what do you ment by combustiom=n and non-combustion substance give two example for each
Answers
Examples of Combustion Reaction:
1. Burning wood
Burning wood in a fire is an example of a combustion reaction. In the combustion reaction, the carbohydrates in wood combine with oxygen to form water and carbon dioxide. This reaction is very energetic, and it generates heat and light as it releases that energy.
2. A Lighted match
A lighted match is another example of a combustion reaction. When a match is struck, friction heats the head of the match to a temperature where the chemicals react and generate more heat than can escape into the air, and together a flame is produced. If a wind blows away the heat or the chemicals are moist and friction does not raise the appropriate temperature, the match goes out.
3. Burning coal
Burning coal qualifies as a combustion reaction because coal transforms from a solid element to a vapor during the process. Coal is comprised primarily of carbon, and when heated, reacts with oxygen in the atmosphere. In turn, it gives off large amounts of heat, making it a stable source of heat and energy.
4. Fireworks
Fireworks are smaller examples of combustion: when the end of a sparkler or firework is lit, heated chemicals react with oxygen in the atmosphere to produce heat and light that transpires as colorful displays. please mark as brainlies im trying to level up
