There are four main molecules necessary for life: proteins, lipids, carbohydrates and nucleic acids (DNA, RNA).
Nutrient
A life-sustaining substance is any substance that is essential for maintaining life and proper biological function. This can include things like water, oxygen, and essential nutrients needed for growth and metabolism. Without these substances, an organism would not be able to survive.
A mineral is an inorganic substance formed in the Earth with distinct chemical and physical properties. Minerals have a specific chemical composition and a characteristic crystal structure. They can be found in rocks and are essential components of the Earth's crust.
The change in substance that takes place around us at all times is called chemical reactions. These reactions involve the breaking and forming of chemical bonds between atoms, leading to the transformation of substances into different compounds or elements. This constant transformation is essential for life and the functioning of the natural world.
Hydrogen is the most abundant. are you asking about natural or man made chemicals? The definition of a chemical is "A substance with a distinct molecular composition that is produced by or used in a chemical process"
Nutrient
The three states of a substance essential for life on Earth are solid, liquid, and gas. These states determine how matter behaves and interacts with its environment, allowing for processes like nutrient absorption, transportation, and energy transfer within living organisms.

It is called chemical reactivity, where a substance can undergo chemical reactions and transform into different substances with new properties. This property is essential in understanding how substances interact with each other in various chemical processes.
Yes they are essential to life. If there are no chemical reaction in our body then our food are not digest and body can not get energy and if there are not chemical reaction in our environment then many usefull elements are not get etc etc
In chemical reactions, an electron donor is a substance that gives away electrons, while an electron acceptor is a substance that receives electrons. This transfer of electrons is essential for the formation of chemical bonds and the completion of reactions.
Chemical reactions occur in respiration, photosynthesis, and more life processes. Respiration and photosynthesis are both essential for life to exist.
The chemical properties of an object show what a chemical change did to that substance.

A substance is a chemical combination.
