What substance can be decomposed by a chemical change Ne N2O HF or H2O?
All except neon, with atomic symbol Ne, of the entities shown the question by their chemical formulas or symbols can be decomposed by chemical change.
Can h 2 o be decomposed by chemical change?
Yes, H2O can be decomposed by electrolysis. 2H2O --> 2H2 + O2
Is an ice cube and water a physical or chemical change?
A physical change because the substance does not change. It is still H2O, but in a different form.
What is a chemecal change?
A chemical change (as opposed to a physical change) is when the actual chemical makeup of a substance changes. For example, Na+Cl->NaCl. A physical change on the other hand would be more along the lines of H2O(s)->H2O(l), (melting ice).
Is Chemical formula H2O Chemical Or Physical Properties?
Neither. It defines the substance but does not characterize it.

Is this a chemical change or physical change water freezes and turns into ice?
It's a physical change because the substance is the same before and after only changing form. In other words, water's chemical formula is H2O and ice's chemical formula is also H2O, so they are the same substance. Therefore it is a physical change.

What is a physical change rather than a chemical change?
`A physical change is one in which matter is changed into another physical state without changing its chemical constitution(eg-ice melts to water,in both case substance is H2O).A chemical change is where there is a chemical change of the substance during the process(eg-CaCO3 is heated to form CO2 and CaO,here the new substance formed is unrelated chemically to parent substance.)
What chemical substance is formed when the -OH and -H are joined?
H2O is the chemical formula of water.
What is the most abundant chemical substance in the human body?
This substance is water, H2O.
Is the freezing of H2O a chemical or physical change?
Freezing of H2O is a Physical Change.
Is h20 a physical or chemical property?
H2O is not a property, it is a substance with physical and chemical properties.
Is Chemical formula H2O Chemical Or Physical Properties?
Neither. It defines the substance but does not characterize it.
Is H2O a compound or mixture?
H2o is a compound because it retains its own property.
