Why do physical properties play a role in chemistry if they do not involve any chemical changes?

Because the shape of a molecule can affect how other things can react with it. Every chemical has a shape, eg CO2 forms a straight line O=C=O, however some are different shapes to others, resulting in different possible reaction routes (ie water, H2O, where the H-O bonds are pushed together resulting in an angle of 104.5o between them).
Also, there are many (notably larger) compounds which have the same chemical formula, but different structures, ie Cys, Trans isomers. If one performs a reaction on one, it will yield a vastly different product to the same reaction performed on the other isomer.
Physical properties affect how chemicals "stack up" (affecting the freezing and boiling points), which path they take in reactions and their colour, as well as numerous other factors.

Does a chemical reaction change physical properties or chemical?
it changes chemical properties
Changes in properties of matter are called?
physical or chemical changes
Do chemical changes affect the chemical structure of a substance?
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
What happens in chemistry?
Chemistry is the study of matter, its properties, and its interactions. It explores topics such as chemical bonding between elements (ionic and molecular), classification of the periodic table, electron configuration, physical and chemical properties of matter, and the like.

What is a characteristic of a chemical equilibrium but not physical equilibrium?
Chemical equibrium can involve changes in chemical properties.
What is the study of the properties of chemicals and chemical changes?
Chemistry!!
Does a chemical reaction change physical properties or chemical?
it changes chemical properties
What are physical and chemical?
physical changes do not change the chemical properties of a substance
What are property changes?
the properties that change are physical and chemical properties!!! :)
Changes in properties of matter are called?
physical or chemical changes
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Do chemical changes affect the chemical structure of a substance?
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
Are changes in the state of matter are physical chemical or neither?
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
Are color and density chemical changes?
Color and density are physical properties, not changes.
When elements form bonds it changes what?
chemical & physical properties
