What is it called when a substance under goes a chemical change?
A chemical reaction occur.
When oxidation occurs does a substance undergo a chemical change or a physical change or both?
Oxidation is a chemical reaction; but a physical modification can also occur.
How are chemical properties different from chemical changes?
The difference between a chemical property and a chemical change is that the change is how the property of the chemical changes when it undergoes a chemical reaction.
What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
When oxidation occurs does a substance undergo a chemical a physical change or both?
Oxidation is a chemical reaction; but a physical modification can also occur.
What a substance changes into a different substance a change has occur what is created when chemical reactions join atoms together?
After a chemical reaction new compouds (called also products) are formed.
What for a given substance never change?
A substance's chemical composition, which is determined by the types and arrangement of its atoms, always remains the same regardless of physical or chemical changes that may occur.
When oxidation occurs does a substance undergo a chemical reaction a physical change or both?
Oxidation is a chemical reaction; but a physical modification can also occur.
When does a chemical bond occur?
no a substance is occurring
Is adding phenolphthalein to sodium hydroxide a chemical change?
No, adding phenolphthalein to sodium hydroxide is a physical change because it only involves mixing two substances together. A chemical change would involve a new substance being formed through a chemical reaction, which does not occur in this case.
Is squirting milk into a pail a chemical change?
No, squirting milk into a pail is not a chemical change; it is a physical change. The milk retains its chemical composition and properties when it is transferred from one container to another. A chemical change involves a transformation that alters the substance's chemical structure, resulting in new substances, which does not occur in this process.
What is chysical change?
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
