What is the chemical change called in a lit candle?
The chemical change in a lit candle is called combustion. Combustion is a rapid chemical reaction between oxygen in the air and the fuel (in this case, the wax in the candle) that produces heat, light, and carbon dioxide.
when a candle is lit it undergoes a chemical change?
That is correct, a candle (or the material of which it is composed, which is usually paraffin) undergoes a chemical change when it burns.
Is an apple that is cut a physical or a chemical change?
It is a physical change because while the apple is cut into smaller pieces, it is still composed of the same materials. If you lit the apple on fire, that would result in a chemical change.
Is crumbling paper a chemical change?
Physical. You're not doing anything to alter the chemical structure of the paper. If you soaked it in ethanol and lit it on fire before crumpling it, that would be a chemical change.
What chemical reactions happen when a firework is lit?
combustion...

How is lighting a match a chemical change?
When a match is lit, the chemicals in the match head undergo a chemical reaction resulting in the production of heat, light, and new chemical compounds like carbon dioxide and water vapor. This transformation of the chemical composition of the match represents a chemical change.
When the candle was lit a pool of liquid wax formed in the area around the wick and then spilled over the side and solidified does this observation reefer to a physicalor a chemical change?
This observation refers to a physical change. The melting and solidifying of the wax is a reversible process that does not change the chemical composition of the wax molecules.

Is a lit sparkler physical or chemical?
A lit sparkler involves both physical and chemical processes. The sparkler itself is a physical object, but when ignited, a chemical reaction occurs as the oxidizers and fuel in the sparkler's composition burn, producing heat, light, and various gases. This combination of physical presence and chemical reaction defines the nature of a lit sparkler.
What type of energy is in a lit candle?
Chemical energy is converted to light and thermal energy.
Is lit flourescent light bulb a chemical change?
Hmm, well lets see, if it's chemical there's no going back right? You cant make it into what it was, so if a flashbulb goes off, it like, explodes, and you need a new one because you can't use a broken bulb...(duh)... so i guess it's a chemical change . (Sorry for not getting to the point quickly ^-^)
What type of energy is a match before it is lit?
chemical energy
How fast is Mach 0.85?
Mach number is dependent on a number of factors. Factors such as air density or altitude will change the Mach number. At approximatively 45 000 ft Mach 0.85 =289.2361 m/s = 1041.25 km/h = 647.0028 mph
