CHEM 1: General Chemistry

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

Discover the contrasting processes of vaporization and condensation and their thermal nature. Understand why boiling is endothermic, absorbing heat, while condensation is exothermic, releasing heat, and how these processes impact ?H values.

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

Explore how to determine the oxidation states of Chlorine in various ions using fundamental rules in chemistry. Learn the importance of oxidation numbers in understanding chemical reactions and the art of balancing chemical equations.

Master the conversion of moles to grams with clear step-by-step guidance. Explore specific calculations for substances like carbon tetrafluoride and magnesium fluoride. Grasp the nuances of handling different units like millimoles and kilomoles in the context of substances such as carbon disulfide and sulfur trioxide
