Some chemical changes are baking a cake and a rusting bicycle.
Another chemical changes could be:
An example of a chemical change would be Photosynthesis. Sunlight + CO2 + H2O(water) --> Glucose (C6H12O6) + O2(Oxygen we breathe)
Another would be the old coke and mentos. gas is released, that's how you know it's a chemical reaction and not a physical change.
burning , rusting , rotting etc.
some chemical changes can be reversed but they are hard to reverse usually
Some chemical changes are reversible, others are not.
Freezing a popsicle
Not necessarily. In some chemical changes a compound is broken down into its elements.
because it mixes substances that makes a chemical change
hot cold
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.
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.
There are no physical changes. there are only chemical changes.
Some examples of chemical changes that release energy include combustion reactions, oxidation reactions, and certain types of nuclear reactions. These reactions typically involve the breaking of chemical bonds and the formation of new, more stable bonds, resulting in the release of energy in the form of heat or light.
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
No, physical changes involve a change in appearance, texture, or state of matter without altering the chemical composition of the substance. In contrast, chemical changes result in the formation of new substances with different chemical properties.
