Apple ripening is a chemical reactn
(new person answering)
It is a chemical reaction because when you think about it, an apples ripening only happens once; apple buds on a tree, goes yellow, goes green, goes red-ish, goes juicy red, is either eaten or falls off the tree, goes mouldy and shrivels up.
Hope this answer helped and was improved than the other answer! :)
It's a chemical reaction because an apple only ripens once
no cos banananas did
Involving chemical reactions it is a chemical process.
Reversible changes are the chemical reactions that can be reversed, however most are non reversible. The ones that can be reversed is because the reaction can flow both ways.
Is the lighting of a bulb a reversible or an irreversible change
Chemical reaction; this involves the breaking and forming of bonds between atoms which will change the properties of the substance (ex: rusting)
a physical change is reversible but a chemical change is irreversible
Digesting a banana is a chemical reaction, an ireversible change.
it's a reversible change
A reaction which cannot be reversed is called an Irreversible reaction.
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Ripening is a chemical process.
Not chemical reactions, but change of phases
A chemical reaction is irreversible, while a physical change is reversible. Fire is a chemical reaction because you can't get back the products.
no it is not reversible because a chemical reaction has taken place that cannot be reversed.
Dissecting a banana is a physical change, not a chemical reaction. It involves physically separating the banana into smaller pieces, but the chemical composition of the banana doesn't change. A reversible change would be when you freeze the banana slices and then thaw them, as this can be reversed.
Involving chemical reactions it is a chemical process.
Firing a forest is a chemical change because you change a wood into ashes and never reverse it back again
Digestion involve chemical reactions, it is a chemical and mechanical process and is irreversible.
