Exploring the inner space of carbon nanotubes Hisanori Shinohara Jpn. Static electricity can be a problem whenever the humidity is low. Use an indicator made from red cabbage juice to determine whether household products are acids or bases.
We can teach you about the general structure of an atom, but you need to study atoms from different elements to really learn how atoms work. Virtual Chembook - this nicely-done site by Charles Ophardt of Elmhurst College covers a wide swath of general, organic, and environmental chemistry.
Environmental Toxicology, Volume 19 6: Use an indicator made from red cabbage juice to determine whether household products are acids or bases. This diver will sink or float on command. Static electricity can be a problem whenever the humidity is low.
How to pass chemistry - sound advice that is widely ignored. These are llive classroom lectures, given by Prof. That rusting happens because the iron Fe in the metal combines with oxygen O2 in the atmosphere.
In this experiment you will find out how you can hold a balloon directly in a flame without breaking it. This experiment will tell you why.
Clean the tarnish off of silverware. Registration is required, but is free. Welcome to the Lab, again. In this activity you will examine the behavior of rubber as it is affected by heat, a form of energy. A reaction could include atoms, ionscompounds, or molecules of a single element.
Thorough coverage of the basic ideas relating to units and dimensions, the SI system, accuracy, precision, and uncertainty in measurements, significant figures and rounding off, treatment of random and systematic error, standard deviation. Use a heavier than air gas to suspend soap bubbles.
Will a bowling ball sink or float in water. Results of this study showed there was approximately 2-fold greater risk of having a stillbirth if the mother lived within 1 mile from an agricultural area which used organophosphate - pyrethroid - carbamate - or chlorinated pesticides.
The silver chloride example only focused on the ions. But he said his results underscored the importance of studying toxic chemical effects in a context approaching the complexity found in natural ecosystems.
Letters make up those words. Ever played with a Lightstick.
This study conducted at the US Army Institute of Surgical Research and Texas Tech University Health Science Center in Lubbock Texas found that cancerous human breast tissue contained the chemical heptachlor epoxide found in the common home pesticide chlordane at levels 4 times higher than non-cancerous breast tissue.
Build your own colorful bead bottle to amaze your friends. The power of wind is harnessed in this experiment. Bonds between atoms are broken and created to form new molecules. Create a "cartesian diver" inside a 1 or 2 liter plastic bottle. This will tell him the number of immune system fighting white blood cells you have.
A water‐compatible variant of a click‐like polymerization between alkynoates and secondary amines to form β‐aminoacrylate synthetic polyethylene glycol (PEG) based hydrogels was developed. Cell culture experiments indicate cytocompatibility of these gels with >90 % viability retained in THP‐1 and NIH/3T3 cells after 72 hours in culture.
Thin-Layer Chromatography You will need to bring your package of TLC plates on this day. Not all plates will be used in this experiment; some will be needed in lab the following week.
The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab.

EXPERIMENTS ON ELECTROLYSIS OF SODIUM CHLORIDE. Mike Clark. Toowoomba, Australia. Electrolysis of sodium chloride solution with inert electrodes can be done in several different ways, producing different sets of products.
The experiments listed below are not necessarily in the order that they will be performed in lab! Please consult your syllabus for the exact schedule of your Chem 10 experiments.
