Answer:
Explanation:
A new Material is formed.
Basically, Chemical changes differ from Physical changes because in chemical changes, Substances have the ability to become a different substance.
Example:
Water to ice is a physical change because it is still water despite being a solid from liquid.
A Magnesium strip placed in CuSO4 solution made the Mg strip turn into a new substance which is MgSO4. this is a Chemical change because Mg has now become a different substance called MgSO4.
High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.
I hope this helps you.
Answer:
i think kinetic energy sorry if I'm wrong.
Answer: By using electrolysis.
Explanation:
Electrolysis is a chemical change produced by sending an electric current through a compound. Electrolysis works because the hydrogen and oxygen ions are held together by an electric attraction.
