Chemical change

∙ 11y agoIt's a chemical change, though the type of reaction depends on the battery. A rechargeable battery is a repeatable reaction. First, you consume the electricity in the battery. Then, when you go to re-charge it, you apply electricity which reverses the chemical reaction. Then when you use it again, the reaction occurs again and it depletes itself. Each time you do so the battery becomes a tiny bit less efficient, which is why phone or computer batteries slowly get worse over time.
A non-rechargeable battery is much simpler. It tends to be much longer-lasting and more efficient because it's just a one-time reaction, however after the reaction it is impossible to re-use the materials.

Is using scissors to cut paper a physical or chemical change?
It is a physical change, as the chemical integrity remains the same.
Is silver melts when using a blow torch a chemical or physical recation?
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
Is a magnet being used to remove iron shaving from dirt is an example of a chemical change?
It is a physical process. Not really a change of any kind.
Is using hot water to expand a metal cup a physical or chemical change?
Physical- the metal isn't changing. If you burned it, then perhaps it would be chemical. But it's physical.

Melting a nail physical or chemical change?
Physical, if you are not using any chemicals in the process it is a physical change.

It is a physical change, as the chemical integrity remains the same.
Is using acid to clean metal a physical change?
No, it is a chemical change.
When bleach spills on a shirt is it a chemical change?
Yes, it it a chemical change because you can't get the same exact t-shirt without out using chemical means to take it out.
Is silver melts when using a blow torch a chemical or physical recation?
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
If you had a mixture of two substances and had your choice of using a physical change or a chemical change to separate them which would you prefer?
Physical change is preferable because it is easier than chemical method.
Is a plant using Co2 and H20 to form 02 and sugar a chemical or physical change?
A chemical change. If the identity of of the chemicals involved change in identity, it is a chemical change.
Is using electricity to separate water into hydrogen and oxygen a chemical change?
physical change
Is a magnet being used to remove iron shaving from dirt is an example of a chemical change?
It is a physical process. Not really a change of any kind.
