Lesson 1 Key Questions 1. Mg2+ has 10 electrons 2. Given that the half life of the radioisotope carbon -14 is 5730 years‚ it would not be useful in dating bones that are over a million years old. After 40 000 years of age less than 1% of the 14C is left in the bone and thus it is not useful for determining the exact age beyond that. 3. Hydrolysis - A chemical reaction where a chemical is broken down by a reaction with water. Hydrolysis is important for the digestion of food‚ making

How PPI (Proton Pump Inhibitors) Cause Anxiety? You might be feeling stressed and anxious at times and wondering why does it happening. I recommend you to check if you are taking proton pump inhibitors. Your doctor might have prescribed you proton pump inhibitors for your stomach related disease and you might be taking it for a long time. Yes‚ chronic use of proton pump inhibitors can show anxiety symptoms! When Do PPIs Prescribe? In digestive diseases like gastritis‚ there is increased secretion

Oxygen appears farther downfield on an NMR because of its ability to deshield protons (4.7 ppm). Nitrogen will appear around 3.9 ppm and methlylene protons which

Abstract Chemically active extraction was used to separate two unknown compounds from each other and to determine what compound class each compound belongs. The solid unknown was purified by recrystallization and its melting point range was determined to be 109-111°C. The liquid unknown was purified by simple distillation and its boiling point was determined to be 95°C. An IR spectrum was collected for each of the purified compounds; the solid was determined to be 3-toluic acid and the liquid was
