What is the theoretical yield of aluminum oxide if 1.60 mol of aluminum metal is exposed to 1.50 mol of oxygen?
if molarity of a 2000ml solution is 4.0M NaCl, how many moles of NaCl are dissolved in that solution.
calculate the number of moles of AgCrO4(Ksp=9.0x10^12) that will dissolve in 1.00L of 0.010 M K2CrO4 solution. what will be the ion concentrations at equilibrium?
Four (4.00) moles of a perfect gas at 250.0 K and 1.50 bar pressure undergo a reversible isothermal compression until the pressure becomes 3.00 bar.
Determine what volume would it occupy at zero degree Celsius temperature at same pressure? Express your Answer in units of mL
A line in the emission spectrum of an atom occurs at a wavelength of 560 nm. What is the energy difference between the two energy levels involved in this emission.
What is the molarity of a 1.304 L solution that is made from 14.80 g of NaCl?Answer in units of M.
Choose one of the following atmospheric issues: air pollution, global warming, ozone depletion, and acid deposition. Then, respond to the following,
Draw the crystal-field energy level diagram for the 3d obitals and show the placement of d electrons assuming this is a weak-field complex ion.
A weak monoprotic acid is exactly neutralized by 11.17mL of a standardized 0.1455M NaOH solution. If the Ka of the acid is 0.00084, what is the pH at the half-equivalence point.
A bottle containing 345 g of cleaning solution is used for carpets. If the cleaning solution has a specific gravity of 0.850, what volume of solution was used?
Sodium atoms(Na) emit light with a wavelength(λ) of 330 nano meters when an electron moves from a state of 4 p orbital to a state of 3 s orbital now you just need to determine the energy difference between the orbitals.
