How is sulfur dioxide formed in a combustion reaction?
Sulfur dioxide is present in many fuels either as H2S, sulfur or sulphidic organic compounds (R-SH) like mercaptans or disulfides. In combustion, these sulfurs are combined with oxygen to produce SO2 and some SO3. Both SO2 and SO3 can combine in further atmospheric reactions to produce sulfurous or sulfuric acids.
How many covalent bonds can an atom of fluorine form?
Just one. Fluorine has 7 electrons in its outermost shell so sharing an electon with another atom in a covalent bond takes its shell up to 8, the noble gas configuration. The covalent bonds that luorine forms are generally highly polar because of fluorines high electronegativity. This is an example of the "octet" rule.
Why is sulfur important to life?
Sulphur is essential for the synthesis of vitamin B1. It helps in the digestion of fats and controls the metabolism of carbohydrates. It is essential for healthy hair, skin, and nails. Along with B complex vitamins, it aids the liver in bile secretion. It is believed that sulphur ejects some of the waste and poisonous matter from the system. It helps to keep the skin clear of blemishes and makes it glossy. Sulphur creams and ointments have been remarkably successful in treating a variety of skin problems. sulfur can be good in London in 1953 sulfur killed 1000 hi joe sulfur is bad for you why do you think that it is bad !!!
How many valence electrons are in NF4?
sulphur has 6 v.e f has 7 each so total 34 v.e sf4 has a trigonbal bipyramidal structure. it has 1 lone pair of electrons too. "which do not enter into bonding sf6 is possible too. actually... a trgonal byprimidal is a structure with 5 electron groups (Bonding electrons + lone pair electrons). SF4 only has 4 electron groups around it,(all valnce electrons bonded with fluorine and no lone pairs) so it is actually has a tetrahedral geometry. sp^3.
What is a group of many islands?
An archipelago is a group of many islands clustered together in a chain or cluster.
How many fluorines does sodium have?
If you think to sodium fluoride (NaF) the formula unit contain one fluorine atom.
How many electrons are there in sulfurs valence shell?
Sulphur has 16 electrons. Correction: there is 16 in total, but 6 in the outer (valence) shell.
How many electrons in sulfurs outer level?
There are 2 electrons in the inner level, 8 electrons in the middle level, and exactly 6 electrons in Sulfurs outer level.
What are sulfurs characteristics?
Sulfur is a yellow, solid non-metal element with a distinct odor and taste. It is brittle and can be found in various minerals and ores. Sulfur is essential for life and is involved in many biological processes.
How many electrons in sulfurs third ring?
The number of electrons in Sulfur atom is 16. Therefore there are 6 electrons in its 3rd ring.
How many bond angles of IF7 molecule are 90 degrees?
The molecule of iodine heptafluoride has a bi-pyramidal pentagonal shape. All of the F-I-F angles between two fluorine atoms in axial and equatorial planes are equivalent to 90 degrees. Therefore there is five of them.
Name the triatomic gas?
There are many tri-atomic gases. However, here's a few to be going on with. O3 = Ozone CO2 = Carbon dioxide H2S = Hydrogen Sulphide.
How do you balance c4h8s2 o2 CO2 H2O so3?
Balance: C4H8S2 + O2 --> CO2 + H2O + SO3 Work out how many S, C and H on the left and then balance for the right. Then add up how many O this gives on the right and divide by 2 to get number of O2. C4H8S2 + 9O2 --> 4CO2 + 4H2O + 2SO3
What is the composition of Teflon?
Teflon is a compound that we call a polymer. These polymers are small repeating units that all look the same, but thousands combine together to form long chains. The scientific name for teflon is Polytetrafluoroethylene. This simply means in plain English many units of 2 carbons and 4 fluorines. One unit would look something like: F F | | CC | | F F and this unit is repeated many thousands of times to form the long chains of the polymer. The single unit is called a monomer.
What are the three major chemical forces bonds that stabilize a protein's native state?
I would start with the covalent disulphide bod between two sulfurs that is the strongest bond in any protein. Then there are many hydrogen bonds, not strong individually, but so many of them make for over strength. Probably hydrophobic and hydrophillic interactions bring up the rear in this listing of bonds in proteins.
How many neutrons are usually found in sulfurs nucleus?
The mass number indicates the number of protons AND neutrons in the nucleus. Since the number of neutrons can vary, so can the mass number. The different versions of elements based on the number of neutrons are called isotopes. Sulfur-35 has an atomic mass of 35. So, it has a total of 35 protons and neutrons in the nucleus. Since sulfur always has 16 protons, then the number of neutrons in this isotope is 19. (35 - 16 = 19)
How is sulfur dioxide formed in a combustion reaction?
