Can you explain the second step to third step transition in the citric acid cycle in chemistry?
A 0.7818g sample containing phosphate (PO4 3-) was dissolved. The phosphate was precipitated as MgNH4PO4 by addition of aqueous Mg2+ followed by addition of aqueous ammonia. After filtration and washing,
Presume that the reaction of Fe3+ and SCN- produces Fe(SCN)2 (+). 5.00mL of 2.0mM Fe3+ is mixed with 5.00mL of 2.0mM SCN-. Determined the equilibrium concentrations of Fe(SCN)2(+) to be 0.3mM.
The solubility of AgCrO4 is several times greater than that of AgCl, so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution.
When the following reaction is balanced in acid solution using the lowest possible whole number coefficients, the coefficient of H+ will be: S8 + NO3- --> S4O62-+ NO2
The bond energies of Cl2 and F2 are 242kj/mol and 155kj/mol, respectively. Calculate the bond energy of a Cl-F bond.
What is the reason for using a phase transfer catalyst? a)It is used to transfer the catalyst to the active site of the reaction b)It serves as a proton transfer agent which moves protons from a base to an acid
Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the C^14 has decayed to 1/16.0 of the original amount. How long ago was this plant alive. Express your answer numerically in years.
Ultra-high-vacuum experiments are routinely performed at a total pressure of 1.0 x 10-10 torr. Calculate the binary number of collisions, Z11, of N2 molecules (per liter per second) at 350 K under these conditions. The collision diameter of N2 is ..
Write equilibrium reaction for HNO 2 and compute equilibrium concentrations of all species, compute pH , OH - , and the pOH
the concentration of mg2 in seawater is 0.052 m. what hydroxide concentration is needed to remove 90 of the mg2 by
a solid,is thought to be either zinc or lead(2)nitrate.how are we going to determine the identity of the solid?
Draw the structure of any D-ketoheptose in the open chain form, and answer the following questions (you must use either Haworth projection or chair conformation in each of the points below)
