When sodium undergoes a chemical reaction with chlorine, they form sodium chloride, which is commonly known as table salt. The reaction is highly exothermic, meaning it releases a significant amount of heat energy. Sodium loses an electron to become a positively charged ion (Na+), while chlorine gains an electron to become a negatively charged ion (Cl-), resulting in the formation of an ionic bond between the two elements.
When a compound undergoes a chemical reaction, its chemical bonds are broken and reformed to result in new substances with different chemical properties. This process can involve changes in energy, formation of new bonds, and rearrangement of atoms. The reactants are transformed into products through the rearrangement of atoms.
Silver chloride undergoes a photochemical decomposition reaction in the presence of light, breaking down into elemental silver and chlorine gas. This reaction can be used in photography to develop images on film.
When ethanol is treated with PCl5, it undergoes a substitution reaction where the hydroxyl group (-OH) of ethanol is replaced by a chlorine atom. This results in the formation of ethyl chloride and phosphorous oxychloride as byproduct.
An example of a chemical reaction that happens in the home and needs to be heated before it starts is baking. When baking a cake, for instance, the batter undergoes a series of chemical reactions that require heat from the oven to activate the leavening agents, causing the cake to rise and bake properly.
When sulfur is mixed with oxygen, it undergoes a chemical reaction that forms sulfur dioxide. This reaction is exothermic, meaning it releases heat energy. The resulting compound, sulfur dioxide, is a colorless gas with a sharp odor.

sodium and chlorine (Na and Cl) chemically combine
In the reaction between chlorine gas and bromide ions, the chlorine gas oxidizes the bromide ions to form bromine gas and chloride ions. This is a redox reaction where chlorine undergoes reduction by gaining electrons from bromide ions.
Calcium + Chlorine --> Calcium Chloride Ca + Cl --> CaCl Balanced Equation: Ca + Cl2 --> CaCl2 Calcium has a 2+ charge, while chlorine has a 1- charge. Therefore you need two chlorine ions to balance the charges.
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide. The total mass remains the same since no mass is lost or gained during a chemical reaction.
When an object is burned, its matter undergoes a chemical reaction and is converted into different substances, such as ash, gases, and heat. This process is called combustion.
Silver chloride undergoes a photochemical decomposition reaction in the presence of light, breaking down into elemental silver and chlorine gas. This reaction can be used in photography to develop images on film.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped

The absorption of water is not a chemical reaction.
A chemical change involve a change of composition.
