Calcium nitrate (Ca(NO3)2) solution (250.0 mL, 0.15 M) was mixed with sodium phosphate (Na3PO4) solution (50.0 mL, 1.0 M).
1- Show the balanced molecular, ionic, and net ionic equations.
2- Determine the limiting reagent for the above precipitation reaction.
3- Calculate the theoretical yield, in grams, of the precipitated solid formed (that is, the amount that could be made based on the amount of limiting reagent).
How does the attractive force that the nucleus exerts on an electron change with the principal energy level of the electron
The theoretical value can be computed from the atomic weights of the atoms involved. How
Consider a saturated colution of calcium oxalate, CaC2O4, in which the following reactions can occur: (CaC2O4)4 -2 (s) ---> Ca+2 + C2O4 -2 Ksp=1.3e-8
Give the balanced redox reaction for each possibility and explain your reason for selecting the reaction which will occur. Assume standard solution concentrations.
Terephthalic acid is an organic compound used in the formation of polyesters. It contains 57.8 percent C, 3.64 percent H, and 38.5 percent O. The molar mass is known to be approximately 166 g/mol. What is the molecular formula of terephthalic acid..
detailed reaction mechanism for the acid-catalyzed hydrolysis of lactose to its component monosaccharides
A silicon wafer is etched in a Cl2 plasma. A mass flow controller (used to meter the gas flow fed to the reactor) shows a reading of 100 sccm (sccm=standard cm3 per min; standard conditions are 273 K and 1 atm). The etching reactor operates at 100..
Write the ground state configurations of C2 and F2 and then predict which molecule should have the greater bond dissociation energy.
The Haber process is very important for agriculture because it converts N2 (g) from the atmosphere into bound nitrogen which can be taken up and used by plants. The reaction is N2 + H2->NH3
