Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
Electrolysis of water is a chemical change. Exposing sodium chloride to sunlight would cause some heating, but no chemical changes.
Is it a chemical or physical change when a scientist break-up water into oxygen and hydrogen gas?
It would be chemical change.
Food coloring to water is Physical or Chemical change?
Physical change because the two substances do not bond together. If you waited for a long time the water and the food coloring would separate.
Is water freezing at zero degrees Celsius physical or chemical change?
Physical. Ice is simply the solid form of water. If it were a chemical change, then ice would not be water.
Is H2o a chemical change?
H2O is the compound water. Forming it from other things would be a chemical change. Using it to react with other substances and form new substances would also be a chemical change. But water just sitting there is not a chemical change. EX: hydrogen(gas) + oxygen(gas) forms water (chemical change) Water + sodium forms sodium hydroxide and hydrogen (gas) (chemical change) BUT water + sugar makes a sugar water solution (not a chemical change) nothing new was made, the sugar just dissolved and the water is still water

What would cause a chemical change water?
Adding electric current to separate hydrogen from oxyge.
Is movement a chemical change?
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc
Is reacting with water a physical change or chemical change?
it would be a chemical property because is changes

How would you cause a chemical change to vinegar?
For example adding a base.

Is reacts with water physical or chemical change?
it would be a chemical property because is changes
Is cornflour and water a physical change?
Adding cornflour to water is a physical change. The reason this process is classified as such is that it does not change the chemical identities of the substances involved, which is the criterion for a process to be considered a chemical reaction. Technically, the cornflour would slowly hydrolyze in water, which would be a chemical reaction.
Is concrete setting a physical or chemical change?
It would be both. It's a physical change because it is changing state and a chemical change because water is being evaporated.
