Compute the ΔH for this reaction and express your answer in kilojoules if the given . Bond Energies (kJ/mol) are N-Cl 201 , Cl-Cl 243 , N-H 389 ,H-Cl 431
a particle has a velocity equal to 0.25 c and a wavelength of 1.3 x 10^-16 m. Calculate the mass of the particle in kilograms. c=3.0 x 10^8 m/s
On a climb up mt. Whitney, the atmospheric pressure drops to 467 mmHg. What is the pressure in terms of the following units? a) atm; b) torr; c) in. Hg; d) Pa.
The blue color of dextran blue solution is due to the well-known, blue complex formed between starches and iodine. If you only had the absorption spectrum of this solution
its ground state absorbs 2.50 times as much energy as the minimum required for it to escape from the atom. Calculate the deBroglie wavelength of the emitted electron
Determine the mass percentage concentration of a sodium hydroxide solution produced by mixing 50.0 mL of a 25 % (density=2.45g/mL) sodium hydroxide solution with 10.0mL of H 2 O?
What is the relative spread (in ppt) of the two values? (Note: ppt is part per thousand. Keep one decimal place in your answer.)
Calculate the solubility (in grams per 1.00*10^2 mL) of magnesium hydroxide in a solution buffered at pH=10. How does this compare to the solubility of Mg(OH)2 in pure water
Determine how much Nitrogen gas is consumed if 13.6 grams of FeN are formed in above reaction?
Norborneol synthesis in this manner is stereoselective. So, there are two possible products one endo and one exo. Only one will form, but why aren't there actually four possible products since the alcohol can form on either carbon in the alkene?
