What identifies a chemical change has taken place?
Signs that a chemical change has taken place include the formation of a gas, the formation of a precipitate, a change in temperature, and a change in color.
How can you know this is a chemical reaction?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
Explain what a chemical change is?
A chemical change is when a substance undergoes a transformation that results in the formation of one or more new substances with different chemical properties. This typically involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include rusting of iron and burning of wood.
Is limestone cave formation chemical or mechanical weathering?

When compost pit turns into mulch is that a chemical change?
The answer would be Yes.The physical characteristics of all compost ingredients under go a change by way of a chemical reaction. Carbon, Nitrogen, Oxygen, and Moisture (Water), are 4 key ingredients that composting organisms require for this reaction to work.
Is the rotting of compost a chemical reaction?
Yes, the rotting of compost is a chemical reaction. It involves the breakdown of organic matter by microorganisms through processes such as decomposition, fermentation, and oxidation, which result in the release of nutrients and the formation of humus.

Is formation of table salt a physical or chemical change?
Formation of NaCl from chlorine and sodium is a chemical process.
What are the sings of chemical reactions?
The signs of a chemical reaction include change in temperature, change in color, formation of gas, formation of a precipitate, disappearance of a solid, formation of a new odor.
How can you identify that a change is chemical?
A change is chemical if the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Look for indicators such as color change, gas production, temperature change, or formation of a precipitate to help identify a chemical change.
