CHEM 134: General Chemistry 1

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.

This video discusses the process of writing chemical formulas for different compounds, providing details on the types and charges of ions involved in each compound's composition. The video concludes with the chemical formulas for barium hydroxide, magnesium sulfite, calcium carbonate, ammonium sulfate, and lithium hydrogen carbonate.

Classify substances into various categories: element compound homogeneous mixture and heterogeneous mixture. This video breaks down the fundamental distinctions between pure substances and mixtures illustrating with real-world examples like urine pure water a Snickers™ bar and soil. A concise guide for understanding the essence of material classification in chemistry.

Learn the process of determining the density of a rectangular metal bar using its measurements. Understand how volume and mass play a crucial role in the calculation, and the importance of representing results with the correct number of significant figures

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.
