REVIEW QUESTIONS How does the NaOH absorb CO27 Use the equation for Co2 reacting wth with H20 as a starting point. Draw a diagram of temperature the negative feedback pathway used by homeothermic animals to regulate body Consider the net equation for aerobic cellular respiration (ACR') Why is measuring oxygen consumption a good reliable method for measuring metabolic rate? SA/volume questions: Consider a round animal (like a fat hamster or famster) vs an animal with a flattened body gecko, croc, flounder or roadkill). Which of these would have a lower SA/vol ratio? f t were homeothermic would roquire more energy to maintain a warm body temperature? Human BMR (basal metabolic rate) can be estimated using charts of height vs weight, which yield estimates of body surface area. WHY?? What sort of units are used to measure surface area, e.g. for installing carpet in a room or reporting the size of a house? What sort of units are used to report volume? What is a 'cc"? So, if you scaled up a mouse from 4 inches long to 4 feet long (watch out puddy tat!) would it have the same SA/vol ratio?Explanation / Answer
NaOH is an alkali while carbon dioxide is a gas. Sodium hydroxide reacts with carbon dioxide to form sodium carbonate. This reaction essentially absorbs the CO2.
When carbon dioxide combines with water, it essentially forms carbonated water. The water becomes saturated with carbon dioxide. The reaction is exothermic and it gives off heat. The product formed is carbonic acid.
H2O + CO2 = H2CO3
A typical example is soda water bottle. As the bottle is opened, the pressurised CO2 escapes.
