Burning candles and the rusting of nails are examples of chemical changes owing to the fact that there are chemical reactions occurring and new chemical compounds are being formed as the reaction continues.
When a candle burns, the wax and wick of the candle are undergoing combustion and (ideally) being chemically changed into carbon dioxide and water, which are two completely new chemical substances than were present in the candle. In the case of the nail, iron in the steel alloy from which the nail is made is combining with oxygen to form a chemical compound not present in the nail, namely iron oxide.
What else can I help you with?
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
Is burning candle getting shorter physical or chemical change?
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
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.
10 examples of physical change and chemical change with picture?
No pictures, but here are ten examples of physical and chemical change: Physical: melting, freezing, subliming, condensing, deposition, vaporizing, crushing, bending, tearing, mixing in a heterogeneous mixture. Chemical: combustion, rusting, baking, electroplating, yeast, acid and base neutralization, baking soda and vinegar, chemical battery, metabolism.
Is candle burning physical change?
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
Why burning candle is chemical change?
It is a chemical change because the burning thread is combusted. The combustion is an oxidation reaction. Most importantly, it is a chemical change because after burning, the chemical properties of the thread is changed entirely!
Why are burning candles and rusting examples of chemical changes?

What is a chemical reaction melting ice rubbing a marker on paper burning a candle rusting iron?
Melting ice is a physical change as it involves a change in state from solid to liquid without changing the chemical composition. Rubbing a marker on paper involves a physical process of transferring ink from the marker to the paper, without any new chemical reactions occurring. Burning a candle is a combustion reaction where the wax reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. Rusting iron is a chemical process where iron reacts with oxygen and moisture in the air to form iron oxide.
Is burning candle getting shorter physical or chemical change?
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
What are 3 examples of energy transformations for a burning candle?
Chemical energy in the wax of the candle is transformed into heat and light energy through the process of combustion. The heat energy produced from the burning candle can be transferred to its surroundings, leading to an increase in the thermal energy of the surrounding air and objects. The light energy emitted by the candle can be absorbed and transformed into thermal energy or chemical energy by objects or materials in its vicinity.
What is burning candle it is physically Chang or chamically?
Burning a candle involves a chemical change, as the wax is being oxidized by the oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process is irreversible and results in the formation of new substances, which is characteristic of a chemical change.
Are there any examples of metonymy in love?
Love is a burning candle
What are non examples of physical change?
Any idea is a non example of physical change.
How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
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.
