What type of chemical reaction takes place when coal burns?
egg rolls
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 flammable a chemical or a physical change?
Something that burns or is flammable would be a chemical change.
When a candle burns what energy trasformation takes place?
Chemical energy converts into radiation plus heat. (Some of which also converts itself into [IR] radiation)
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)
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.
What type of energy changes take place when a candle burns?
Chemical energy changes into thermal energy and light energy.
What changes gives NO evidence that a chemical reaction has taken place?
Physical changes give no evidence that a chemical reaction has taken place, because no chemical reaction has taken place.
What is equation for the reaction that takes place when magnesiam burns in aiur?
Reaction that takes place when magnesium burns in air= Magnesium + Oxygen = Magnesium Oxide (magnesia)
Is a candle heated by chemical energy?
No; the process only takes place the other way around. The chemical energy in the wax is converted in an exothermic reaction (combustion) to "free" energy, which goes into the air around (heat).
What evidence tells you that phyisical porperties take place in a candle as it burns?
When a candle burns the solid wax melts to liquid and then it gets oxidized. This change of solid in to liquid is a physical activities of changing the phase of a substance.
Heat is felt when a warm object is place in your hand chemical reaction?
It's a physical reaction not a chemical reaction.
