∙ 12y agoAutomotive Engines : Vaporized fuel rapidly oxidizes (explodes), releasing energy.
Rusty Nails: A chemical reaction between the iron in steel and oxygen in the atmosphere causes rust.
Photographic film: There is a chemical reaction on the film wherever light hits it.
Batteries: Chemical reactions within batteries produce electrons. These are called electrochemical reactions.
Glow Sticks: A chemical reaction excites atoms causing the stick to glow.
Homemade Volcano: When baking soda and vinegar are combined, they erupt as carbon dioxide gas is released.
Fizz Fizz: Dropping an Alka-Seltzer tablet in water makes a bubbling chemical reaction (effervescence).
An Old Fruit Salad: Cut a piece of fruit open and it soon turns brown, reacting to the oxygen in the air.
When You Light A Paper or Wooden Match: All burning is rapid oxidation.

Can a chemical change be undone?
Some chemical changes are reversible, others are not.
What are some kinds of chemical changes that release energy?
Chemical changes that release energy are called Exergonic in biology, and Exothermic in chemistry. An example of these is respiration and fermentation.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Why is Wood burns to form black charcoal a chemical change?
It changes properties.Physical Changes:Physical changes are changes in the appearance but not in the chemical properties. Some physical changes can be undone so the item can be put back to almost its past form.Chemical Changes:Chemical changes are the changes in chemical properties. Chemical changes also change in appearance and/or leave behind traces to prove that a chemical change occurred. Chemical changes create a new substance when they happen, e.g., cooking an egg. Chemical changes cannot be undone as the molecules, patterns and properties have been changed.How to tell them apart:The way to tell the difference between chemical and physical changes is by the changes that it went through. There may be clues that a chemical change appeared because of sound, light, gas production or an odour. A physical change does not involve any of these.
What is it called when one or more substances change into one or more new substances?
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
What are some chemical changes caused by changes in temperature?
Freezing a popsicle
Does chemical change make a compound?
Not necessarily. In some chemical changes a compound is broken down into its elements.
What are some cooking chemical changes?
because it mixes substances that makes a chemical change
What is some chemical and physical changes from copper?

What are some physical and chemical changes in cooking?
hot cold
What are some chemical changes when cooking?
Some chemical changes when you are cooking are:burning the foodOVERcooking itUNDERcooking itsorry for only three examples. those are the ones that i can only think of so far.
Are chemical changes reversible?
I would argue that in theory all chemical changes are reversible. However it is certainly true that considerations of enthalpy and entropy mean that some are totally impractical to reverse.
What are some kinds of chemical changes that release energy?
Chemical changes that release energy are called Exergonic in biology, and Exothermic in chemistry. An example of these is respiration and fermentation.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
What are some chemical reactions and changes that happen when cleaning pennies?
something
