CHEM 150: Chm 150

Discover the monatomic ions formed by potassium and iodine in this informative chemistry tutorial. Learn how to determine ion charges based on atomic properties and their positions on the periodic table.

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.

Explore the intricacies of endothermic and exothermic reactions through everyday examples. Delve into the energy dynamics of ice melting and water freezing, while emphasizing the importance of the heat change (?H) in these processes.

Explore the endothermic reaction between Ba(OH)2·8H2O and NH4NO3 observing its impact on surroundings like the freezing water. Discover why touching the beaker feels cold and learn about heat transfer in such chemical reactions. This video is an insightful demonstration of heat absorption in chemical reactions.

Explore how to determine the oxidation states of Chlorine in various ions using fundamental rules in chemistry. Learn the importance of oxidation numbers in understanding chemical reactions and the art of balancing chemical equations.

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.
