Use Table 8.3 to obtain H for the following chemical equations: (a) Zn(s)+2 H+(aq)Zn2+(aq)+H2(g) (b) 2H2S(g)+3O2(g)2SO2(g)+2H2O(g) (c) 3Ni(s)+2NO3(aq)+8H+(aq)3Ni2+(aq)+2NO(g)+4H2O(l)

Please Don't used hend raiting and don't use Ai solution

help  please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working!

Use the information below to answer questions 1- 3. PCI,(g) 2 PCI;(g) + Cl2(8) PCI,(g) decomposes into PCI,(g) and Cl,(8) according to the equation above. A pure sample of PCI,(g) is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCI5(g) is 1.00 atm. The temperature is held constant until the PCI,(g) reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system. PCI5 Potal = 1.00 atm PCI5, PCI3, and CI, Prstal = 1.40 atm Figure 1: Initial Figure 2: Equilibrium As the reaction progresses toward equilibrium, the rate of the forward reaction (A) increases until it becomes the same as the reverse reaction rate at equilibrium (B) stays constant before and after equilibrium is reached (C) decreases to become a constant nonzero rate at equilibrium (D) decreases to become zero at equilibrium If the decomposition reaction were to go to completion, the total pressure in the container would be (A) 1.4…

Conside 'pothetical chemical reaction: A+B C+D (In this equation A, B, C and D stand for some unknown chemical formulas.) Here is an energy diagram for the reaction: energy (kJ/mol) 400 300 200. 100- 0 A + B C + D reaction coordinate Use the energy diagram to answer these questions. What is the heat of reaction? Is the reaction exothermic or endothermic? Can you determine the activation energy? C+D→ A+B Can you determine the activation energy of the reverse reaction? kJ/mol Exothermic Endothermic Neither Yes, it's kJ/mol No. Yes, it's kJ/mol No.
