In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
What is the chemical equation for hydrogen fluorine?
An explosive reaction:Hydrogen + Fluorine ----> Hydrogen FluorideH2 + F2 ----> 2 HF
Is oxidizing a chemical or physical property?
It is a chemical because it is producing a new substance.
Is fluorine an atom?
Fluorine is an element, not an atom. An atom is the smallest unit of an element that retains its chemical properties, while an element is a substance made up of only one type of atom. Fluorine is a chemical element with the symbol F and atomic number 9.
Is freezing point physical property a physical change a chemical property or a chemical change?
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
Is State chemical or physical?
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different 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 are physical and chemical?
physical changes do not change the chemical properties of a substance
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
Is the color of a substance a physical substance?
Mostly, it's a chemical substance.
Is boiling point a chemical property in a substance?
Boiling point is a physical property not a chemical property.
What is the chemical equation for hydrogen fluorine?
An explosive reaction:Hydrogen + Fluorine ----> Hydrogen FluorideH2 + F2 ----> 2 HF
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
What is the diffence between a physical and chemical change?
Physical change doesn't produce a new substance, but a chemical change is a new substance.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
Is oxidizing a chemical or physical property?
It is a chemical because it is producing a new substance.
