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?
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
Give two examples of chemical changes?
1. Burning of paper 2. Vulcanizing of paper
What are freezing burning and evaporation all examples of?
Freezing, burning, and evaporation are all examples of phase changes or state changes in matter. Freezing is the transition from liquid to solid, burning typically involves a chemical reaction (combustion) that transforms substances, and evaporation is the process of a liquid turning into a gas. Each of these processes involves energy transfer and changes in the physical or chemical properties of the substances involved.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
All of the following are examples of chemical change except?
All of the following are examples of chemical change except physical changes such as melting, freezing, or dissolving. In a chemical change, the substances involved undergo a transformation that results in new chemical properties, while in a physical change, the substance remains the same at the molecular level. Examples of chemical changes include rusting, burning, and digestion.
Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
What were the examples of chemical change?
A chemical change is any kind of reaction that changes the chemical make up of a compound. Chemical changes are mostly irreversable. Such as: Burning wood Baking a cake (batter to cake stuffs) Digesting food (food to feces) etc.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
What would be ten good examples of chemical changes?
cooking lobsters wood burning baking a cake stuff like that would work
How is a chemical diffrent from a physical change?
Chemical Changes the substance and physical really dont change it as much examples of chemical: burning wood, physical: painting it Physical is basically changing color, looks,
Why are burning candle and rusting nails examples of chemical change?
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.

What are some examples of a chemical change in matter?
Examples of chemical changes in matter include burning wood (combustion), rusting of iron, cooking an egg, and fermenting grapes to make wine. These processes involve the rearrangement of atoms in the substances, resulting in the formation of new chemical compounds with different properties.
