What happens to the chemical properties of substances during a chemical reaction?

In a chemical reaction only the atoms show in the reaction and they can end up in a product. Also, in a chemical reaction the reenact with one another to break down the product. They can also bond and rearrange the atoms to make a new product.

Explanation:

Hope this helps :)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
