CHEM 110: General Chemistry 110

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.

This video delves into the fascinating world of energy storage in animals and plants, offering insights into why fats are the primary energy storage compound in animals (except muscles) and why plants opt for alternative strategies instead of using fats and oils.

Discover Lewis structures for various molecular formulas, including N2, HCN, CO2, C3H6, and more. Explore their chemical bonding and structural arrangements.

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.

This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole

Unravel the reaction of chromium and oxygen forming chromium(III) oxide. Examine different scenarios to determine the limiting reactant using stoichiometric ratios. Understand how to predict product amounts through these calculations.
