sulfur Definition and 36 Threads

I have a problem from 3 weeks… I broke a thermometer that contained mercury. The mercury balls hid in the cracks in the parquet in the floor. I found information in some chemical webiste, that the only thing what I can do, is to cover this mercury with ground sulfur to neutralize the mercury...

Hi, I am a first-year university student in engineering and for this year I have to do a presentation( with related experience ) about the physical implication of geoengineering methods. The theoretical aspect seems quite understandable, my principal problem is to find a clear experience with...

Is the final answer given is correct? From where 96 (highlighted) came? Molar mass of $SO_2$ is $64.0588 g \times mol^{-1}$

Hi All, First post here. I'll get straight to the point. Thinking about ideas for a novel. Would it be theoretically possible to have a world without sulfur and charcoal? The idea would be a planet targeted for colonization that doesn't have elements needed for gunpowder. What are the...

Anybody know more about this? It is in DISCUSSION forums since I do not see any decent references on the subject. Maybe I'm having a bad day... ##SF_{6}## - Prevents fires from electrical shorts, used in high kVa distribution lines - at connection points, substations, and "ties" Apparently...

Hello My name is ron and i am a mechanical engineering in pump factory. In some project i work on, i have fluent that contains sulfur (less then 10 %). my question is how natural rubber react with sulfur? and if its currect to use natural rubber? thanks

A sample of sulfur having a mass of 1.28 g combines with oxygen to form a compound with a mass of 3.2g. What is the empirical formula. So what i did is found the mass of oxygen which is 1.92g . Then converted the 1.28g S to 0.04 mol. Then converted the 1.92g O2 (as it says oxygen, or should it...

Dear all I have 250g of Copper 250g of Tin and 250g of Sulfur. Everything is in powdered form. Heated up in closed container wit surrounding nitrogen flow to avoid contact with Oxygen. Heating ramp is 3 hours to 1000K. What reaction will be the leading reaction? How to calculate how fast will...

what is the properties of chimcal reaction for carbon and sulfur in gunpowder...and what different reaction happens if the gunpowder have just carbon without sulfur

how to calculate of heat combuation for sulfur

same question.

Homework Statement http://i.minus.com/jsdp6WZ2nqRY9.jpg Homework Equations Sulfur is sp2 hybridized. Sulfur is also nonpolar having an AXE of AX3 and no lone pairs. It is trigonal planar. The Attempt at a Solution I'm not sure if sulfur can be represented by three equivalent...

Hybridization of carbon Pretty sure my professor is wrong once again. SO2 should have two double bonds which gives the sulfur a minimal formal charge and two signs bonds. The two sigma bonds imply sp hybridization, not the blatantly wrong circled answer.

I googled it and got both answers, "yes" and "no." What I mean is: O-H-S, F-H-S, N-H-S, etc. Ex.'s of "yes": http://www.ncbi.nlm.nih.gov/pubmed/19089987 [PLAIN]http://pubs.rsc.org/en/content/artic.../ce/c0ce00760a[/URL] Ex. of "no": http://www.nature.com/nature/journal.../149218a0.html

Equivalent weight of sulfur in SCl2 is 16,what is the equivalent weight of S in S2Cl2? [S=32,Cl=35.5] I know that the answer is 32. But how how can the equivalent weight of Sulfur be 32? We know that equivalent weight=atomic weight/valency Now sulfur has variable valency of 2,4,6 .So the...

I have a need to capture some free sulfur and graphite molecules in the anodizing layer of aluminum, preferably a hard anodizing which uses higher current levels and lower temperature than normal anodizing. I had imagined puting DMSO for the sulfur molecule in the sulfuric anodizing solution and...

When we strike a match which is made of sulfur against a hard surface (I don't know what the surface is made of) a flame is produced. That flame can then cause a piece of wood to burn. We can also see the flame. Why? Let me take my best guess since this website likes people to try...

Homework Statement A coal-fired steam power plant operates on the ideal Rankine cycle. Feedwater from the condenser at P1= 10 kPa is pumped to the boiler at P2= P3 = 20 MPa, where it is superheated and exits the boiler at T3 = 550 °C. The moisture content in the turbine is not to exceed 12%...

I would like to oxidize suspended elemental sulfur to sulfate in a solution. Any suggestions?

I've heard many times of the first systematic study of static electricity: Otto von Guericke would spin a ball made of sulfur and rub it by hand, building up an electric charge. To make a sulfur ball, he would pour molten sulfur into a hollow glass globe, wait for the sulfur to harden, then...

My understanding is that for EAS, Friedel-Crafts Acylations/Alkylations will only work for halobenzenes or better (in terms of electron donating groups). Does this mean that F-C won't work for a halobenzene that also has a nitro group on it, due to the extreme withdrawing effects of the nitro...

Hi, I'd just like to know why fertiliser producers refer to "the percentage by mass of sulfur present as sulfate" in their fertilisers? Thanks!

Hi peeps can someone help me with this? The central atom would be sulfur correct? So that means sulfur will invoke hybridization sp2 would be use since there are 3 bonds? However when we invoke hybridization there are 2 2s electron and 2 2p electrons in the orbital(doesn't really know how to say...

I quote from a fellow chemistry teachers' letter (Mike Thompson): "Many colleagues will know that when solid sulphur is heated below some lightly packed iron wool in a test tube or boiling tube a standing wave is sometimes set up and a whistling noise is heard (around middle C with a boiling...

I'm just curious about how the sulfer's molecular orbitals would be described in sulfer trioxide. I can see that the molecule is trigonal planar, but how is it involved in 3 pi bonds? Also I'm sure that a d orbital or two is involved... but can't sp3d, sp3d2 orbitals only do sigma bonds? Thanks.

For the last several months I've been trying to locate sulfur in bulk so I can try out something called sulfur casting (lost-wax casting using liquid sulfur instead of molten metal). All I've been able to find is five pound bags of something called soil or garden sulfur at nurseries and home...

Is there a quantitative test for the amount of sulfur dioxide in orange juice. Nothing too complicated, I am only in year 11. Can it be done using titration?

Why is fire hotter when fueled by sulfur as compared to say, paper, wood, or charcoal?

I need help could someone please help me with this problem? How many atoms are there in 3.90 moles of sulfur (S)?

I was wondering if there was any research into how the nervous systems work inside of sulfur based life forms. I think I remember seeing somewhere organisms complex enough to resemble shrimp existed, but the only thing I’ve been able to find in my own research was worms.

Well I've found this recipe to extract Potassium Nitrate from nitrate bearing potting soil containing 0.09% nitrate nitrogen and I've also found this one soil (well its more like rocky gravel) for turfs that contains 9.00% nitrogen nitrate. Okay so my question is can i extract the one with 9.00%...

I know that hydrochloric acid reacts with a heated mixture of iron and sulfur, but why does it not react with an unheated mixture of iron and sulfur? (During a demonstration, I could see a soggy mixture of the powder and fillings in the acid, and I noticed nothing so I am assuming no reaction...

The first step in the manufacture of sulphuric acid involves burning sulphur in air to produce sulphur dioxide. Why must the air used to burn the sulphur be as clean as possible? I'm not sure whether or not we should concerned ourselves with: 1. how the impurity affects the rate of...

Is there an easy way to make/extract Sulfur (/Sulphur)? For example, making sulfur by taking the sulfur out of sulfuric acid? I don't think this is possible though, is it? or by extracting it from sulfur soil and getting a relatively high purity?

Will boiling ground water that contains sulfur produce a yellow sulfur residue. Thanks, --Keith
