Question:
What is the theoretical yield of aspirin if 190 kg of salicylic acid is allowed to react with 128 kg of acetic anhydride?
the piston of an internal combustion engine compresses 434 ml of gas. the final pressure is 15 times greater than the
A gas is placed in a storage tank at a pressure of 20 atm at 20.3 C there is a small metal plug in the tank made of a metal alloy that melts at 125C what is the maximum pressure in the tank?
Question- Calculate either solubility or the solubity constant Ksp for a) CAC2O4*H2O has a solubility of 7.36E-4 g/100mL what is tis ksp value. How do I calculate this. b) FE(OH)3 has ksp value of 2.79E-39 what is the solubiltiy in g/100mL please ..
If a given element has a mass that is 5.81 times that oc 12 C how do I figure out the mass and the element. Do I just times 5.81 times 12.0107? Therefore it is Ga
rate constant for the decomposition of N2O5 to NO2 and O2 at 70 degree celsius is 6.82 x 10^-3 s-1. Suppose we start with 0.300 mol of N2O5(g) in a .500L container. What is the half-life of N2O5 at 70 degrees celsius?
what is the main difference between, 2s or 3s or 4s orbitals, or 2p, 3p or 4p. is it just that they are bigger?
Determine Ssys separately for the volume and temperature changes and show that ?Ssys = 0 for a reversible adiabatic process. If the expansion had instead occurred irreversibly against a constant external
Draw a Lewis structure for H3C-NO2. Both oxygen atoms are directly attached to the nitrogen atom. If you take formal charge considerations into account, how many -bonds are in the molecule?
Considering the following equation, how many moles of water will be made by fully reacting 12 moles of NH3?
Uric acid dissociates as shown in the figure at the right with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range. Its solubility in urine depends on the relative amount of protonated and unprotonated forms. A urine sam..
A triiodide solution was being examined by coulometry. The instrument measured 33.7 coulombs from the quantitative reduction of triiodide to iodide ion for a 10mL solution. Compute the concentration of triiodide in the solution.
