How to calculate ascorbic acid by titration Indicators Indicators are used in titrations to indicate the endpoint of the titration. They typically work over only a small pH range, which must be considered when choosing what indicator to use for a particular reaction. They indicate the endpoint of...
"The redox couple NAD+/NADH has E°' = -0.45 V, while the couple O2/H2O has E°' = 0.8 V at 298K. a) Calculate the free energy change when 1 mol of NADH is oxidised by O2 at 298 K under standard conditions (biochemical). [I have calculated this to be -241kJ/mol] ...
rubredoxinPredicting the rates of spin-dependent processes characterised by nonradiative transitions between electronic states with different spin multiplicities is important for understanding the mechanisms of many photochemical and catalytic reactions. To calculate these rates, it is necessary to define the...
Answer and Explanation:1 There are a variety of ways to know when a reaction is complete. Note however that the reaction in question may dictate how one may determine whether... Learn more about this topic: Limiting Reactant | Definition, Formula & Examples ...
The evidence for this method comes from a paper [2] which tested the ability of Valence Effective Hamiltonian (VEH) to calculate redox potentials. In the paper, the onset potential and gas phase ionisations energies were observed to correlate with VEH calculated HOMO and LUMO. However, the abs...
How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? What is the relationship between a compound's stability and its enthalpy of formation? How to measure energy What's the difference between heat of reaction and heat of formation?
We next asked how it is possible that long-lived misfolded proteins are able to bypass the post-translational cellular chaperone machinery. To address this question we used coarse-grained Langevin dynamics to calculate the dissociation constant between the chaperone GroEL and three distinct conformational...
How To Determine Partial Charges Last timewe talked about how electrons are the “currency” of chemistry and every reaction is a transaction of electrons between atoms. That means that if we really want to understand a reaction, we have to understand where the electrons are (and aren’t)....
How is the process of cellular respiration compared to fermentation and photosynthesis? Calculate the net ATP produced in aerobic respiration. How does this compare to anaerobic respiration or fermentation? How many net ATPs are generated by substrate level phosphorylation in the complete br...
Zinc metal is added to hydrochloric acid (aq). Calculate the grams of zinc chloride produced if 0.238 grams of zinc react completely. You are given an unknown solution that is known to contain either Mg2+ or Cu2+ ions. The solution forms a precipitate with NaOH but not with Na2SO4...
