Module 1: Lesson 5 ASSIGNMENT (12 marks) Lesson 5 Assignment Part 1: Molar Heat Calculations (3 marks) 1. Calculate the molar enthalpy of the NaOH(aq) using the data obtained from this experiment. Show all your work. Answer: Specific heat capacity: 4.19 J/g∙°C 50.0 ml of 1.0 mol/L NAOH Initial temperature: 23.9 °C Final temperature: 32.9 °C Change in temperature: 9 °C Q = mc∆t = (80g)(4.19 J/g∙°C)(9°C) = 3016.8 J or 3.0168 kJ ∆rH = n∆rHm 3.0168 kJ = (0.05

Water is a very valuable in our daily lives. Water is composed of two kinds of gases as we know‚ Oxygen and Hydrogen. There are two kinds of water‚ which is‚ sweet and saline. But water is originally sweet. It only becomes salty when it comes in contact with the mineral salts while passing and flowing through the land. The water which is of the sea‚ ocean and lakes are salty/saline. Water that has a very important role for all living creatures on our planet has been decreasing day by day. Global

laboratory was performed to find the temperature change‚ heat of reaction‚ and enthalpy change for neutralization reactions. The temperature change was found by subtracting the initial temperature from the final temperature obtained. Heat of reaction is negative heat of solution. Heat of solution was found by using the formula qsolution = mCsΔT (m= mass; Cs= 4.184 J/g°C; and ΔT = change in temperature). The enthalpy change was found by dividing the heat of reaction by the number of moles of H2O formed.

1. Shell and Tube Heat Exchanger – Working Principle The shell and tube heat exchanger comprises of two major things as its name state "Shell and Tube". The shell is a major vassel with quantities of tube inside it (Jalmood‚ n.d). Shell and tube heat exchangers are helpful for pressurized application. Heat is exchanged between the liquid in the tubes and the liquid inside the shell. Configuration of the tube pack is such that‚ all the section sides of the tube could be joined with a typical header
