CHEM 151: Chemistry for Engineers

Explore the states of ethane hydrazine and fluoromethane at room temperature by understanding intermolecular forces. Learn about nonpolar molecules dipole-dipole interactions and the powerful influence of hydrogen bonding. Discover why hydrazine stands out as most likely to be a liquid in everyday conditions.

Learn the method to calculate the mass of a substance using its density and volume. This video demonstrates the practical application of density in determining the mass of carbon tetrachloride (CCl4) from a given volume.

This video provides insights into the concept of geometric isomerism in organic chemistry and explains why alkynes, which contain carbon-carbon triple bonds and adopt a linear structure, cannot exhibit this form of isomerism, unlike alkenes with double bonds that restrict rotation.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.

Unravel the concept of propeller twist and its role in aviation and marine propulsion. We'll delve into the science and engineering behind this intriguing phenomenon, shedding light on its applications and significance.
