Counting Atoms in Sulfur Dioxide: From Moles to Molecules
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Learn the method to determine the count of SO? molecules, sulfur, and oxygen atoms from a given amount of sulfur dioxide (SO?). Understand the application of Avogadro's number in translating moles to molecules. Grasp key concepts of atomic structure and counting with hands-on examples.
Structural Isomers: C4H10, C5H12, C6H14, C2H5Cl, C2H4Cl2, C2H3Cl3
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the diverse world of structural isomers! Learn how to draw structures for all constitutional isomers with various molecular formulas, including C4H10, C5H12, C6H14, C2H5Cl, C2H4Cl2, and C2H3Cl3.
Lattice Energy: Always Positive; Hydration Energy: Always Negative
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts
Lewis Structures with Atom Connections & Charges
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Learn how to create Lewis structures for various molecules and assign charges where needed. Understand the molecular connectivity and electron distribution.
Nickel(II) Nitrate Solution Composition Analysis
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this analysis, we determine the composition of a solution prepared by dissolving 12.15g of nickel(II) nitrate in 175mL of water (density 1.00 g/mL). The mass percent of nickel(II) nitrate is found to be approximately 6.50%, and the mole fraction of nickel(II) ions in the solution is calculated as 0.00672.
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.
