Consider the following reaction. CO(g) + Cl 2 (g) > COCl 2 (g) The mechanism is believed to be, (1) Cl 2 2Cl (fast equilibrium) (2) Cl + CO COCl (fast equilibrium) (3) COCl + Cl 2 > COCl 2 + Cl (slow) (4) ...
What would be the effect on our body chemistry if large numbers of enzymes were to become malformed and how do they become malformed?
For the equilibrium 2IBr( g )?I2( g )+Br2( g ) Kp =8.5×10-3 at 150 °C. Part A: If 2.7×10-2 atm of IBr is placed in a 2.0-L container, what is the partial pressure of IBr after equilibrium is reached? Express your answer ...
When .514g of biphenyl (C12H10) undergoes combustion in a bomb calorimeter, the temperature rises from 25.8 degrees C to 29.4 degrees C. Find delta E(rxn) for the combustion of biphenylin kJ/mol. The heat capacity of the ...
C-14 analysis of the Shroud of Turin has shown that approximately 93% of the 14C present in living matter is still present in samples taken from the shroud. Based on this information, what is the approximate age of this ...
How many grams of H2SO4 must be dissolved into 0.709 L of solution to generate a concentration of 0.303 M?
Why is (NH 4 ) 2 CrO 4 a molecular compound if ionic is metal + nonmetal and molecular is nonmetal+nonmetal? The Cr is a metal and the NH4 and O4 are non metal so it is metal+non metal but why cant it be ionic instead o ...
Suppose a tank is filled with A2(g) so that initial pressure is 0.8688 atm at temperature of 298K. Some of the A2(g) dissociates and when the system reaches equlibrium the total pressure in the tank is 1.275 atm. Calcula ...
Hydrazine, N2H4, is dibasic and has Kb1 = 3.35x10-7 and Kb2 = 1.42x10-16. Calculate the concentration of OH- ions in a 29.91 M aqueous solution of hydrazine. Express your answer in mM.
1. Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC 8 H 4 O 4 . This is often written in shorthand notation as KHP. If ...
