What are the shapes and designations of the f orbitals? The exotic, complex f orbital shapes are rarely shown in textbooks. General (and organic) chemistry traditionally focuses on the lighter elements, but the forbltals aren’t occupied in the ground state

AP Chemistry Kinetics Lab Abstract: The purpose of this lab is to learn how to write law expressions, determine orders by graphs, and calculate rate constants. By determining the number of drops of sodium hypochlorite necessary to make a diluted

Balancing equations is a fundamental skill in Chemistry. Solving a system of linear equations is a fundamental skill in Algebra. Remarkably, these two field specialties are intrinsically and inherently linked. 2 + 02 —-> H20A. This is not a difficult

Follow all directions and review with your instructor the safety recautions needed to conduct the experiment safely before you begin. Only materials and equipment authorized by your instructor should be used. 3. Everyone should be alert and proceed with caution

Organic compound From Wikipedia, the free encyclopedia Jump to: navigation, search Methane is one of the simplest organic compoundsAn organic compound is any member of a large class of chemical compounds whose molecules contain carbon. For historical reasons discussed below,

Purity and purifications of solids using melting points. Tatyana Aleksandrova CHE 337, Section 001 Department of Chemistry Portland State University, Portland, OR ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?

This experiment focuses on the concept of electrophilic aromatic substitution, which is a type of benzene reaction. This reaction consists usually of benzene and an electrophile. The role of the nucleophile is played by the double bond on the benzene

A suspected white powder was seized from the crime scene and sent to the laboratory for analysis. Presumptive test was firstly used in order to find out if it was a positive drug, in order to follow a further analysis.

Iron is much harder than bronze. * Modern Age (1 CE – Present) – main metals are iron, aluminium and steel, which were used for pipes, buildings, transport and electrical cables. This is the age where technology of iron and

Introduction: Considering the beneficial properties of plants, not only to us, but the environment as well, it is important to understand the nature of Allelopathy and how it affects plant ecology. According to the Topics in Biology Laboratory Manuel, allelopathy

Food Chemistry What is food chemistry? Food chemistry is the application of the actual science that goes into the production, development, and actual creation of the foods we frequently consume. In reality, much more thought as well as actual science

Observe the solubility in hot water. c. Tear off approximately 1/2-cm pieces of both red and blue litmus paper. d. Allow the solution to cool, and using the glass stirring rod, transfer a drop of the solution onto a piece

When no KHC4H4O6 dissolves, the concentrations of K+(aq) and HC4H4O6-(aq) will not increase further and any additional KHC4H4O6 added after this point will remain as a solid. At this point, the solution is said to be saturated. The rates at

I determined that my hypothesis was correct. The glass I chose to add the pure cane sugar did grow much more crystals at a more rapid pace. The purpose of my experiment is to grow a large amount of crystals

Crystals are formed when atoms line up in patterns and solidify. There are crystals everywhere — in the form of salt, sugar, sand, diamonds, quartz, and many more! To make crystals, you need to make a very special kind of

In this reaction, molecules of benzophenone was brought to n((* triplet state where it possibly abstracted hydrogen from isopropyl alcohol and through subsequent reactions of radicals it formed two diphenyl ketyl radical which dimerized into benzopinacol. Subsequently, mixture of synthesized

Diffusion Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration, water will move across the membrane in response to this concentration. While conducting

The higher the enzyme concentration, the higher the absorbance value. Different molecules absorb different wavelengths of light. For this experiment, the spectrophotometer is set at 420nm, so that we can obtain the best absorbance results. ONPG >galactose+ o-Nitrophenol A catalyst

The first part concentrated on the placing potato cylinders in different sucrose concentrations for a period of time. This part was conducted to see if the potato cylinders would gain weight or lose weight because of osmosis. The second part

Measure the length and width of a second raisin and place it in one of the salt water containers. Measure the length and width of a grape and place it in the second of the plain water containers. Measure the

The objective of this lab was to show how stoichiometry is applied to a specific chemical reaction. Stoichiometry is pretty much the math behind chemistry. Doing stoichiometry can calculate masses, moles, and percents with a chemical equation. The use of

pADVENTURES of an Atom By: Nicole Zemaitis Atom-Smallest particle of an element that retains the properties of the element. Scientific discovery is how the present day Atomic Theory was made up. The current atomic theory was formed by different scientists

Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However, many types of microorganisms are potentially pathogenic.

Title: Osmosis in quails’ egg Aim: To observe the effect of different concentrations of sodium chloride on a de-shelled quail’s egg To explain the effects in terms of osmosis Research Questions: Does the different concentrations of sodium chloride on a

The purpose of this experiment was to perform a wittig reaction, the horner-emmons wittig specifically, reacting an aldehyde with an ylide to make an alkene. This particular variation of the wittig reaction has several advantages: It gives only the trans

Be sure to address any questions posed in the lab procedure as well as any additional questions that your TA wants you to answer. You should also analyze any NMR spectra that you have from the reaction (if applicable). Spectra

Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane, while osmosis is the process in which water molecules
