Solid sodium chloride decomposes into chlorine gas and solid sodium . Write a balanced chemical equation for this reaction.

2NaCl > Cl2 + 2Na

Explanation:

2 moles of sodium chloride is irreversible to chlorine gas plus 2 moles of solid sodium

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

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.
