CHEM 107: General Chemistry 1

Discover how to calculate the vapor pressure of a glycerin solution when mixed with water at a specific temperature. A valuable chemistry lesson.

Understand the process of calculating formula masses for various compounds. This video breaks down the atomic masses for elements in barium bromide, dinitrogen trioxide, copper(I) sulfate, and hydrobromic acid. Master the method of summing up the masses considering atom count in each formula.

Discover the intricacies of atomic radius and its trends on the periodic table in this video. Unravel the factors influencing atomic size and explore how elements' positions on the periodic table affect their atomic radii.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

Explore the differences between physical and chemical properties in substances. Learn some fundamentals of chemistry and understand how substances interact and change.

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
