Problem- Determine the element of lowest atomic number that contains a complete d subshell in the ground state.
I want to know how this is done please show all steps in detail
Why can the nature of the metal salt precursor be changed during the epoxide addition method so easily without altering
a piece of gold jewelry that weighs 9.35 g and has a volume of 0.654 cm3. The density of pure gold is 19.3 g/cm3 and the density of pure silver is 10.5 g/cm3.
Calculate the change in internal energy of the gas in each case of these processes.
The ultimate source of all chemical products is the earth (including its water and atmosphere). Sulfuric acid is a good example. It is made from burning sulfur in air to make sulfur trioxide then reacting the sulfur trioxide with water.
if 98 g grams of CaCN2 reacts with 59 g grams of H2O, what mass of NH3 will be formed.
If a few drops of water on the outside of the hot water syringe used to dispense the 5.00 mL sample into the calorimeter well for the Kcal determination fell into the well
Cyclopropane (C3H6) reacts to form propene (C3H6) in the gas phase. The reaction is first order in cylclopropane and has a rate constant of 5.87*10^-4/s at 485 C.
The reaction is found to be first order each in iodide and hypochlorite ions, and inversely proportional to the concentration of hydroxide ion present in the solution.
Calculate number of moles at STP to 3 significant figures for the following: 1 liter of methane gas at 730 mm Hg and 25.0 C. Give answer as ______ x 10
Explain how many samples of this size must be analyzed in order to give 90% confidence that the mean is known to within 1.2%. (mR2=Ks)
At a temperature T, a previously empty 5.00L flask is prepared by adding 1.20 mol SO2 and 1.5 mol of O2. Determine the concentrations of SO2, O2 and SO3 once equilibrium is established. KC=963
The CNOG ion is very unstable and is the reason why the mercuric compound is explosive. On the other hand, mercury cyanate, Hg(NCO)2, is not explosive. The cyanate ion (NCOG) is a stable ion. Use resonance structures and electronegativities to exp..
