Why is burning a candle chemical change?
Phenomena during the candle burning:- melting- evaporation- oxydation- thermal decompositionIt is a chemical change because gas is use as a chemical. It also has friction when your trying to light it. The match is similar.Burning a candle is a chemical change because the wick is being changed into two things: ash and smoke. It is no longer a wick, and it's properties have changed.because oxygen is reacting with the flame...
Where does the wax of the candle goes?
it melts then forms back onto the candle, dries, then rebuilds the candle. It is the fuel of the candle and is consumed during the burning process.
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.

What is dust smoke or chemical fumes?
- Dust is a fine powdered solid in the atmosphere (a suspension)- Smoke is a mixture of materials (solid, liquid, gases) evolved during burning.- Chemical fume is composed from substances (solid, liquid, gases) evolved during chemical reactions.
Why burning of candle is a physical and chemical change?
CHEMICAL
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)

Mass does not change during a chemical change how about for a physical change?
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
How could you check that mass of the candle change during burning?
Put the candle on a technical balance.
Where does the wax of the candle goes?
it melts then forms back onto the candle, dries, then rebuilds the candle. It is the fuel of the candle and is consumed during the burning process.
How does burning candle affect mass differently than melting a candle?
When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce carbon dioxide and water vapor. During this process, the candle's mass decreases as some of the wax is converted into gases. On the other hand, when a candle melts, it transitions from solid to liquid state, but its mass remains unchanged as no chemical reaction occurs.
A single chemical that breaks down into other substances during chemical reactions is?
A single chemical that breaks down into other substances during chemical reactions is "decomposing".

Is ionic or covalent broken and formed in chemical reactions?
During chemical reactions bonds are broken.
What happen during metabolism?
it is broken down to fuel chemical reactions & is created by chemical reactions.

What can occur during a chemical reactions?
Weathering can be mechanical or chemical.
