How does burning produce new materials?
Burning is a term which generally describes the chemical reaction combustion. Combustion always involves the reaction of a substance with an oxidizing agent to yield products which are either components of the original substance or different compounds which contain the same atoms. So, the process of combustion always yields a substance which is different from the original compound (i.e. forms a new substance) along with a lot of heat. This heat allows the substance to continue burning until no reactants remain or something inhibits the reaction - usually by removing access to one of the reactants or removing energy form the system. Most organic matter will burn to produce large quantities of carbon dioxide and water.
A combustion reaction occurs when a substance, usually containing carbon reacts with to produce energy in the form of heat and light?
oxygen
What is light-depent reaction in photosynthesis?
It means that for a reaction (usually chemical) to take place, light is needed. An example of this can be seen in photosynthesis.
What is the decomposition reaction occurs in the presence of heat,?
Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. The reaction is usually endothermic because heat is required to break the bonds present in the substance.
What is a neturalisation reaction?
A neutralization reaction is a reaction between and acid and a base forming a salt. Usually water is formed too, but not always. Arrhenius acids and bases always produce water, but acid-alkai reaction produce water and a metal salt.

oxygen

When heating a substance what happens?
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.

A combustion reaction occurs when a substance usually containing reacts with oxygen to produce energy in the form of heat and light.?
oxygen Wrong! its CH4 + 2O2 → CO2 + 2H2O
What is a chemical reaction is endothermic?
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
What individual hypersensitivity to a substance usually antibody-antigen reaction is known as?
It is an allergy
What is the measured amount of a productobtained from the chemical reaction?
This is usually referred to as the ACTUAL YIELD of that substance.
What is a titration reaction?
A titration reaction is a chemical technique used to determine the concentration of a substance in a solution. It involves the gradual addition of a known concentration of another substance, called the titrant, to the solution until a reaction is complete. The endpoint of the reaction is usually detected using an indicator or an instrument, allowing for the calculation of the concentration of the unknown substance.
What is the decomposition reaction occurs in the presence of heat,?
Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. The reaction is usually endothermic because heat is required to break the bonds present in the substance.
What is a chemical reaction between a substance and air called?
A Combustion reaction. It usually happens between a gas and oxygen. The products are CO2 and H2O.
