It would depend on your definition of a chemical.
A chemical is: "a substance produced by or used in a chemical process."
And, water is a chemical because it is be used in chemical reactions such as neutralization, redox, etc.
I believe what you're asking though is if water is a chemical substance: "a material with a definite chemical composition."
Water is also a chemical composition because of its electron configuration in its valence shell which defines its chemical properties.
H2O. This means that water chemically consists of 2 parts hydrogen and 1 part oxygen.
HgO
C3H8O3
CO
Formula: Ba3P2
it produces glucose and oxygen
It is possible to change water into another form. H20 may be changed into other forms through chemcial reactions. A process known as electrolysis breaks water into Hydrogen and Oxygen.
tetraoxosuphate(vii)acid
Its the change of one substance into another substance.
Yes, hydrolysis is a chemical reaction.
Pb, atomic element, metal
Es, atomic number 99
