CHEM 1211: Principles of Chemistry I

Explore the groundbreaking moment in 1828 when Wöhler synthesized urea, the first organic compound. Join us in this video as we trace the profound impact of this achievement on the field of biochemistry and its significance in unraveling the mysteries of life's complex chemistry.

Discover how to calculate the number of moles of hydrogen in different chemical samples, including H?O, NH?, N?H?, and C??H??.

Unpack the difference between quantitative and non-quantitative observations. Examples include a person's weight on the Moon and the depth a hand pump can reach. Learn why precise measurements are crucial in scientific studies.

Join us in this video as we dive into the intricacies of calculating the net ATP yield from oleic acid (18:1 ??). We'll provide a step-by-step guide and offer helpful hints to ensure an accurate calculation, including a critical step that bypasses acyl-CoA dehydrogenase.

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.

Understand gas stoichiometry by exploring the Ideal Gas Law, which integrates key laws like Gay-Lussac's, Charles's, Avogadro's, and Boyle's. Discover how this equation helps determine relationships between gas volumes and moles in reactions.
