Mole Count in Elemental Samples (Zn, Ar, Ta, Li)
Want To Learn More? To watch the entire video and ALL of the videos in the series:
This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole
Decoding Compound Names: What's HNO2(aq) Called in Chemistry

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.
Synthesis, Decomposition Reactions, and Oxidation-Reduction
Want To Learn More? To watch the entire video and ALL of the videos in the series:
We explore synthesis and decomposition reactions, showcasing examples like the formation of water and its breakdown into simpler substances. We also clarify that while many of these reactions are redox reactions involving electron transfer, some synthesis and decomposition reactions may not necessarily be redox reactions, as seen in specific examples.
Unraveling Hydrocarbon Structures: Decoding Degrees of Unsaturation
