Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
Is the dissolving salt in water a chemical or physical change?
The dissolving of salt in water is considered a physical change, not a chemical change. This is because no new substances are being formed during the process; the salt molecules are simply breaking apart and dispersing throughout the water.
When states of matter change so does the chemical composition of the molecule?
No, the chemical composition of a molecule remains the same when it changes states of matter. Changes in state involve the arrangement and movement of molecules, but the actual chemical makeup of the molecules remains unchanged.
Reaction that break apart large molecules are involved in which type of digestion?
chemical
Is dissolving of salt physical change or a chemical change?
The dissolving of salt in water is a physical change because it does not result in a chemical reaction. The salt molecules are simply breaking apart and becoming dispersed in the water, but there is no change in the chemical composition of the salt.

When a sodium hydroxide dissolves in water is it a chemical change?
When sodium hydroxide dissolves in water, it undergoes a physical change as the sodium hydroxide molecules split apart into ions, which are then surrounded by water molecules. This process does not involve a change in the chemical composition of the sodium hydroxide molecule itself.
Chemical reactions that take apart molecules?
The chemical process by which molecules are broken down into their smaller components is called catabolism.
Is water evaporating into steam physical or chemical?
It's a physical change because no new substances are formed, the molecules simply get further apart.
Is water evaporating into steam chemical or physical change?
It's a physical change because no new substances are formed, the molecules simply get further apart.
What that break apart large molecules are involved in which type of digestion?
chemical
A change in which one or more substances combine or break apart to form new substances?
chemical change
Is melt a chemical or physical?
Melting is a physical change because it does not involve a change in the chemical composition of the substance. When a substance melts, its molecules or atoms move apart, resulting in a change in its physical state from solid to liquid.
Reaction that break apart large molecules are involved in which type of digestion?
chemical
Is explode physical or chemical change?
Explode is a rapid physical change that occurs when substances release a large amount of energy in a short period of time, causing them to break apart or burst. It is not a chemical change because the substances involved do not undergo a change in their chemical composition during the process.
