CHEM 101: Intro to Chemistry - 90496 - Ch 101 - 01

This video discusses the process of writing chemical formulas for different compounds, providing details on the types and charges of ions involved in each compound's composition. The video concludes with the chemical formulas for barium hydroxide, magnesium sulfite, calcium carbonate, ammonium sulfate, and lithium hydrogen carbonate.

In this video we explore the process of calculating the weight percent of barium potassium and chlorine in a mixed sample of barium chloride dihydrate and potassium chloride. Through a step-by-step approach we examine the changes in sample weight after heating to 160°C breaking down the calculations for each elemental content.

Learn how to determine the weight of white gas carried by a backpacker using its density. A valuable skill for hikers and campers.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

Delve into the journey of scientific ideas as we discuss how a hypothesis can evolve into a theory, and whether a theory can ever become a law. Uncover the distinctions and connections between these fundamental elements of scientific understanding in this illuminating video.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.
