The following exposure limits are for Hydrogen Fluoride * Chlorine Pentafluoride is a CORROSIVE CHEMICAL (measured as Fluorine): and contact may severely irritate and burn the skin and eyes with possible eye damage. OSHA: The legal airborne permissible exposure limit * Chlorine Pentafluoride is a HIGHLY REACTIVE (PEL) is 3 ppm averaged over an 8-hour CHEMICAL and a DANGEROUS EXPLOSION workshift. HAZARD.

Any additional paper needed please attach. Submitted Work: 1) Completed packet. Questions: Please send email to your instructor and/or attend published virtual office hours. Schedule: Date Activity Monday (4/27) Read Sections 9.3, 9.5 in your textbook. Tuesday (4/28) Read and work through questions 1-9 Wednesday (4/29) Read and work through questions 10-14 Thursday (4/30) Read and work through questions 14-18 Friday (5/31) Read and work through questions 19-21 How are the chemical formula and name of a molecular compound related? Why? When you began chemistry class this year, you probably already knew that the chemical formula for carbon dioxide was CO2. Today you will find out why CO2 is named that way. Naming chemical compounds correctly is of paramount importance. The slight difference between the names carbon monoxide (CO, a poisonous, deadly gas) and carbon dioxide (CO2, a greenhouse gas that we exhale when we breathe out) can be the difference between life and death! In this activity you will learn the naming system for molecular compounds. Model 1 – Molecular Compounds Molecular Number of Atoms Number of Atoms in Name of Compound Formula of First Element Second Element ClF Chlorine monofluoride ClF5 1 5 Chlorine pentafluoride CO Carbon monoxide CO2 Carbon dioxide Cl2O Dichlorine monoxide PCl5 Phosphorus pentachloride N2O5 Dinitrogen pentoxide 1.

Definition of High Hazard (HH) Gases For these guidelines, any gas meeting one or more of the following definitions based on International Fire Code (IFC) and National Fire Protection Association (NFPA) standards: 1.1. Flammable gas – a material that is a gas at 68ºF (20ºC) or less at an absolute pressure of 14.7 psi (101.325 kPa) when in a mixture of 13% or less by volume with air, or that has a flammable range at an absolute pressure of 14.7 psi (101.325 kPa) with air of at least 12%, regardless of the lower limit 1.2. Pyrophoric gas – a gas with an autoignition temperature in air at or below 130ºF (54.4ºC) 1.3. Health Hazard 3 (HH3) gas – material that, under emergency conditions and according to the standards, can cause serious or permanent injury 1.4. Health Hazard 4 (HH4) gas – material that, under emergency conditions and according to the standards, can be lethal The storage and usage of a gas or gases meeting any of the above definitions must follow all applicable IFC and NFPA guidelines and the requirements outlined in this document. Consult EH&S for specific guidance on gas mixtures containing corrosive, flammable or poisonous gas components (ex. 1% carbon monoxide/nitrogen, 5% hydrogen sulfide/helium). 2.
