Explain the difference between chemical properties and physical properties?
physical property happens by itself or from things in nature. chemical property happens by outside.
Do an elements properties change when it combines with another element?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has in it atoms from the elements used in the formation. The atoms in the molecule are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed. It is the electronic properties of atoms and molecules that really determine the properties they have and which chemical reactions occur and which do not. The chemical properties of an atom or molecule are determined by the arrangement of the electrons of that atom or molecule. Once atoms have gone through a chemical reaction, the electronic structure is changed. The atoms are the same identity, but the properties of the atoms have been changed by the chemical reaction.
What is the difference between a chemical and a physical property of a substance?
A physical property can be observed without changing the material's composition. A chemical property can only be observed when a chemical change takes place.
Does breaking a mirror cause a change of chemical properties?
Breaking a mirror does not cause a change in the chemical properties of the mirror itself. The act of breaking the mirror may result in physical changes, such as the mirror's fragments having sharp edges, but the chemical composition of the mirror remains the same. Mirrors are typically made of a layer of reflective material, like silver or aluminum, which is deposited on the glass surface, and breaking the mirror does not alter this composition.
Partial molar property and its applications?
Partial molar properties are useful thermodynamic properties because their molar average equals the property itself. In this article, we present a description of partial properties in general, and we show that for many partial properties, partial molar properties being a subset, the property is a molar average of the partial properties. Although partial molar properties remain the most useful, several of the other partial properties could have practical applications. © 2009 American Institute of Chemical Engineers AIChE J, 2009

What is the pharmacological attachment theory?
The theory that a drug attaches itself to specialized cells in the body because of its size, shape, electrical charge, and chemical properties is called the
What is the smallest unit of matter that exists by itself and keeps all of the chemical properties of a substance?
Molecules
What is the difference between the chemical and physical properties for sodium chloride?
For all materials physical properties are related to some characteristics as density, hardness, refractive index etc. and the chemical properties are related to some characteristics as chemical reactivity, flammability, oxydation etc. Physical properties are characterized by getting back the original material by changing its form, state, etc. Chemical properties are characterized by a complete change in the material itself i.e. you cannot get back the same material.
What is the smallest unit of matter that can exist by itself and retain all of a substance's chemical properties?
This smallest unit of matter is the atom.
Matter that has the same chemical composition throughout itself is called?
donkeys.
Why salty food causes retention of water and swelling of tissues?
It's one of the chemical properties of salt that it draws moisture to itself.
A substance which helps make a chemical change happen but is not changed itself in the process is called an?
The answer is catalyst
Is the water in you a chemical or physical property?
The water, itself, is not a property. It is a compound. Properties of water are things like boiling point, freezing point, density, color, etc.
What is the different between physical and chemical propties?
Physical properties are properties that can be observed without a chemical reaction. Examples are melting and boiling point, or in some cases sublimation point (conversion straight from a solid to a gas), magnetism, density, luster (shiny), hardness, and color. you can observe if these properties are applicable to a substance without changing it to another substance in the process. When you test for magnetism of a metal, once you find out if it is magnetic or not, you still have the same metal, not something else. Chemical properties require a chemical reaction to take place for the properties to be observed, resulting in the substance changing into an other substance in the process. Two examples are flammability and reactivity with water. When something catches fire and the fire has burned itself out, you no longer have whatever you started off with, such as wood, but rather a pile of ash, which is mostly carbon. When something reacts with water, after it's done reacting, it is no longer what it was to begin with, otherwise it would keep reacting. To find out if chemical properties apply to a compound, you won't still have that compound if the answer is "yes".
