What are the examples of chemical?
Examples of chemicals include the chemical elements, such as zinc, helium, and oxygen; compounds made from elements including water, carbon dioxide, and salt; and more complex materials like your computer, air, rain, a chicken, a car, etc..
What are 4 examples of chemical properties?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2).
What is an example of both a physical and chemical change?
Melting and burning of candle wax is an example of both physical and chemical changes. Answer: Burning of wood is a example of both physical and chemical change. When wood is burnt the moisture present in it turns to vapour ,it is a physical change while it burns and generate CO2 is a chemical change.
What are 2 differences between physical and chemical changes?
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
What are three examples of physical changes?

What is a chemical change give an example?
Burning, cooking, rusting, and rotting are examples of chemical changes. 2. What is called chemical change? Ans: A chemical transition, also known as a chemical reaction, is a process that transforms one or more substances into one or more new and different substances.
What are some examples of chemical reactions?

What are 3 differences between physical and chemical changes?
A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. … Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
