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

Plastic Milk Chlorofluorocarbons(CFC’S) were highly destructive to the environment which the plastic produces when burnt.This makes the ozone layer thinner that causes Global Warming. Global Warming is the changes in weather occuring on Earth that perhaphs makes our planet warmer and the reason for unpredictable weather. So scientist found out some alternative plastic which is way better because it is healthy to the environment the so-called ‘’Plastic Milk’’.It contains casein a protein found

Gas exchange is the movement of respiratory gases across a membrane. It is the delivery of oxygen to the body‚ and the elimination of carbon dioxide from the body .The reason why gas exchange takes place because oxygen is one of the most essential requirements of life‚ without which organisms on Earth would not survive. Living organisms generate energy from food through the process of respiration. This allows humans and other organisms to perform their daily tasks. Oxygen is used in mitochondria
