I have this same worksheet that has the following questions that I have to answer: Iron rusts. Sodium hydroxide dissolves in water. A safety match ignites and burns. A cube of ice melts to form a puddle of water. Icicles form at the edge of a rof. Water is heated and changed into steam. Milk goes sour. A chocolate bar melts in the sun. Acid on limestone produces carbon dioxide gas. Vinegar and baking soda react. A tea kettle beings to whistle. Wood and leaves rot to form humus. So, I believe that a safety match igniting and burning is a chemical change. I have many Wiki results from that, and some put physical change. I don't think it's a physical change because the fire is on the match, and once it blows out, it creates that black substace which ISN'T fire. It creates a new substance that wasn't there before. Basically, the red part of the match and the fire created that new substance. I hope this helped! Sorry if this is wrong info. *-*
Antimony trisulfide and sulfur provide the fuel for the match, which is ignited by a combination of red phosphorus (on the matchbook) and potassium perchlorate (coating the match). When friction heats the red phosphorus, some becomes white phosphorus and reacts with the perchlorate. This is sufficient to ignite the trisulfide and sulfur.

A Safety Data Sheet (SDS) contains information about the hazards of a chemical, safe handling procedures, first aid measures, and emergency response actions. It also includes information on the chemical's composition, physical and chemical properties, and regulatory information.
The reference tool you are referring to is called a Safety Data Sheet (SDS). It provides detailed information on the properties of hazardous chemicals, including their identification, physical and chemical characteristics, health effects, and safety precautions for handling and storage.
While fire, inhalation hazards, and chemical reactivity are common physical hazards, other types include electrical hazards, radiation hazards, and ergonomic hazards. These physical hazards can pose significant risks to workers' health and safety if not properly managed in the workplace. Employers should identify, assess, and control these hazards to create a safe working environment.

yes, You can not return the wood to its origonal fourm so it is a chemical change

Nurses do have hazards and they are biological, chemical, ergonomic, physical, safety, and psychological
to predict reactions and take safety plus security measures.
Each product has specific chemical and physical prperties.
MSDS contains details on the dangers associated with a chemical. It also includes information on safety procedures to use when handeling the chemical and provides emergancy response techniques.

The match head contains sulpur and an oxidising agent and they have to be struck against a special surface to make the flame. The special surface contains sand, red phosphorus and a binder. When the match is struck, friction is gererated as a form of heat and the red phosphorus turns to a white phosphorus vapour which ignites spontaneously on contact with oxygen in air. The sulphur starts to burn and ignites the match stick
Understanding the different evidences of a chemical change is crucial because it helps us identify and differentiate chemical reactions from physical changes. Recognizing signs such as color change, gas production, temperature shift, or the formation of a precipitate allows us to interpret chemical processes accurately. This knowledge is essential in various fields, including chemistry, environmental science, and materials science, as it informs safety protocols and the development of new materials or reactions. Ultimately, being familiar with these evidences enhances our ability to analyze and predict the outcomes of chemical interactions.
