Sodium with HCl gives NaCl and H2
2Na + 2HCl -> 2NaCl + H2
The metal: sodium. The acid: hydrochloric acid.
Any reaction occur between these two reactants.
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
The residue from the reaction between ferric chloride and sodium hydroxide would likely contain iron hydroxide as a major component, with sodium chloride also present because of the initial reactants. The specific composition would depend on the stoichiometry of the reaction and any other impurities present in the starting materials.
When solid sodium chloride dissolves in water, the resulting sodium and chloride ions are said to be the products. Product is a general term for any substance which results as the result of a chemical reaction. Thus, if the solution was to be boiled and the ions formed into a solid, the products and reactants would be reversed.
Reactants would be the elements or compounds that are chemically combined to form a new compound. An example would be sodium and chlorine combine to form sodium chloride. In this example, sodium (Na) and chlorine (Cl) would be the reactants and Sodium Chloride (NaCl) is the product.

Electrolysis of molten sodium chloride: yield sodium and chlorine.Electrolysis of sodium chloride water solution: yield hydrogen, sodium hydroxide and chlorine.
If you mean element, that would be Hydrogen. If you mean compound, that would be Chloride. If you mean in sea salts that make up seawater, that would be Sodium. However, Chloride and Sodium go hand in hand, so Chloride gains an electron and Sodium loses one; then the two bond to create salt.
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
Evaporate the water.
Mixing iron III chloride and sodium hydroxide would result in a chemical change. The reaction between the two compounds forms iron III hydroxide and sodium chloride, which are new substances with different chemical properties than the original reactants.
you could burn hydrogen in air, where the oxygen in the air would combine with the hydrogen to form water vapor which could be condensed on a cold surface. Also, the general reaction Base + Acid gives Salt + water for example Hydrochloric acid reacting with Sodium hydroxide gives water plus sodium chloride. Many other reactions have water as a by-product.
