The polymerization process is an example.
Harmful substances in the air, water, or soil are called pollutants. These pollutants can include chemicals, toxins, heavy metals, and other harmful substances that can negatively impact human health and the environment.
A scientist who studies chemicals is called a chemist. Chemists investigate the properties, composition, and reactions of various substances to understand their behavior and applications in different fields.
Soil bacteria that break down large chemicals are known as biodegraders. These bacteria play a crucial role in breaking down complex molecules into simpler ones, making nutrients more accessible to plants and other organisms in the soil.
Under WHMIS, the chemicals in your workplace are called hazardous products. These are substances that have been deemed harmful to health or the environment and require specific labeling and safety data sheets for proper handling and use.
When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
These chemicals are called deicing substances: chlorides of sodium, calcium, magnesium, potassium.
Chemicals that act on neighboring cells are called paracrine factors or paracrine substances. These substances are released by cells to communicate with nearby cells and elicit a specific response.
These substances are called thermal insulators.
The breakdown of complex components of food into simpler substances is called digestion.
The substance (or substances) initially involved in a chemical reaction are called reactants or reagents
cytoplasm
Harmful substances in the air, water, or soil are called pollutants. These pollutants can include chemicals, toxins, heavy metals, and other harmful substances that can negatively impact human health and the environment.
Synthesis.
synthesis reaction
'Foreign' chemicals which get into the blood and provoke an immune response are called antigens.
The process of breaking a complex substance down into smaller components is called catabolism. Catabolism is the breaking down in living organisms or more complex substances into smaller ones.
When scientist creates a representation of a complex process, he is making a model. A model may be physical or conceptual in nature.
