1. The boiling of water is a physical phenomenon, a change of phase.
2. But at very high temperature (2 000 0C or more) water can be thermally dissociated in hydrogen and oxygen; this is a chemical phenomenon.
It is a chemical change, because the borax reacts to the heated water.
This is a chemical reaction.
Sodium polyacrylate and water do not undergo a chemical reaction when mixed. Instead, the sodium polyacrylate absorbs water and forms a gel-like substance without any chemical bonding.
Yes, making caramel sauce involves a chemical reaction called caramelization. This reaction occurs when sugar is heated, causing it to break down and turn into a golden-brown liquid with a deep, rich flavor.
Yes, you can make a chemical reaction without making the product an inert gas. For example, if you run an electric current through Hydrogen and Oxygen, the product is Water, or H2O. Water is not an inert (noble) gas, so you can make a chemical reaction without making the product an inert gas.
The che chemical equation is:2 H2 + O2 = 2 H2O
it's a reversible change
im pretty sure a chemical reaction occurs then an compound is made
Dissolving stock cubes in water to make soup is a physical process, not a chemical reaction. The cubes are simply breaking apart and dispersing in the water without any chemical bonds being formed or broken.
No.
I got a chemical reaction in the science lab today.
This chemical reaction is called neutralization.
