A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 210.0 MPa. The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand a force of 6.20 MN. Calculate the maximum safe diameter w of the port
An antacid tablet contains 0.1 g of magnesium hydrogencarbonate, Mg(HCO3)2. What mass of stomach acid, HCl, will it neutralise? The reaction between Mg(HCO3)2 and HCl is: Mg(HCO3)2 + 2HCl → MgCl2 + 2CO2 + H2O
Rate Law for Proposed Mechanism, Consider the reaction 2NO(g) + O2 ---> 2NO2 (g). The following mechanism has been proposed to explain the experimental rate law
What is Nitroglycerin's molar mass if the addition of 0.454 g of nitroglycerin to 100.0 g of benzene changes the solution's vapor pressure to 94.85 mm Hg?
a quantity of ice at 0.0 degrees Celsius was added to 33.6grams of water at 21.0 degrees Celsius to give water at 0.0 degrees Celsius. the heat of fusion of water is 6.01 kj/mol and the specific heat is 4.18 J/(g*celcuis) how much ice was added?
