When something is alive, there are chemical reactions going on constantly within it. The technical definition of being deadis that of chemical equilibrium. When a system (for example, a beaker with chemicals inside it, or an animal) is in chemical equilibrium, there is no reaction that can take place without an input of energy. Since an animal in chemical equilibrim cannot do anything, it is considered completely dead.
So, in short, dying (that is, ceasing to be alive) is nota chemical change. Instead, dying is a lack of chemical change.

Is dead plant decomposes a chemical or physical change?
The decomposition of dead plants is primarily a chemical change. During this process, microorganisms break down the organic matter, leading to the transformation of complex molecules into simpler substances, such as carbon dioxide, water, and nutrients. This transformation alters the chemical composition of the material, distinguishing it from physical changes, which do not change the substances' chemical structures.
Is a leaf changing colors a chemical or physical change?
Leaves change colour because the green pigment (chlorophyll) is degraded, then other pigments like anthocyanins (red or purple) and carotenoids (yellow) are exposed. So the change is more chemical than physical. Leaves going brown are also caused by chemical changes, but it also means the leaf cells are dead or dying.
Rotting of dead animal is a chemical change or not?
Rotting of a dead animal is a chemical change because it involves the breakdown of molecules in the body, resulting in the formation of new substances. This process is driven by chemical reactions with microorganisms breaking down the organic material.
How do you dissolve a dead mouse in a deep water well?
It is not recommended to dissolve a dead mouse in a deep water well as it can contaminate the water supply. Instead, you should remove the dead mouse using appropriate safety precautions and dispose of it properly according to local regulations.
Why is it easier to determine the chemical structure of dead tissues than living flesh?
It is easier to determine the chemical structure of dead tissues because chemical reactions that break down tissue stop occurring after death. In living flesh, ongoing biochemical reactions can alter the chemical composition and structure, making it more challenging to analyze. Additionally, the preservation methods used on dead tissues can help stabilize their chemical structure for analysis.
Dead coral reef is pounded by waves into beach sand a physical or a chemical change?
Physical change
Is decaying matter a physical or chemical change?
It's a chemical change. A chemical change is any change that causes a substance to change into another substance. A sign to know whether it's a chemical change or not, are the changes in odor. When something decays the change in smell is very powerful. Therefore, it is a chemical change.
Is washing hair a chemical or physical change?
Washing hair is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, while a physical change only alters the physical properties, such as shape, size, or state, without changing the chemical makeup. When you wash your hair, you are simply removing dirt, oil, and other substances from the hair shaft without altering its chemical structure.

Does a dead mouse emit toxic fumes?
A dead mouse does not emit toxic fumes by itself. However, the decomposition process can release bacteria and viruses that may pose health risks, so it is important to safely and promptly dispose of the mouse and clean the surrounding area.
When a cat eats a mouse - is the mouse dead or alive?
The mouse is dead... cats will usually play with the mouse until they kill it then eat it
Rotting of dead animal is a chemical change or not?
Rotting of a dead animal is a chemical change because it involves the breakdown of molecules in the body, resulting in the formation of new substances. This process is driven by chemical reactions with microorganisms breaking down the organic material.
Why is Mickey Mouse dead?
micky mouse is dead because they are not making new series or episodes.
Why is frying egg a chemical change?
becausa it is like a dead kid ,you eat him then try to make him back but you cant it like that
I found a dead mouse in my living room and it looed like maggots were crawling out of it. the mouse couldnt have been dead 8 hrs. what could this mean?
The mouse was dead for about 3 weeks
Is mixing vinegar and baking soda a chemical or physical change and why?
Chemical. Vinegar is acidic - bicarniate when acidified produces carbon dioxide which bubbles out. This is a chemical change because the end-products (carbon dioxide, sodium acetate) are different species than the reactants (sodium bicarbonate, acetic acid). It is impossible to regain the initial state without the addition of new chemicals into the system. A physical change would be the freezing of vinegar. The reactants and the products are the same species (vinegar), and the initial state (liquid) can be regained by allowing the frozen vinegar to thaw.
