Is it a physical change or a chemical change when substances combine to make new substances with new properties?
Chemical change.
Does a chemical change make a new substance?
some chemical reaction can.
What describes a substances ability to change into a new substance with different properties?
The chemical property of a substance relates to its ability to undergo a change. It transforms the substance into different substances.
What change is it when elements rearrange to make a new substance?
Chemical change.
Can a chemical change make a new product?
All chemical changes make new products that are different from the reactants in their chemical and physical properties.
Why atomic number not change during a chemical reaction?
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
Which change forms a new substance?
The change were new material is produce is called chemical change.
Is acidity a chemical change?
Acidity itself is not a chemical change; rather, it is a property of a substance that reflects its ability to donate protons (H⁺ ions) in solution. However, when an acidic substance reacts with a base, a chemical change occurs, resulting in the formation of new products, such as water and salt. Thus, while acidity can influence chemical changes, it is not a change in itself.
Is bleaching hair a physical change or chemical change?
when you bleach your hair it is a chemical change,because you are adding the chemical from the bleach to your hair and "you can't change it back to the old". chemical change: you can't change it back to the old and it makes a new subtance. physical change:it does not make a new subtance and it is still the same object.
