Rank the following compounds in order of decreasing acid strength using periodic trends.Rank the acids from strongest to weakest. If any compounds are equal in strength, please indicate.H2Se, HI, HBr, MgH2 Without consulting the table of acid-dissociation constants, match the following acids to the given Ka1 values.H2S, H2SO3, H2SO4 Ka1 values: 1.7 x 10^-7, 1.7 […]
For students, one of the hardest concepts in biochemistry to grasp is the harvesting of electrons from glucose in cellular respiration. Demonstrate how an instructor could create an assignment unique to this core content that specifically address two of the following four concepts: What is a high energy electron? What is an electron carrier […]

Write the reduction and oxidation half-reactions (without electrons). (.5 point) • ii. Balance the equations for atoms (except O and H). (.5 […]
Regulation of glycolysis and gluconeogenesis is a critical concept in biochemistry and often difficult for students to learn. This assignment allows the student to formulate a presentation on the topic and link this to the regulation of aldolase expression in various tissues of the body. Use PowerPoint 25-minute lesson teaching with a PowerPoint. Each of […]
• testing the concentration of the active ingredient( drano liquid, | Chemistry homework help Tensue123 Student outcome In this experiment we’re trying to find the concentration of the active ingredient for a households with sodium hypochlorite. The experiment carried out is a titration by using a known solution of hydrochloric acid. The equation we need to use is the CaVa=CbVb, where the C are the concentrations of the acid and base respectively, and the V are the volumes of them using in thetritation. In this experiment we have to solve for Cb, so we need to take a defined volume of sodium hypochlorite solution and add a known solution drop by drop of HCl, for example 1.00M and record how much volume of this was used in the tritation.
