Design Lab Experiment: How would an increase in the atomic radii of the metals in period 4 affect the time it takes for a metal to react with HCl. Hypothesis: If Hydrochloric Acid is dropped on all of the metals in period 4‚ then the elements with the largest atomic radii will react faster with Hydrochloric Acid because atoms with bigger atomic radii are

It is a very variable protein‚ forming the basis of many connective and support tissues. It is a fibrous structural protein‚ with a distinctive structure. In fact‚ collagen makes up about one-third of the total body weight. Its name is derived from the French word for glue. Collagen fibers‚ which resemble microscopic

Abstract In the asymmetric synthesis of (S)-Ibuprofen‚ the compound is synthesized in nonracemic form directly from an achiral precursor. First‚ racemic ibuprofen was converted to aN achiral ketene via the acid chloride by adding thionyl chloride followed by triethylamine. Then‚ ketene was reacted with a chiral and nonracemic (S)-ethyl lactate produces a mixture of diasteromeric esters of ibuprofen derivatives where (S) configuration is predominantly. Finally‚ hydrolysis of the ester then provides

Human Demography: The study of age-structured populations Lab Preparation: Read the lab and be on time. There will be a quiz. Also‚ we’ll be riding a bus to the field location. If you want to join us for lab‚ don’t miss the bus! Bring your lab manual‚ a hard notebook or clipboard‚ paper and charcoal (for rubbings) and wear warm‚ possibly waterproof clothes. We’ll be outside for a good portion of the lab regardless of the weather. Background: Demography Demography is the descriptive study

Lab #3 Atomic Structure & Classification of Matter Objectives Write the correct symbols or names of some elements. Describe some physical properties of the elements you observe. Categorize an element as a metal or nonmetal from its physical properties. Given the complete symbol of an atom‚ determine its mass number‚ and the number of protons‚ neutrons‚ and electrons. To identify and classify different types of matter. Background Primary substances‚ called elements‚

Acidic vs. Alkaline Introduction: Potential of hydrogen‚ or pH‚ is a scale used to express the acidity or alkalinity of a solution. The scale ranges from 0 to 14‚ below seven represents acidity‚ seven is neutral‚ and more than seven is basic. Acid-base indicators show whether the solution is acidic or alkaline. They do this by reacting with the solution‚ seen as a color change‚ as the concentration of hydrogen (H+) or hydroxide (OH-) ions changes in an aqueous solution. Different indicators
