What is the difference between a natural and synthetic material?

Back

Natural material is made directly from nature and synthetic material is made from chemicals.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is the general formula for a decomposition reaction?

Back

AB --> A + B.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex substance.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds.
