Chemistry studies how substances change through various reactions and interactions with other substances. It examines the composition, structure, properties, and changes of matter.
A decomposition reaction is a change in which one substance is broken down into two or more substances. This type of reaction is the opposite of a combination reaction, where two or more substances combine to form one product.
In science, a substance is defined as a type of matter that has a constant composition and distinct properties. Substances can be elements, compounds, or mixtures.
Physicochemical analysis is a branch of chemistry that focuses on studying the physical and chemical properties of substances. It involves analyzing various parameters such as pH, conductivity, viscosity, and thermal properties to understand the behavior of substances under different conditions and interactions. This type of analysis is commonly used in fields like environmental science, materials science, and biochemistry.
In a chemical reaction, a chemical change occurs where the chemical composition of the substances involved is altered, leading to the formation of new substances with different properties. This change involves the breaking and forming of chemical bonds.
Chemical change would cause change in physical quality or thermal value, the most observable quality is colour. It may observed a colour change of reaction but not all reaction had observable change of colour. In that case it will need to add indicator to observe a chemical change. Type of indicator may be different base on the concerned reaction. Indicator chosen may be the type that change colour due to pH or the type that react with contents of product to change colour.

It is Earth Science!! (:
cytology
geologist
what scientist studies hydrogen and oxygen
Astronomy is the science that studies celestial objects and phenomena in space. Geology is the science that studies Earth's physical structure and substance, as well as the processes that act upon it.
Geology, geography, seismology
geology is correct
a botonist studies plants...like this one @>-->--- rose!!
