Does melting ice changes the chemical composition of water?
The chemical composition of water remain unchanged.
What characteristics of water remains the same no matter what is dissolve in it?
The chemical composition of water remain constant.
Is water evaporates into stream a physical property?
No, water evaporating into steam is a physical change rather than a physical property. A physical property is a characteristic of a substance that can be observed without changing the substance's chemical composition, whereas a physical change is a change in the substance's state or appearance without altering its chemical structure.
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 evaporating water a physical change or a chemical change?
When water evaporates, it is a physical change.You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is water still H2O after it evaporates?
no, then it is gasEDIT: The chemical formula for pure water is always H2O - regardless of whether it's in the form of ice, water or steam ! Snakester1962 (Supervisor)
When water evaporates does the water change?
Yes and no. Yes because it does keep its form kind of when it evaporates. All that happenes is that it just turnes into a less dense form. Then no because when it evaporates it is a gas until it changes again.
Does melting ice changes the chemical composition of water?
The chemical composition of water remain unchanged.
Is dissolving in water a chemical or physical property?
Dissolving in water is a physical property because it does not change the chemical composition of the substance. The molecules of the substance are simply surrounded by water molecules and dispersed throughout the solution without undergoing a chemical reaction.
Why is it chemical when water is separated into o2 and h2?
It is a chemical change (reaction) because the chemical composition of the products (O2 and H2) is different from the chemical composition of the water (H2O).
What kind of change is taken when paper is burned?
Chemical Change: a usually irreversible chemical reaction involving there arrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance: The formation of ruston iron is a chemical change.It is a chemical change.A physical change is a change that does not change the chemical composition of the material. When water evaporates and condenses it is still water even though it looks different, the same as if you cut or crumple paper. It may look different, but its chemical composition has not be altered.
What characteristics of water remains the same no matter what is dissolve in it?
The chemical composition of water remain constant.
What is water's element combination?
The chemical composition of water is H2O.
When ethyl alcohol evaporates is it a chemical or physical change?
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
Is water evaporates into stream a physical property?
No, water evaporating into steam is a physical change rather than a physical property. A physical property is a characteristic of a substance that can be observed without changing the substance's chemical composition, whereas a physical change is a change in the substance's state or appearance without altering its chemical structure.
Is dissolves in water physical property or chemical property?
Its A physical change. When you boil water under a stove, The water evaporates and the chemical stays in the..pan or whatever you put in it.
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.
