Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.41 2. At 40 seconds‚ pH = 7.38 3. At 60 seconds‚ pH = 7.39 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? Yes it did. It went down and then back up a little bit. 5. Was the pH level always within the “normal” range for the human body? yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No it did not Activity 2a: Hyperventilation

the Cobalt Used in Lithium-ion Batteries? In our modern world today‚ mankind’s surge in technological advances has made batteries a ubiquitous necessity in our daily lifestyles. The most popular form of battery is the lithium-ion (Li-ion) battery (Brain)‚ which is used an array of devices ranging from laptops and cellphones (Brain) to electric cars (Puiu). However‚ there is a need at the moment to develop a more sustainable and environmentally friendly lithium-ion battery. This is because the

An investigation to find out what factors affect the rate of electrolysis of a solution containing copper (II) ions. Plan It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode‚ which has a positive charge while positive copper‚ ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions‚ which have a negative

Experiment No. 1 Synthesis and Reactivity of Tert-Butyl Chloride I. Objectives : 1. To produce tert-butyl chloride from tert-butyl alcohol 2. To understand the SN1 and SN2 mechanism involved in the reaction 3. To determine the yield of percentage of t-butyl chloride II. Introduction An alkyl halide is a derivative of alkanes. Alkanes are hydrocarbons with a functional group C-C. The hydrogen atom is then replaced by a halogen (F‚ Cl‚ Br‚ I). Therefore‚ alkyl halides are compounds that have

compounds persist in the environment due to their resistance to breakdown by soil bacteria. 10 Unit The replacement of hydrogen atom(s) in a hydrocarbon‚ aliphatic or aromatic‚ by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene)‚ respectively. Haloalkanes contain halogen atom(s) attached to the sp3 hybridised carbon atom of an alkyl group whereas haloarenes contain halogen atom(s) attached to sp2 hybridised carbon atom(s) of an aryl group. Many halogen
