During a chemical change the form of a substance is altered but not its identity true or false?

The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.

∙ 9y agoThis is false. A physical change is when the form of the substance is changed, but not its identity. A chemical change turns it into something else.

What happens to the original substance during a chemical reaction?
The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
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.

The answer is true
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.

Is the flammability of acetone a physical or chemical property?
A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated. (Wikipedia)A physical property is any aspect of an object or substance that can be measured or perceived without changing its identity. (Wikipedia)A substance's ability to dissolve in acetone would be classified as a chemical property, since, technically, dissolution is a chemical reaction for which the following generic equation holds:AB -> A+ + B-where A denotes the cation and B denotes the anion. Furthermore, dissolution does change the internal structure of the substance, changing it from a neutral compound to a solution of ions.
What changes during chemical change?
In a Chemical Change, atoms rearrange to form one or more new substance. They do this by breaking bonds and forming new ones.The identity of the substance undergoing the change is altered. In short: it depends on the chemical change.You would see a gas given off, the colour might change and it may change states that can not be turned back to what it was.hope I've answered your questio :)During a chemical change, the properties change and a new substance is formed. Temperatures change, colors change or smoke is present, and/or gas/bubbles are releasedA new substance is created and heat, light, or gasses are given off.Even though the persons answer is very well explained (down below) but I think you are looking for a more simple answer which is: Burning PaperA new chemical is formed. Evidence of this is cooling or heating of the samples as well as bubbles meaning a gas is formed.Vinegar and baking soda form a gas and it bubbles.Forms different substance.
What is new substance that is formed during a chemical reaction?
That would be the product of the chemical reaction.
What is the substance on which an enzyme acts during a chemical reaction?
a catalyst
What is a substance formed during a chemical reaction is called?

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.
