The chemical change that happens to form water is when pure hydrogen gas (H2) combine with pure oxygen gas, they get involved with one another, and the slow rate of reaction between the two, create water, but very slowly. The other name for water of course is H2O.

Is a physical change what happens when chemical bonds break and new bonds form?
NO, that's an example of a CHEMICAL change
When water changes is it a chemical change?
no. when water boils it is a physical change, because the actuall chemical structure is still H2O, it is just in the form of steam.
If tap water and soap form an insoluble deposit is this a physical or chemical change?
The formation of a precipitate is a chemical change.
What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
What type of change had to happens for elements to form water?
A chemical reaction/bond.
What kind of change happens when hydrogen gas and oxygen gas react burn and form water?
This reaction is a chemical change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is a physical change what happens when chemical bonds break and new bonds form?
NO, that's an example of a CHEMICAL change
Is mixing drink mix into water a physical or chemical change?
chemicasl because the water does not change its form
When water changes is it a chemical change?

What is the name of a chemical reaction that happens when chemicals change to a new form?
substance
If tap water and soap form an insoluble deposit is this a physical or chemical change?

Is reactivity with water a physical or chemical change?
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
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 a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
