stoichiometry is the relationship between the quantities of reactants and products before, during, and following chemical reactions.
Chemistry has been termed by the physicist as the messy part of physics, but this is not the reason why the physicists should be allowed to make a mess of
To enhance student performance in practical exams, educators should ensure clear communication, provide hands-on practice, create interactive learning environments, give timely feedback, and encourage collaboration, self-assessment, and time management.
Hardness refers to a material's resistance to indentation, scratching, or abrasion. It is a measure of how easily a material can be scratched or deformed by an external force.
A reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.
The reactivity series, also known as the activity series, is a list of metals arranged in order of their reactivity. In this series, metals are ranked from the most reactive
In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and
The enthalpy of a chemical reaction, often denoted as ΔH (delta H), is a measure of the heat energy absorbed or released during a chemical reaction at constant pressure. Enthalpy
These questions should stimulate in-depth discussions about polymerization, its mechanisms, applications, and implications in various fields.
Brownian motion, or pedesis (from Ancient Greek: πήδησις /pɛ̌ːdɛːsis/ "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas).[2] This pattern of motion typically
Which metal would be suitable for all of the following uses? • making aircraft bodies • making food containers • making overhead power cables
Physical chemistry and organic chemistry are two distinct subfields within the broader discipline of chemistry, and they focus on different aspects of the subject. Here are the key differences between
Acids and bases are two distinct types of chemical substances with contrasting properties. Here are the main differences between acids and bases:
noble gas, any of the seven chemical elements that make up Group 8 (VIII) of the periodic table.

In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the
quizzes play a crucial role in assessing student understanding, promoting active learning, providing feedback, enhancing motivation, and preparing students for larger assessments
“Wherever we look, the work of the chemist has raised the level of our civilization and has increased the productive capacity of our nation.” ― Calvin Coolidge
In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom.
