Radioactive decay is a chemical process that will occur indefinitely. It will eventually reach such a low level of radioactivity that any change is not measurable, but theoretically speaking this "reaction" never stops. Other than that I can't think of any reactions that will go on for that long without some change in their environment. Equilibrium reactions will shift regardless of how long ago they reached equilibrium if they detect some change (change in temperature, concentration of reactants or products, change in pressure or volume of their reaction vessel), but I don't think that's the sort of "goes on for years" you were asking for.
A chemical change is a chemical reaction.
We see the chemical reaction but we write the chemical equation.
yes ............... paint bubbling is a chemical reaction. when anything bubbles you know there is a chemical reaction.
the coefficients of a balanced reaction
The written statement that shows a chemical reaction is called an "equation". The representation of each reactant is called its chemical formula.
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
A chemical reaction occur.
Yes.
reactants
This is an endothermic reaction.
The burning of a wooden stick is a chemical process.
Corrosion.
Products. Products ----> Reactants.
It helps show you what goes on during a chemical reaction
Yes.
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! :)
