Assuming that all the other quantum numbers can take only the values possible in our world and that the Pauli esclusion principle applies, give the following.
1. The new electron configuration of neon.
2. The atomic number of the element with a completed n-2 shell.
3. The number of unpaired electrons in fluorine.
How much water must be added to 534. mL of 0.180 M HCl to produce a 0.135 M solution? (Assume that the volumes are additive.)
You prepared a 0.250 M solution by diluting 8.45(+-0.04)mL of 28.0(+-0.5)mL wt.%NH3 (density=0.899(+-0.003)g/mL up to 500.0(+-0.2)mL. Find the uncertainty in 0.250 M.
Natural K consists of 2 stable isotopes 39K(93.10%) and 41K(6.88%) and one radioactive isotope 40K (0.0118%, t1/2 = 1.27x109 years).
The analysis was completed by titrating the excess acid with 11.37 mL of 0.1080 M NaOH. How many of these tablets represent a proper dose for patients whose weight is 100 lb (assume that 1 pound, lb, is 0.45 kg).
Calculate the volume of 0.540 M sodium hydroxide solution contains 11.5 grams of sodium hydroxide?
chemical potential energy from rotating turbines into thermal energy. B) electrostatic energy from rotating turbines into chemical energy
The partial pressure of CO2 inside a bottle of soft drink is 4.0 atm at 25°C. The solubility of CO2 is 0.12 mol/L. When the bottle is opened, the partial pressure drops to 3.0 * 10-4 atm. What is the solubility of CO2 in the open drink? Express yo..
A small cube of aluminum measures 15.6 mm on a side and weighs 10250 mg. what is the volume of this cube in cubic cm? how would I find this out.
In the electron transport chain, electrons from FADH2 are eventually used to reduce O2 into H2O. Experimentally, the proton motive force created by this process will generate 2 ATP molecules from ADP and Pi, using ATP synthase.
How many grams of dry NH4Cl need to be added to 2.10 L of a 0.500 M solution of ammonia, NH3 , to prepare a buffer solution that has a pH of 8.76? Kb for ammonia is 1.8*10 ^-5.
Suppose the calorimeter for this experiment had been made of a heat-conducting material (such as metal) rather than plastic foam, so that the portion of heat energy lost to the calorimeter itself was larger and could not be ignored
If 6.73 g of Na2CO3 is dissolved in enough water to make 250. mL of solution, what is the molarity of the sodium carbonate?
