What is the difference between phyical and chemical changes?
A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
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.
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.
Why is a car rusting a physical change?
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
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.

chemical
Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
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.
How can one effectively interpret a mass spectrum to identify the molecular structure of a compound?
To effectively interpret a mass spectrum and identify the molecular structure of a compound, one must analyze the peaks in the spectrum to determine the mass-to-charge ratio of the compound's fragments. By comparing these ratios to known values for different molecular fragments, one can piece together the structure of the compound. Additionally, isotopic patterns and fragmentation patterns can provide further clues to confirm the molecular structure.
