The reaction of sodium and chlorine to form salt is best described as an?

The chemical reaction that takes place between sodium and chlorine to form table salt (NaCl) gives off heat; therefore, this can be described as an exothermic chemical reaction.

Brainliest answer please?

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.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
