It is 65% distilled water and 35% Sulfuric Acid.
The chemical composition remain unchanged.
The chemical composition of water remain unchanged.
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).
inposable
standard chemical battery contains chemical composition . as i know it may be lead acid battery it contains Lead and Sulfuric acid and water the lead is used for make electrodes and acid is used as electrolyte . this is used for provide back- up to ups and DC to AC converter (inverter) widely.
The chemical composition of water remain constant.
The chemical composition of water is H2O.
the positive plate is Pb the negative is PbO2 and the acid is H2SO4.
Boiling water is a physical change because it does not change the chemical composition of the water.
Because water is a compound, a type of pure substance, which has a definite composition.
No, it is a physical change because the chemical composition of the water or mud does not change.
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.
