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 of the following involves a change in the identity of the matter undergoing change?
A change in the identity of the matter undergoing change involves a chemical change. During a chemical change, the substances involved undergo a transformation that results in new substances with different properties. Examples include reactions such as rusting of iron or combustion of wood, where the original materials are fundamentally altered. In contrast, physical changes do not alter the chemical identity of the substance.
What is the form or appearance of matter altered during a change?
During a change, the form or appearance of matter can be altered through physical or chemical processes. In physical changes, such as melting or dissolving, the substance retains its chemical identity but changes state or shape. In chemical changes, such as combustion or rusting, the matter transforms into new substances with different properties. These alterations can affect color, texture, state (solid, liquid, gas), and other physical characteristics.
What property of matter can be identified without changing the identity of the substance?
The property of matter that can be identified without changing the identity of the substance is called a physical property. Examples of physical properties include color, smell, freezing point, boiling point, and density. These characteristics can be observed or measured without altering the chemical structure of the substance. In contrast, chemical properties involve changes to the substance's identity during a chemical reaction.
Can the chemical properties of a substance be observed without changing the substance?
physical properties

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
Can the chemical properties of a substance be observed without changing the substance?
physical properties
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.
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.
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.
