pre-service chemistry teachersIn this paper we describe and evaluate a study on the use of concepts in organic chemistry while solving tasks that are designed after the concept of school-related content knowledge (SRCK). The study was designed as a mixed methods study and conducted at a ...
Overview of Chemistry Terms The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, m...

The concept of the best equation for calculating osmolality means that it has the least difference when it is measured. If such an equation is used to calculate osmolality, the normal value of osmolal gap should approach zero. But, the normal range of osmolal gap has been reported as 10 mOs...

The significance of this seemingly basic concept cannot be denied. At the foundation of almost all sciences, including biological sciences, chemistry, physiology and medicine, is cell theory. This turning point proved on an elemental level cells are similar in the way they function and reproduce ...
