Weighting Epsom Salts for Baths & CO? in Soda: Molecular Insight
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Learn the step-by-step process to convert moles into grams using the molecular weight of Epsom salts (MgSO?) and carbon dioxide (CO?). From bathtub to soda bottle understand the science behind the amounts
Element Classification: Rep, Trans, Inner-Trans, Noble Gases
Want To Learn More? To watch the entire video and ALL of the videos in the series:
We categorize elements into representative, transition, inner-transition, and noble gases based on their positions in the periodic table and general characteristics, without revealing specific element classifications.
Endothermic Rxn: Ba(OH)2·8H2O & NH4NO3 Heat Dynamics
Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
Protons reveal electron count in atoms. Which statement applies?
Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
Conjugate Bases of Brønsted Acids: Formulas and Descriptions
Want To Learn More? To watch the entire video and ALL of the videos in the series:
This video delves into the fundamental concept of conjugate bases in the context of the Brønsted-Lowry theory of acids and bases, explaining how when acids donate protons, they transform into their respective conjugate bases. This understanding is exemplified through the specific reactions of various compounds, illustrating how each Brønsted acid, upon proton donation, gives rise to its corresponding conjugate base.
Ionic Character Comparison: Analyzing NaBr vs. HBr and BrCl vs. FCl
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Discover the analysis of ionic character in compounds based on electronegativity differences. Learn about the contrasts between NaBr vs. HBr and BrCl vs. FCl. Grasp why NaBr and FCl showcase greater ionic character than their paired compounds.
