Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base is any substance that can accept protons. American chemist G.N. Lewis proposed a different theory. Learn about three popular scientific definitions of...
Explain the following observations: a) HCl is a stronger acid than H2S b) H3PO4 is a stronger acid than H3AsO4 c) HBrO3 is a stronger acid than HBrO2 d) H2C2O4 is a stronger acid than HC2O4- e) benzoic acid, C6H5COOH, is a stron...

In energy modeling, such as in calculating “Energy Return on Energy Invested,” a popular assumption is that all energy is substitutable for other energy. This isn’t true, unless a person accounts for all of the details of the transition, and the energy needed to make such...
