What else can I help you with?
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Why doesn't an atoms identity change during a chemical change?
The energy involved in chemical reactions is not so strong to affect the identity of atoms; only nuclear reactions can modify an atom.
Can elements be joined together in chemical reactions?
No and element cannot be broken down or changed into another substance through a chemical change. The number of protons in the nucleus of an atom determines the identity of the substance. But, a chemical change involves only the atoms electrons. -SmartyPants94
What are the definitions of chemical and physical properties?
Chemical properties describe how a substance interacts with other substances to form new chemical bonds or undergo chemical reactions. Physical properties, on the other hand, describe the characteristics of a substance that can be observed without changing its chemical identity, such as color, density, and melting point.
A material that can be observed or measured without changing the identity of the material is called?
A physical property. This refers to characteristics of a material that can be observed or measured without changing the substance's chemical identity, such as color, density, or melting point.

What chemical and physical properties do compounds have?
Chemical properties of compounds refer to how they interact with other substances in chemical reactions, such as their reactivity, ability to form bonds, and composition of elements. Physical properties include characteristics such as color, density, melting point, boiling point, and solubility, which can be observed without changing the chemical identity of the substance.

What is the deffinition of chemical property?
a property used to characterize materials in reactions that change their identity
Why are the coefficients the only part of the chemical formula that can be changed in a chemical reaction?
Coefficients in a chemical formula represent the ratios of the number of molecules or atoms involved in a reaction. Changing coefficients alters the amount of each substance without changing the identity of the elements involved. The coefficients are adjusted to balance the reaction equation while keeping the overall chemical identities intact.
Flammability physical or chemical?
Burning something is a chemical property. A physical property is an aspect of matter that can be measured without changing it. A chemical property may only be observed by changing the chemical identity of the substance.
What are the definitions of chemical and physical properties?
Chemical properties describe how a substance interacts with other substances to form new chemical bonds or undergo chemical reactions. Physical properties, on the other hand, describe the characteristics of a substance that can be observed without changing its chemical identity, such as color, density, and melting point.
Why is it incorrect to balance a chemical equation by changing the subscripts?
Changing subscripts in a chemical formula changes the identity of the compound being represented. Balancing a chemical equation involves changing the coefficients in front of the chemical formulas to ensure that the same number of each type of atom is present on both sides of the equation.
A material that can be observed or measured without changing the identity of the material is called?
A physical property. This refers to characteristics of a material that can be observed or measured without changing the substance's chemical identity, such as color, density, or melting point.
How are elements differentiated by one another and why?
Each chemical element has a specfic number of protons - this is the identity.
Is sugar changing to alcohol a physical or chemical change?
Anything changing to a substance with a different identity is undergoing a chemical change.
