Problem- Why do firefighters recommend the use of a deluging volume of water when extinguishing an oxidizer-supported fire? What may happen to a large (i.e., 30-50lb) container of trichloro-s-triazinetrione, or calcium hypochlorite, if it is left to sit in the water and muck remaining in a building after firefighting efforts have ended, but clean-up will not begin for several days? The assumption here is that the plastic container has been compromised in some way by the heat of the fire and possibly creating cracks in the base or sides.
This is not a problem given in the book, so I just need the full solution of deriving!
it is known that 1500 revolution are required for the 6000-ib flywheel to cost to rest from an velocity of 300 rpm.
List the following gas phase ion pairs in order of the quantity of energy released when they form from separated gas-phase ions. Start with the pair that releases the least energy.
a strip of mg of mass 15g is dropped into a beaker of dilute hcl. determine the work done by the evolution of h2 in the
it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.338 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibri..
Question- If you separated the supernatant from part a) above and treated this supernatant with 3.0 M HCl would a precipitate of PbCl2 be observed. Rationalize your answer mathematically.
A student carefully diluted 50.0mL of 6 M HCI solution in 950.0 mL of distilled water. calculate the molarity of the diluted acid solution. Explain why this diluted HCI solution cannot be used as a standard solution of acid.
Air is 21 mole percent oxygen, that is, 0.21 atm oxygen at 1 atm. Suppose the pH of the water is 5.28 and that the concentration of iron(II) in the water is 5.38x 10-5 M, what is the potential of the corrosion reaction under the above conditions a..
Question- When subjects maximum oxygen consumption is known, we can predict his maximal steady state running speed. Estimate a runner's maxomal steady state speed for each of the following points- 40 ml.kg-1.min-1 46ml.kg-1.min-1 and 54ml.kg-1.min..
the carbon dioxide that is exhaled by astronauts who are on a space shuttle is scrubbed by pumping the air through
A vessel which is 5 m^3 is filled with propylene. The pressure inside the vessel is 470 psi, and the temperature of the vessel is 25 C. A) How many kg of propylene are in the vessel?
At high temperature, hydrogen and carbon dioxide will reversibly react to form carbon monoxide and water vapor. At 986 C there are 0.11mol of each product and 0.087mol of each reagent in a 1.00L flask. What is Kc under these conditions
a gas mixture contains 5.6 g of N2, 1.4g of h2, and 27.6 of CH4. What is the mole fraction of h2 in the mixture
