Hazardous Chemicals Briefing at Your Job

Regardless of where you work or plan to work with the degree you obtain, chemicals will be involved. Look for a particularly hazardous chemical involved in your current workplace or one you might find in a future workplace, and prepare a presentation to brief your coworkers on the dangers of said chemical. Your presentation should include the following:

the molecular structure of hazardous chemical;

identification of the type of molecule (ionic or covalent);

identification of whether the molecule is polar or nonpolar and what that means with the situation(s) using the chemical;

relation of its chemical behavior to its structure;

if it is a large molecule, the identification of one central atom and its VSEPR shape;

identification of at least three bonds within the molecule and their bond lengths and enthalpies; and

any warnings or special precautions your coworkers must take when working with the chemical. (Hint: refer to the substance’s material safety data sheet that can be found through an online search.)

The presentation should be at least seven slides in length. Please pay attention to spelling, proper grammar, and punctuation. You must use at least two sources, one of which may be the textbook and at least one other must be from the CSU Online Library. Be sure to include proper APA citations for any information obtained through external resources. Title and reference slides do not count toward the minimum slide requirement.

Hydrogen Sulphide
Hydrogen Sulphide	
Student name
H2S An Introduction
A colourless gas with the pungent smell of a rotten egg
Highly inflammable and toxic
Prime most chemical hazard in the production of natural gas
A precursor of sulphur element
Heavier than air very marginally
Also exists as liquid compressed gas
The gas naturally occurs in the natural gas fields, crude petroleum diggings, volcanic areas and hot springs. It is also inhaled just to go knockdown at places of sewage treatment plants, food processing plants, paper pulp industries, organic manure decomposition pits, etc., Since we work in the natural gas field, it is important for us to understand the ill-effects of the hazardous gas. The gas is also called as stink damp, manure gas, sewer/swamp gas. 
Even though H2S is only minutely different in density with air, a little more addition of air will lead to explosion. It is a reducing agent. It readily burns and ends up forming sulphur dioxide. 
Exposure to liquid H2S can cause frostbite or blue skin disease.

Molecular Structure
VSEPR model is used to draw the structure of a molecule based on the valence electrons revolving its nucleus.
Valence electrons take part in bond formation
The Lewis structure of a molecule represents its valence electrons
Valence shell electron pair repulsion- VSEPR . The theory is named after Ronald Gillespie and Ronald Nyholm as Gillespie-Nuholm model.

		Lewis dot structure of H2S
There are 2 atoms of Hydrogen and 1 atom of Sulphur. 
As per the octet rule,
	Total valence electrons = 6 of sulphur + 2 of 	hydrogen = 8
Two electrons from sulphur help form bonds with two atoms of hydrogen. The remaining 2 non bonding electron pairs are shown in the figure. 
The angle is less than 1800 but the non bonding pair of electrons repel each other and reduce the angle to 104.50
Hence it forms a bent molecular geometry
Electronic configuration of sulfur.
