What is a chemical or biological hazard that is present at a facility or familiar with?
What are the properties of the hazard that would affect the exposure potential in an occupational setting?
What are the potential health effects associated with the hazard?
How would one go about ensuring that the health effects on the facility were properly mitigated as an industrial hygienist or safety officer?
Concentrated sulfuric acid is used as a catalyst for the esterification of acetic acid in the preparation of isopentyl acetate. Why is sulfuric acid needed if another acid, acetic acid, is already present
if copper has a photoelectric threshold wavelength of 279 nm calculate the velocity ms of the electron emitted when
A gas contains a mixture of NH3(g) and N2H4(g), both of which react with O2(g) to form NO2(g) and H2O(g). The gaseous mixture (with an initial mass of 61.00 g) is reacted with 10.00 mol O2, and after the reaction is complete, 3.970 mol of O2 remai..

the precipitation of each ion must be complete (>99.9%) and there must not be more than 0.1% (by weight) of one of the other ions in the precipitate. Explain your answer: nature of precipitate, pH, concentrations etc. Be quantitative in your answe..
The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 12.0 . How many moles of gas () remain in the cylinder
A catalyst decreases the activation energy of a given reaction by exactly 15 kJ/mol. By what factor does the reaction rate increase at 25oC when the catalyst is used
Explain why does the wavelength of light emitted by CdSe nano particles shift from red to green as particle size is reduced. Explain what is this phenomena called.
