.
Is corrosion of a piece of metal chemical or physical change?
chemical change
What factors usually determine how strongly a nation will pursue a claim to a piece of land?
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.
