Sketch a qualitative MO diagram for [Ni(NH3)6]2+ and identify the portion of the diagram considered by crystal-field theory. Imagine the ammonia ligands were all exchanged with a pi-donor ligand. Show how the MO diagram would be impacted.
What is the difference in volume (in mL) between the water vapor and liquid water? (Assume the density of liquid water is 1.0 g/mL.) C. Why is it dangerous to heat a closed container of liquid to its boiling point?
If it takes 526 J of energy to warm 7.40g of water by 17°C, how much energy would be needed to warm 7.40g of water by 55°C
calculate the pH of a solution contaning 0.2m acetic acid (pka=4.7) and 0.1 m sodium acetate? a. write the equation ph=pka+log [A-]/[HA]
Total pressure in kPa 10 seconds after initiation of the reaction if initially there was 88.3kPa of pure N 2 O 5 vapor Enter the total pressure in kPa 10 minutes after initiation of the reaction.
draw a lewis structure of the molecule and indicate the number of bonds and orbitals used in bonding. Show electron configurations of the central bonding atom in both the unhybridized and hybridized states.
In a vessel with a volume 3 m^3 you put 0.03m^3 of liquid water and 2.97m^3 of water vapor so the pressure is 101.33 kPa.
Ethers can be prepared by SN2 attack of an alkoxide ion on a alkyl halide. Suppose you wanted to prepare cyclohexyl methyl ether, shown below, using the SN2 reaction
Isopropyl alcohol is mixed with water to produce a 31.0% (v/v) alcohol solution. How many milliliters of each component are present
Metal X was plated from a solution containing cations of X. The passage of 48.25 C deposited 31 mg of X on the cathode. What is the mass of X (in grams) per mole of electrons.
In the reaction between glucose and oxygen 10.0 g of glucose reacts and 7.50 L of carbon dioxide is formed. What is the percent yield if the density of CO2 is 1.26 g/L?
Consider a cylindrical container partially filled with ethanol (C2H6O). Using the model in which ethanol vapor pressure is a result of equilibrium between the rate of ethanol evaporation and condensation.
if the density of water at 25.2 degree celcius is 0.997962 g/cm^3, what is the volume of liquid in mL whose mass is 20.762 g?
