What does not change when a substance changes matter?
During a physical change, the matter of what the substance is made out of doesn't change.
What type of property cannot be observed without changing composition of a substance?
a physical property a chemical property; physical properties are properties such as freezing/melting/boiling points
What is the most important question to ask to determine whether a change is physical or chemical?
did the composition change
Which type of property cannot be observed without changing the composition of a substance?
Chemical properties cannot be observed without changing its composition. ie: oxidation numbers Physical properties are properties such as melting point and boiling point. All that is needed to observe these are by placing the compound in a melting point apparatus etc.
How are physical and chemical properties of matter useful?
Physical and chemical properties of matter are useful because they can help you identify that substance. For example paper burns very easily and aluminum doesn't, this is how they can be described individually.
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 does not change when a substance changes matter?
During a physical change, the matter of what the substance is made out of doesn't change.
How do chemical and physical properties differ?
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
Is something that reacts with acid a chemical or physical property?
If something reacts with acid it is a chemical property.
What type of property cannot be observed without changing composition of a substance?
a physical property a chemical property; physical properties are properties such as freezing/melting/boiling points
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
What is the different between the physical and chemical properties 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.
Which property of a substance does not change when the amount of the substance changes?
All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.
What are physical and chemical?
physical changes do not change the chemical properties of a substance
Can the chemical properties of a substance be observed without changing the substance?
physical properties
What are the differences between a chemical and physical change?
A physical change doesn't change the molecular properties of a substance. Some examples of physical changes include tearing paper, or the evaporation of water. A chemical change does change the molecular properties of a substance. For example, if you burn wood you get leftover carbon, and CO2 is also released; no longer does the wood have the same molecular properties or structure.
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!!!
