**Reaction Scheme Explanation:**The image represents a chemical reaction scheme involving a substrate and a reagent, leading to a product labeled as "B."**Substrate:**- The starting material is a benzene ring with a bromine (Br) atom and a nitro (NO₂) group attached to it. Specifically, the bromine is attached to the 1-position of the benzene ring, and the nitro group is attached to the 3-position.**Reagent:**- Sodium sulfide (Na₂S) is used as the reagent in this reaction.**Process Description:**- The reaction involves a work-up step, which typically implies the purification and separation of the desired product following the initial reaction.**Product:**- The product of the reaction is labeled as "B," but the structure is not depicted in the square provided, indicating that it is yet to be determined or revealed.This type of reaction is often used in organic chemistry to study substitution reactions, where halogen groups on aromatic rings are replaced or transformed using specific reagents.

Gibbs free energy (G) is a measure of the spontaneity of a chemical reaction. It is the chemical potential for a reaction, and is minimized at equilibrium. It is defined as G=H-TS where H is enthalpy, T' is temperature, and S is entropy.

When a neutralization reaction was carried out using 100.0 mL of 0.7890M NH3 water and 100.0 mL of 0.7940M acetic acid, ΔT was found to be 4.76 °C. The specific heat of the reaction mixture was 4.104 J g-l K-1 and its density was 1.03 g mL-1. The calorimeter constant was 3.36 JK-1 a) Calculate ΔH neutralization for the reaction of NH3 and acetic acid. b) At the end of the experiment, it was discovered that the thermometer had not been calibrated. When it was calibrated, it was found that the thermometer read 0.50 °C low. What effect would this thermometer reading have on the reported DH neutralization calculated above? c) When the temperature-time data graph was reviewed, it was found that an error had been made in determining ΔT. Instead of 4.76 °C, ΔT was actually 4.70 °C. Based on this change only, calculate the correct ΔH neutralization for the reaction of NH3, and acetic acid. d) Calculate the percent error for the correct ΔH neutralization if aΔ DT of 4.76 °C had been used.…

A solution of 75.0 mL of 3.20 M HNO3 was mixed with 50.0 mL of 2.00 M Ca(OH)2 in a large Styrofoam coffee cup; the cup is fitted with a lid through which a calibrated thermometer passes. The temperature of both solutions before mixing was 20.1 °C. After the Ca(OH)2 solution is added to the coffee cup and the mixed solutions are stirred with the thermometer, the maximum temperature measured was 39.2 °C. Assume that the volumes are additive but that the density of the mixed solution is 1.10 g/mL, the specific heat of the mixed solution is 4.18 J/g•°C, and no heat is lost to the surroundings. In much the same way as you did for the previous question, calculate the enthalpy change per mole of HNO3 in the reaction. Consider that only reactants that actually react will account for the heat produced.
