MeO 3. Propose a suitable mechanism for the following reaction HO-N interm H2SO4 CH3CN in CN

Balance the reactions. A hint is provided to help you decide if the reaction will proceed as written, ie from left to right. Do not leave any fractions. 1. a) Balance Al₂O3 → Al + 0₂ b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) 2. a) Balance HNO3 + AI → b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: aluminum is a reactive metal, and a gas escapes) C7H14 + 0₂ 3. a) Balance, leave no fractions b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) H2(g) + AI(NO3)3 → CO₂ + H₂O

5. You discover a new cysteine protease similar to papain. Cysteine proteases are proteolytic enzymes that utilize a cysteine residue in the active site for the nucleophilic attack of a peptide bond, while a second residue acts as a base for proton abstraction in the reaction (acid base catalysis). In this novel enzyme the pKa of the cysteine residue is significantly lowered by the active site environment to pKa=4. a. Knowing that the protease shows highest activity between pH 4-6, what could be the identity of the base residue acting as a in the reaction? Explain and write the expected mechanism for the reaction.

WHich arrow represents the ΔG for the catalyzed reaction and which arrow represnts the activation energry for uncatalyzed reaction

please help me identify these huhu thank you

Select the incorrect statement. With regards to free energy ΔG of the reaction below E+S ⇌ ES   Negative ΔG mean the reaction toward is facourable More negative value of ΔG indicates stronger binding to S to E It is possible to compute disassociation constant from the ΔG value alone It is possible to calculate the term ( ΔH – T ΔS) from the value of ΔGalone ΔG = 0 indicates (ES)/(E)(S) =1 None of the above
