Chapter 15, Problem 66P

A block of zinc has an initial temperature of 94.2 degrees celcius and is immererd in 105 g of water at 21.90 degrees celcius. At thermal equilibrium, the final temperature is 25.20  degrees celcius. What is the mass of the zinc block? Cs(Zn) = 0.390 J/gxdegrees celcius Cs(H2O) = 4.18 J/gx degrees celcus

Potential Energy (kJ) 1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction. AH = -950 kJ AH = 575 kJ (i) Cl₂ (g) + Pt (s) 2C1 (g) + Pt (s) Ea = 1550 kJ (ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s) (iii) Cl (g) + CICO (g) → Cl₂CO (g) Ea = 2240 kJ Ea = 2350 kJ AH = -825 kJ 2600 2400 2200 2000 1800 1600 1400 1200 1000 a. Draw the potential energy diagram for the reaction. Label the data points for clarity. The potential energy of the reactants is 600 kJ 800 600 400 200 0 -200- -400 -600- -800- Reaction Progress

Can u help me figure out the reaction mechanisms for these, idk where to even start

Hi, I need your help with the drawing, please. I have attached the question along with my lab instructions. Please use the reaction from the lab only, as we are not allowed to use outside sources. Thank you!
