What evidence of a chemical reaction might you see when burning a match?

Volatile compounds in the wood undergo combustion, or reaction with oxygen, forming H20 and CO2 gases. Because of the makeup of wood being mostly carbon-based compounds, this reaction leaves behind soot and charcoal.

What is chemical reaction when strike match?
Oxidation reaction
Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
Is the burning of paper a spontaneous reaction?
If you hold a match to the paper, then yes, the reaction is spontaneous.
Is a match is lit and Burns endothermic or exothermic reaction?
yes burning a match is an examle of very fast reaction
Is a match being lit a physical or chemical change?
A burning match is a chemical change. Burning anything is a chemical change because it forms a new substance. A physical change just alters the shape or appearance of a substance. For example, burning wood turns it into ash, a new substance, so its a chemical change. Cutting a piece of wood in half changes how it looks, but its still the same substance as before, just separated into two pieces. There are three common types of evidence of a chemical change. 1. A change in color due to a reaction with another substance. The match is reacting with fire and oxygen. 2. The production of a gas. the match gives off a smoke. 3. Formation of a precipitate or a solid that forms and saparates from a liquid mixture. burning a match does not form a precipitate, but adding acid to milk causes the proteins in the milk to undergo a chemical change that alters their structure, so they clump together. * A burning match is an example of a chemical reaction in progress. When the matchstick burns, oxygen from the air is used, mainly to form water vapor and carbon dioxide. The smoke that is generated, is a complex mixture of gases and small particles from the matchstick.
What evidence of chemical reaction would be seen when burning a match?
Burning is a chemical reaction (oxidation).
Is striking a match to a Bunsen burner a chemical reaCTION?
Striking a match initiates a chemical reacftion (burning). The proximity of the Bunsen burner has nothing to do with it.
Is burning a match a phase change?
Is burning a phase change. Explain? Ans: No because, its a chemical reaction
Would burning of matchstick be a chemical reaction?
yes it will be a chemical reaction..as the head of the match stick is being oxidized to burn. so here the oxidation reaction will take place.
Is when a match burns heat is evolved an observation law or theory?
Burning (combustion) is a chemical reaction - oxidation; this reaction is exothermic. This is a law.
Why does burning a match involve chemical reactions?
A chemical reaction suggests that something is altered(typically non-reversible)down to the chemical elements. A physical change is changing the appearance of an object(is usually reversible) A match burning changes the match down to a irreversible level
Is burning a match a physical change?
No, burning anything is a chemical change.
When a match is struck and a flame is ignited where does the energy from the fire come from and where does it go?
Burning is an exothermic chemical reaction; heat is released in the atmosphere.
What is chemical reaction when strike match?
Oxidation reaction
Is burning a wooden match physical or chemical?
Chemical, it isn't reversable.
Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
Is a burning match a example of physical energy into chemical energy?
There are many energy changes which take place when burning a match. First, kinetic or movement energy is used to scrape the match. Then, the chemical energy stored in the match becomes heat energy of the flame. I am not familiar with your use of the term physical energy, but if by this you mean kinetic energy then yes this would be an example of physical energy into chemical energy.
