Water can be broken down by the chemical process called electrolysis. An electrical current is passed through water with an electrolyte added to it. The electrical current breaks down the water into hydrogen and oxygen gas that bubble up from the electrodes in the water.
Chemical Change
NO!!!!! It is an element in its own right. Ylou will find it in ther Periodic Table.
The correct answer would be Ammonia
because they become oxidized and reduced when glucose is broken down in photosynthesis and cellular respiration.
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
Chemical you are breaking down the water and it would need to under go another chemical change to become water again.It is always chemistry which breaks down molecules (H2O) into its elements (H2 and O2)
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
No. It is an element and fundamentally already as "broken down" as possible.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
of course, by the intermediate of chemical reactions
Electrolysis will turn water into hydrogen and oxygen gas.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
yes they can
