CHEM 100: People and Chemistry

Explore the calculations for mole fractions, partial pressures, and total pressure in a 22.4 dm³ vessel with H? and N? at 273.15 K.

Discover the difference between strong and weak electrolytes by understanding their ionization in water. Using nitrous acid and nitric acid as examples, this video provides chemical equations that visually distinguish the ionization behavior of these electrolytes.

Join us in this enlightening video where we unravel the world of chemistry. We'll examine a series of options to identify elements, compounds, and mixtures. Explore the fascinating world of matter and discover how to distinguish these fundamental concepts. Whether you're a student or simply curious about the world of chemistry, this video will help you sharpen your understanding of the building blocks of matter.

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.
