ChemistryCalculating delta H of reaction using bond energies? Hi, I have been stuck for hours, i do not understand how i am supposed to use bond energy values for this question like it asks when bond energy values are for molecules in the gas state. The first molecule reactant is a liqu...
To solve the problem of identifying the reaction for which ΔH ≠ΔE, we need to understand the relationship between enthalpy (ΔH) and internal energy (ΔE) in the context of chemical reactions. Here’s a step-by-step breakdown of the solution:<

The invention comprises compounds of formula wherein R is Me or formyl; R 1 and R 2 are each H, acetyl or C 1-6 alkyl or together form isopro pylidene; and R 3 is H, acetyl or C 1-6 alkyl; provided that at least one of R 1 , R 2 and R 3 is C 1-6 alkyl. ...
Some applications require that the reaction time to an input signal exceeding the thresholds, be faster than the main conversion speed. The monitoring of the thresholds for the main conversion itself is usually more precise but slower. Short circuit detector T...
This reaction will need reagent Et3SiH and solvent CH2Cl2 with reaction time of 30 min. The yield is about 82%. You can still convert the following datas into molecular structure: (1)Canonical SMILES: CC1CCCC(=O)O1 (2)InChI: InChI=1S/C6H10O2/c1-5-3-2-4-6(7)8-5/h5H,2-4H2,1...
To obtain viral load from cycle threshold (Ct) values, the conversion formula was used10: $${\log }_{10}\left({{{\rm{viral\; load}}}\left[{{{\rm{copies}}}/{{{\rm{mL}}}\right]\right)=-0.32\times {C}_{t}{{{\rm{values}}}\left[{{{\rm{cycles}}}\right]+14.11$$ (1...
The entropy change of a specific reaction can be figured out with the help of absolute entropies of each substance in that reaction. The formula specified below is employed for working out {eq}{\rm \Delta S_{rxn}^o} {/eq}in this problem {eq}{\r...
