Is it true during a chemical change the form of a substance is altered but not its identity?
Yes, during a chemical change, the chemical composition of the substance is altered, which means new substances are formed with different properties. However, the identity of the original atoms remains the same, as they are rearranged to form new compounds.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
What property of a substance does not change when it turns into gas?
The chemical identity of a substance remains the same when it turns into a gas. The type of atoms and their arrangement within the substance do not change during the phase transition from liquid to gas.
What happens to the composition of a substance during a chemical change?
Atoms are rearranged, heat may be given off, changes in color and odor might occur, or a gas or precipice may be formed. The composition is changed, and the above are signs of a chemical change.
Is limestone gives off carbon dioxide when heated physical or chemical?
When limestone is heated, it undergoes a chemical reaction called thermal decomposition, where it breaks down into calcium oxide (quicklime) and carbon dioxide gas. This is a chemical change because the chemical composition of the substance is altered during the process.
Is it true during a chemical change the form of a substance is altered but not its identity?
Yes, during a chemical change, the chemical composition of the substance is altered, which means new substances are formed with different properties. However, the identity of the original atoms remains the same, as they are rearranged to form new compounds.
What takes place during a chemical change?
During a chemical change, the identity and composition of a substance are altered as new chemical bonds are formed or broken. This change is usually irreversible and produces a new substance with different chemical properties compared to the original materials. Examples include combustion, oxidation, and digestion.
Is a chemical property a noun or a verb?
The compound word 'chemical property' is a noun, a word for the characteristic of a substance observed during a reaction in which the chemical composition or identity of the substance is changed; a word for a thing.
What happens when a pure substance undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What happens to the identity of a substance when it makes a physical change?
there is to types of change to a substance chemical and physical in a physical change the result is a mixture also most times you can change your end result into what you started with e.g.freeze-melt evaporate-condesate
When the substance undergoes a chemical change its identity deos not change?
That's correct. In a chemical change, new substances are formed through rearrangement of atoms, but the identities of the original atoms remain the same. This is because atoms are not created or destroyed during chemical reactions, they simply rearrange into new combinations.

What process happens when a substance undergoes a chemical change?
During a chemical change, the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Bonds between atoms are broken and rearranged to form new molecules. This process is typically accompanied by the release or absorption of energy.
What reaction of matter will stay the same during a physical change?
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
