CHEM 40: Introduction to General Chemistry

Learn how to find the density of silver using weight and water displacement. A step-by-step guide to a common laboratory technique.

Discover how to find the molar mass of an unknown diprotic acid through a titration experiment with 0.1288 M NaOH. Learn step by step in this chemistry tutorial.

This video tackles the classification of boiling water as either a physical or chemical change, examining the provided options. We conclude that boiling is a physical change, as the water's chemical composition remains the same during the transition from liquid to gas.

Explore the method to determine the equilibrium constant for a reaction between iron III ions and thiocyanate ions. Learn to deduce equilibrium concentrations from initial values and reaction stoichiometry. Grasp the importance of the equilibrium constant value of 325.1 in assessing the reaction's favorability.

Discover the process of naming acids based on their anions and oxidation states. This video breaks down the correct naming of HNO2(aq) by distinguishing its anion and determining its place in the world of mineral acids.

The kinetic molecular theory of gases describes the random motion and speed distribution of gas molecules in a container, and when considering various statements about the average speeds of these molecules, it's important to understand how they behave under different conditions.
