Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
Calculating Vapor Pressure & Its Lowering: Urea in Water at 35°C
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the intriguing process of determining the vapor pressure of a urea-water solution at 35°C. Using Raoult's law we'll calculate the mole fraction of water and urea leading to the solution's vapor pressure. Learn how the solution's composition affects vapor-pressure lowering
Iron Bar: Mass Change and Rust Formation
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.
Chromium Oxides: Acidity Comparison in Water
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Compare the acidity of chromium trioxide (CrO?) and chromium (II) oxide (CrO) in water. Chromium trioxide forms strong chromic acid increasing hydronium ions, while chromium (II) oxide has weaker oxidizing properties, resulting in a less acidic solution.
