When burning a piece of wood what evidence is there to show that a chemical reaction had taken place?
smoke
What else can I help you with?
How can you tell that a burning piece of wood is chemical change?
When a burning piece of wood undergoes chemical change, it reacts with oxygen in the air to produce new substances such as ash, smoke, and gases. The change is irreversible, and the properties of the wood are altered as it transforms into new compounds. Additionally, heat and light are often produced as a result of the chemical reaction, further indicating a chemical change.
If you burn a piece of wood it becomes a different substance. What type of property is this?
This is a chemical property, as the burning of wood involves a chemical reaction that transforms the wood into ash, gases, and other byproducts, resulting in a new substance.
What is law of consevation of mass with experiment?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; it is simply rearranged. An experiment to demonstrate this is burning a piece of paper: the mass of the paper before burning will be the same as the mass of the ashes, smoke, and gases produced after burning. This experiment confirms that the total mass before and after the reaction remains constant.
Name a chemical change?

What is a piece of paper is set on fire is this chemical or physical change?
When a piece of paper is set on fire, it undergoes a chemical change. The act of burning involves a chemical reaction where the paper combines with oxygen in the air to produce new substances like ash, carbon dioxide, and water vapor.
Which action forms a different chemical substance?
Any chemical reaction produce a new substance.

What is and example of a chemical reaction melting water burning a piece of wood dissolving salt in water or breaking a tree branch?
An example of a chemical reaction is burning a piece of wood. During this process, wood reacts with oxygen in the air to produce carbon dioxide, water vapor, and ash, resulting in a chemical change. In contrast, melting water, dissolving salt in water, and breaking a tree branch are physical changes, not chemical reactions, as they do not alter the chemical composition of the substances involved.
Why a piece of wood is the example of the chemical reaction?
A piece of wood by itself is not an example of a chemical reaction. However, when the wood is burned, it chemically combines with oxygen in the air, producing mostly water and carbon dioxide. Because new chemical substances are created in this combustion reaction, the burning of wood is a good example of a chemical reaction.
When a piece of paper burns is it a physical or a chemical change?
Burning is a chemical change.

Is burning a piece of paper chemical change or physical change?
Cheimical change
How do you usually release the chemical energy stored within a piece of wood?
By burning it.
A different chemical substance is formed when a piece of cloth is cut cup breaks candle burns or a piece of chalk breaks?
The candle burning is a chemical process.
