CHEM 1050: Chemistry for Citizens

Discover the balanced chemical equation for photosynthesis, where CO? and H?O produce glucose and O?. Uncover the step-by-step breakdown of the equation, ensuring atom balance. Grasp a clear understanding of this vital process in plant biology.

This video explains the importance of the number of valence electrons in an element's chemical behavior and demonstrates how to determine the valence electrons for potassium, calcium, and aluminum based on their positions in the periodic table. Valence electrons dictate an element's reactivity with other elements, making this knowledge essential for understanding chemical reactions.

Discover the incredible speed of light as it zips 7.5 times around Earth in just a second! Marvel at its daily and yearly travels, equating to billions and trillions of kilometers. Dive deeper into the concept of a 'light year' and its significance in astronomical measurements.

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

This video focuses on unit conversions and the practical use of conversion factors to translate quantities between different units. It provides clear examples of converting 70 kilograms to pounds, translating 14 billion years into seconds, changing the height of a basketball player from feet and inches to meters, and converting cubic meters to liters, illustrating the importance of this skill in various scientific and everyday scenarios.
