Compound A has a solubility of 18 grams per 100. grams of water at25 degrees C. Cooling a saturated, 200.-gram solution of compound Afrom 84 degrees C to 25 degrees C results in a precipitation of 11grams of the compound. Calculate the solubility of compound A at 84degrees C.
heptapeptide upon HCL hydrolysis produced equimolar amounts of ASP, CYS, GLU, LYS, PHE, TYR, VAL and ammonia. Exposure of the intact heptapeptide to FDNB followed by hydrolysis produced DNP-VAL
you just need to find out Which Substance (given) will be to fall to the bottom of the beaker by combining them with H 2 O In A Beaker?
How do I write the reaction of the borohydride ion with water to form one molecule of H2 with curvy arrows
The bond dissociation energy of H2 and Cl2 are 436 and 242 kJ/mol, respectively. The Pauling electronegativity of H and Cl are 2.3 and 3.2. What is the HCl bond dissociation energy
Give a stepwise mechanism showing the base-induced formation of diphenylacetylene from meso-stilbene dibromide. Use curved arrows to symbolize the flow of electrons.
Furthermore, by carefully monitoring the volume change it is determined that 92kJ of work is done on the mixture during the reaction. Calculate the change of energy of the gas mixture during the reaction in kJ.
The calorimeter contains 1.00 kg of water (heat capacity of H2O = 4.184 J/g°C) and the heat capacity of the empty calorimeter is 0.10 kJ/°C. How much heat is released per gram of oil shale when it is burned?
Write balanced nuclear equations for (a.) the loss of an alpha particle by thorium- 230 and (b.) the fission of U- 235 to give Ba- 140, two neutrons, and another nucleus.
In the expression for f which you obtain, use a power series expansion of the exponential function
