Discuss three GASEOUS pollutants giving their sources, environmental effects, and what can be done to reduce the production or emission of each one. Give a solution for each, not an overall solution to pollution in general, or one solution for all 3.
Calculate the molarity of a solution of HBr if 34.80 mL of the HBr solution neutralize 0.834 g of Na2CO3. The following is the unbalanced equation for the reaction
Calculate the quantity of energy produced per mole of -235 (atomic mass = 235.043922 ) for the neutron-induced fission of -235 to produce -137 (atomic mass = 136.9253 ) and -97 (atomic mass = 96.910950 ). E= J/mol U235
One synthetic preparation of aniline involves reducing nitro benzene with iron and HCL, and then steam distilling the resultant aniline at 99 degrees Celsius. How much aniline codistills with each gram of water during the steam distillation.
at a particular temperature, N2O5 decomposes according to a first-order rate law with a half-life of 3.0s. If the initial concentration of N2O5 is 1.0x10^-6 molecules/cm^3, what will be the concentration in molecules/cm^3 after 26.1s
A sample of gaseous C2H2 (acetylene, or ethyne) was stored for one year, yet at the end of this period the sample remained unchanged and no graphite or hydrogen gas had been formed. Briefly explain why there is no inconsistency between the sign of..
