Do you think a comparable spill of a water-insoluble liquid that has a density of 1.20g/mL would have been as harmful to waterfowl and aquatic mammals, assuming that the toxicity of the liquid was comparable to that of petroleum?
A chemistry student needs 60.00 mL of chloroform for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of chloroform is 1.48 g x cm^-3.
Sodium methoxide CH3ONa is a weaker base than BuLi or nBuLi butyllithium. Recommend an explanation why it is not surprising to find that a weaker base is sufficient to prepare the Horner-Emmons-Wittig reagent.
3H2 (g) + N2 (g) 2NH3(g), Kc = 6.0 × 10-2 at 500°C for this nitrogen fixation reaction. What is the equilibrium concentration of N2 If 0.250 M H2 and 0.050 M NH3 are present at equilibrium?
Up to Iron "Fe", the number of proton and neutron are about equal, after Fe the number of neutron began to rapidly increase, with respect to the number of proton, why?
Determine the value of the equilibrium constant at this temperature - Ammonium Hydrosulfide NH4HS yields NH3(Ammonia) and Hydrogen sulfide
I am trying to understand the effects of leachate from landfills and its effects on groundwater, and since I am in environmental health- its effects on the human health.
A 1.90 mole quantity of NOCl was initially in a 1.50 L reaction chamber at 400°C. After equilibrium was established, it was found that 36.0 percent of the NOCl had dissociated.
calculate (a)molality? (b)molarity of NaCl? (c) What is the mass/mass and remove the most loosely held e- from a gaseous atom in a ground state
Find the lowest temperature of vaporization and the highest temperature when there is liquid left over and Determine the range of temperatures which could be used for this process.
determine the molecule weight of the liquid and the density of the vapor under these condition?
An aqueous solution is six percent by mass methanol,, and has a density = 0.988 g/mL. Determine the molarity of ethanol in the solution.
The [OH-] = 1.3 x 10^ -6 M for a 0.025 M solution of a weak base. Calculate the value of Kb for this weak base.
