Chemistry is the study of the properties, composition, and structure of substances, and the transformations they undergo. It also deals with the energy exchanges in these processes. As "The Central Science", chemistry interrelates with numerous other scientific disciplines.
Chemistry, often referred to as "The Central Science", is a branch of science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. It plays a vital role in multiple disciplines such as biology, medicine and environmental science. It allows us to understand the makeup of substances, from the atomic level to complex molecules, and how they interact through chemical reactions.
One example of a branch of Chemistry is thermochemistry, which focuses on relationships between heat, work, and other types of energy in physical and chemical processes. Dalton's atomic theory, investigating quantitative and qualitative aspects of chemistry, also developed the concept of atomic mass units, allowing for the calculation of formula mass and the quantitative description of substances.

how is the amount of neutrons determined?
Respuesta:
2 m
Explicación:
Paso 1: Información provista
Paso 2: Calcular la concentración de la solución final
Queremos perparar una concentración diluida a partir de una concentrada. Podemos calcular la concentración de la solución diluida usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 4 m × 100 mL / 200 mL = 2 m
