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.
What does candle need from air to burn?
A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
What is the chemical change when a candle is alight?
When a candle is lit, the wax (hydrocarbons) in the candle reacts with oxygen in the air through combustion to produce carbon dioxide and water vapor. This chemical reaction releases heat and light energy, making the candle burn.
What are some reactant examples?
1. The reactants of a lit candle involve the physical properties of the chemicals oxygen, carbon and hydrogen gas. 2. H+ and OH-.
Is a lit candle Alive?
No, a lit candle is not considered alive because it does not exhibit the characteristics of living organisms such as growth, reproduction, or response to stimuli. It is a chemical reaction producing light and heat.
Using the scientific method Can a lit candle in a sealed glass die by loneliness?
No. It extinguishes from lack of oxygen.
What happens when a candle lit?
The hydrogen and the carbon dioxide mix. Candle uses oxygen and wax as fuel
Why does candle go out when lid is put on jar?
When you put a lid on a jar containing a lit candle, it cuts off the oxygen supply needed for the flame to continue burning. Without oxygen, the candle cannot sustain combustion and it goes out. Additionally, the lack of oxygen causes the build-up of carbon dioxide, which extinguishes the flame.
What does a candle need to stay lit?
Make sure you are not close to any wind!!!!!! In addition, oxygen and the wick are needed to continue the flame. If the wick runs out, or if the candle is put in an oxygen-free environment the candle will burn out.
Can you light a candle on the Moon?
moon has no atmosphere and no water on it so we cannot light a candle on moon.
What gases are given off when a candle is lit?
carbon dioxide and oxygen are given off
How long can a candle stay lit with out oxygen?
A candle will burn for a very short time without oxygen as it needs oxygen to sustain the combustion process. Once the oxygen supply is depleted, the flame will extinguish quickly.
Why does a lit candle go out when a inverted beaker is on it?
When an inverted beaker is placed over a lit candle, the flame goes out due to lack of oxygen. As the candle burns, it consumes oxygen and generates carbon dioxide and water vapor. When the beaker is placed over the candle, it creates a closed system, limiting the supply of oxygen needed for combustion, causing the flame to extinguish.
How long can a candle stay lit in a upturned jar?
The duration a candle stays lit in an upturned jar depends on factors like the size of the candle, the amount of oxygen available for it to burn, and the quality of the wick. In general, a candle may struggle to stay lit for more than a few minutes in an upturned jar due to limited airflow.
What is made by a lit candle called?
The melted wax from a lit candle is typically referred to as "candle drippings."
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.
Does a candle need oxygen to burn?
Yes, a candle needs oxygen to burn. When the wick is lit, it melts the wax, which vaporizes and combusts, reacting with oxygen in the air to produce heat and light. This process is known as combustion.
