because it can't be changed back into it's normal form. the smell changes, which also tells you when a chemical change is taking place.
What else can I help you with?
What processes is not a physical change drying wet clothes cutting snowflakes out of paper light a match from a matchbook?
Ignition of a match is a chemical process.
Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
Is burning a match physical or chemical matter?
Burning a match involves a chemical reaction where the match tip reacts with oxygen in the air to produce heat and light. This process involves both physical and chemical changes, as the match undergoes combustion to produce new substances such as ash and smoke.
Is Lightening a match a physical change?
No Physical changes are state changes such as freezing, melting, evaporation, condensation, boiling. Physical changes do not produce "new" substances. Lighting a match would be an example of a chemical change in which the substances on the match, and eventually the wood or paper of the match are chemically altered to produce water, carbon dioxide, and other "new" compounds.
Is a lit mach a chemical change?
Yes it is. A chemical change is one in which new products are formed.When you light a match, combustion occurs, meaning that CO2 and H2O are produced.Therefore it is a chemical change.
What process is not a physical change drying wet cloths cutting snowflakes out of paper lighting a match from a matchbook?
Ignition of a match is a chemical process.
What one what processes is not a physical change drying wet clothes cutting snowflakes out of paper lighting a match from a matchbook?
The answer is lighting a match box because when doing so, the match goes into flames and flammability is a chemical change. When cutting a snowflake, the substances do not change, neither does it change when drying wet clothes. The person earlier said drying wet clothes, but he/she is wrong because when you dry wet clothes, the water goes through a physical change called evaporation, which is NOT a chemical change. I hope this helps. Good luck on your chapter assessments(I'm doing mine too). :)
Lighting a match a physical change or chemical change?
Lighting a match is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Is lighting a match a chemical change?
Yes, lighting a match is a chemical change because the chemicals in the match head undergo a chemical reaction when exposed to heat from friction, resulting in the release of energy in the form of light and heat.
What processes is not a physical change drying wet clothes cutting snowflakes out of paper light a match from a matchbook?
Ignition of a match is a chemical process.
Is lighting your match a physical or chemical change?
Mainly chemical (oxidation).
What processes is not a physical change drying wet clothescutting snowflakes out of paper lighting a match from a matchbox?
lighting a match from a matchbox is a chemical change.
Is lighting a match from a matchbox a physical change?
Yes, lighting a match from a matchbox is a chemical change, not a physical change. When the match is struck, the chemicals on the match head react to produce heat, light, and a flame. This transformation is a chemical reaction, not just a change in physical state.
Is lighting a match physical change?
This is a little tricky. Striking a match is a physical act, but it does induce chemical changes. It depends on exactly what you mean by "lighting", ultimately. The end result is definitely a chemical change.
Is the ignition of matches a chemical change?
Lighting a match starts a chain reaction which boosts the materials of the match tip, the wood with oxygen. These process changes the substance chemical formula, thus chemical change happens.
Is lighting a match a chemical change change?
Burning a match is a chemical change. Whether the act of lighting it is makes for an interesting philosophical discussion. Exactly what do we mean by lighting it? Is it the movement of striking? In which case, no, that's just motion, so that's physical. Is it the application of heat, from friction or otherwise? Again, no new substance is produced at that point, so no. Do we mean the beginning of flame? Yes, as soon as it's burning, new substances are being produced.
How is lighting a match a chemical change?
When a match is lit, the chemicals in the match head undergo a chemical reaction resulting in the production of heat, light, and new chemical compounds like carbon dioxide and water vapor. This transformation of the chemical composition of the match represents a chemical change.
