If a candle burning example of?
Candle burning is the process called oxidation. This is, it's the reaction that takes place when a gaseous material reacts with oxygen, the wax needs to change to gaseous state for the reaction to take place.
Is candle burning a reversible change prove it?
Not reversable, If you put a burned candle in a cold dark place, it does not become whole again.
When boiling take place is the phase change a chemical or physical change?
Boiling is a physical change.
What change in matter can be reversed?
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
Is it true when a physical change that takes new substances are formed?
It is false. When a physical change takes place, the colors, texture, brittleness will change.
Is a candle burning chemical change?
Yes, burning a candle is a chemical change. New chemical compounds are being formed as the reaction continues. The paraffin in the candle is a hydrocarbon chain, and it is "breaking down" chemically using oxygen from the air to form (idealy) carbon dioxide and water. But there are also physical changes that take place at the same time. Phenomena during the candle burning: - melting (physical phenomenon) - evaporation (may be considered a chemical but also a physical phenomenon) - oxydation - reaction with oxygen, burning (chemical phenomenon) - thermal decomposition (chemical phenomenon)
Why burning of candle is a physical and chemical change?
CHEMICAL
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.

When candle is broken in half does this indicate that only a physical change is taking place?
Yes.That's a physical change only.
Is candle burning a reversible change prove it?
Not reversable, If you put a burned candle in a cold dark place, it does not become whole again.
What evidence is there when a candle burns that a physical change takes place?
The was becomes liquid and drips down the rest of the candle.
How can you tell that the burning of a candle causes both physical and chemical change?
By observation: 1. A flame shows that heat is being generated, indicating a chemical change taking place. 2. A physical change would be the solid wax changing to liquid under the flame.
What physical change is shown taking place in burning wood?
chemical change.
When you place a glass rod over a burning candle it gets black what change happens to the glass rod as the candle burns?
Unless the glass rod is heated to very high temperatures, nothing will happen except that it will be covered soot from the incomplete burning of the candle.
Is burning a candle wick a chemical change?
Candle wax burning is a chemical change. During the process of burning, the wax undergoes a chemical reaction with oxygen from the air, resulting in the formation of new substances and the release of energy in the form of heat and light. This to due to the fact that candle waxes is a hydrocarbon compound , namely, it is the paraffin wax. Therefore, to be more specific, the combustion equation can be written as follows: Paraffin Wax (C25H52) + Oxygen (O2) → Carbon Dioxide (CO2) + Water Vapor (H2O) If you wish to learn more about candles, please check out ohcans candles. We have blogs dedicated to candle making.
What are facts about candle making?
Candle making facts are people enjoy the process of personalizing the candle. You must be neat about it. And there is a certain way to place the wick for best burning.
