Question

reread the chemical properties section: write your response to the following questions: what is a chemical property? give two examples of chemical properties. reread the physical changes section: write your response to the following questions: what is a physical change? give two examples of physical change. reread the chemical change section: write your response to the following questions: what is a chemical change? give two examples of chemical change.

Explanation:

A chemical property is a characteristic of a substance that can be observed during a chemical reaction, such as flammability or reactivity with other substances. Examples include the ability of iron to rust (react with oxygen) and the reactivity of sodium with water. A physical change is a change in the form or appearance of a substance without changing its chemical composition, like melting ice (solid - liquid change) or cutting paper. A chemical change is a process where one or more substances are transformed into new substances with different chemical properties, for example, burning wood (producing ash, carbon - dioxide, etc.) and the digestion of food.
