Adding electric current to separate hydrogen from oxyge.
What else can I help you with?
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
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
What would cause a chemical change in water?
Adding an acid or a base to water can cause a chemical change by altering the pH. Another way to induce a chemical change is through electrolysis, where an electric current is passed through the water to break it down into hydrogen and oxygen gas.
How would you cause a chemical change to vinegar?
For example adding a base.
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.
Is baking soda mixed iodine solution a chemical change?
Chemical, When something changes in color, it is a sign of a chemical change.
How does chemical change happens in photosynthesis?
it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.
Is dissolving salt in water a chemical change?
this is a chemical change cause you can't return it back to solid salt
Which change in climate would likely cause the greatest increase in chemical weathering of local bedrock?
An increase in temperature and precipitation would likely cause the greatest increase in chemical weathering of local bedrock. Higher temperatures can accelerate chemical reactions, while increased precipitation can provide more water to facilitate the weathering process.
How would you cause chemical change in vinegar?
Add baking soda (watch out, it will fizz.)
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
