- Abstract:
How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

- Abstract:
Este módulo deriva la series de Fourier en tiempo discreto (DTFS), las cuales son un tipo de expansión de fourier para funciones periodicas y discretas en el tiempo. El módulo también da un repaso a las senosoidales complejas las cuales sirven como bases.

- Abstract:
Inorganic chemistry is a division of chemistry that studies metals, their compounds, and their reactivity. Metal atoms can be bound to other metal atoms in alloys or metal clusters, to nonmetal elements in crystalline rocks, or to small organic molecules, such as a cyclopentadienyl anion in ferrocene. These metal atoms can also be part of large biological molecules, as in the case of iron in hemoglobin (oxygen-carrier protein in the blood). Upon successful completion of this course, students will be able to: Describe nuclear charge and calculate effective nuclear charge in terms of Slater's rules; Demonstrate an understanding of trends in the periodic table; Describe the bonding between atoms in terms of valence bond theory; Describe inorganic structures by using valence shell electron pair repulsion theory; Identify the nomenclature rules of coordination compounds; Demonstrate an understanding of crystal structures, lattice energies, and different types of unit cells; Explain the electronic structure of solids, the concept of band gap energy, and how this band gap determines the electronic properties (insulator, conductor, and semiconductor) of solid materials; Describe general trends in the reactivity of elements within Groups I through VII.

- Abstract:
This course offers a rigorous treatment of linear algebra, including vector spaces, systems of linear equations, bases, linear independence, matrices, determinants, eigenvalues, inner products, quadratic forms, and canonical forms of matrices. Compared with Linear Algebra (18.06), more emphasis is placed on theory and proofs.

- Abstract:
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
