Chemistry and biochemistry are two closely related fields that explore the composition and behavior of matter, but they do so with different focal points. Chemistry studies substances, their properties, and how they interact at the atomic and molecular levels. Biochemistry, on the other hand, applies chemistry to understand the molecular processes within living organisms, including…

Chemistry and biology are two essential branches of science that study the natural world, each with its own unique approach. Chemistry focuses on the composition, structure, and interactions of matter at the atomic and molecular levels, while biology explores living organisms, their functions, and how they interact with their environment. Despite their differences, these fields…

An evaporating dish is a shallow, heat-resistant ceramic or glass vessel used in laboratories to evaporate solvents and concentrate solutions. It is commonly used in crystallization, drying samples, and removing excess liquid from chemical mixtures. The dish’s wide, open surface area allows for faster evaporation, while its high heat resistance enables it to withstand direct…

A pressure-equalizing dropping funnel (also called a pressure-equalizing addition funnel) is a type of laboratory glassware used for the controlled addition of liquids to a reaction mixture while maintaining equal pressure between the funnel and the reaction vessel. It consists of a graduated glass funnel, which allows for precise measurement and controlled addition of liquids…

In a laboratory setting, handling hot, hazardous, or delicate materials requires precision and care. Chemistry tongs are essential tools designed to safely grip, transfer, and manipulate various objects, from heated glassware to small chemical samples. These tongs come in different shapes and sizes, each suited for specific tasks to ensure both efficiency and safety in…

Chemistry and physics are two fundamental branches of science that explore the natural world, each with a distinct perspective. Chemistry focuses on the properties, composition, and reactions of matter, while physics seeks to understand the fundamental laws governing the behavior of matter and energy in the universe. Despite their differences, these fields are deeply interconnected…

When studying other scientific disciplines, such as biology, physics, geology, agriculture, engineering, medicine, and so forth, you will notice that chemistry is an integral part of your curriculum. This is because chemistry is fundamental to the understanding of these disciplines. Chemistry serves as a bridge between other scientific disciplines and that’s why it is often…

1. Problem # 1 Chlorine -35 forms 75% of the total mass of chlorine and chlorine-37 forms 25%. Calculate the relative atomic mass of chlorine. Solution Consider a sample containing about 100 atoms of chlorine: 75 atoms will each have a mass of 35, which means that their total mass will be 35 X 75…
