No, the chemical composition of a molecule remains the same when it changes states of matter. Changes in state involve the arrangement and movement of molecules, but the actual chemical makeup of the molecules remains unchanged.
A change in temperature or pressure can affect the state of matter without altering its chemical composition. For example, melting ice to form liquid water or boiling liquid water to form steam are changes in state of matter that do not change the chemical makeup of water molecules.
When ice melts, the chemical composition remains the same. Ice is just the solid state of water, so when it melts, it turns into liquid water. The molecules in ice rearrange themselves into a more disordered state to become liquid water, but the chemical makeup of the water molecules themselves does not change.
a chemical formula
Zinc is only a metallic chemical element.
Without carbon they are organic molecules. An example of one is water, having a chemical makeup of two hydrogen and one oxygen molecules. (h2o)

Matter with a definite chemical makeup is a pure substance.
No, shortening melting is a physical property. Chemical properties involve changes in the chemical makeup of a substance, while physical properties describe characteristics that can be observed without changing the substance's chemical composition.

a spectroscope is the instrument used to determine the chemical makeup of a star.

The chemical formula is N34K4Na9
Modern scientists describe the makeup of matter in terms of particles such as quarks, leptons, and bosons. These particles combine to form atoms, which in turn form molecules. The Standard Model of particle physics is the current framework used to describe the fundamental particles and forces that make up the universe.
During a physical change, the chemical makeup of matter remains the same. The atoms and molecules that make up the substance do not change their identities, only their arrangement or state. This means that no new substances are formed during a physical change.
Soap will do it.
