A solution is prepared by diluting 225 mL of 0.1885 M aluminum sulfate solution with water to a final volume of 1.450 L. Calculate the number of moles of aluminum sulfate before dilution.
Consider two hypothetical elements, W and Z. Element W has an electron affinity of ?150 kJ/mol, and element Z has an electron affinity of ?38 kJ/mol.
Its volume has been accurately determine to be 3226.7kj/m. 2.5127 gm benzoic acid are burned in a carorimter the temperatuer rises from 20.84 to 25.67degree. What is the heat capacity of the bomb.
As mentioned in the text, Ni3Al is used in the turbines of aircraft engines because of its strength and low density. Nickel metal has a cubic close-packed structure with a face-centered cubic unit cell
After the resulting reaction was complete, back titration required 10.40 mL of 0.1212 M NaOH. Assuming that the tablet contained only calcium carbonate and an inert binder calculate the mass of calcium carbonate and mass percent of calcium carbona..
what would the final common temp be assuming no heat loss? Use Cp for ethanol = 60.0 J K -1 mol -1 and Cp for Copper = 0.380 J K -1 g -1.
How many moles of CO2 form when all of the butane is the lighter burns. How many molecules of gas form when the butane in the lighter burns completely
Use the density of copper (8.95 g/cm3) and its molar mass (63.55 g/mol) to calculate an approximate atomic radius for copper.
The standard free energy of activation of a reaction X is 89.4 kJ mol-1 at 298 K. Reaction Y is one million times faster than reaction X at the same temperature.
A solution is prepared by dissolving 10.8g ammonium sulfate in enough water to make 1.00 mL of stock soultion. A 10.00 mL sample of this stock solution is added to 50.00mL of water. Calculate the concentration of ammonium ions and sulfate ions in ..
What is the concentration of the HNO3 solution? (b) How many moles of NaOH were in excess after the first addition?
A young child grows rapidly, with high levels of cell division and high energy requirements. If you were planning the child's diet, which food groups would you emphasize, and why? Which good groups would you deemphasize, and why?
What should you observe happening to the gas produced: A) If the concentration of the acid HCl is increased? B) If the solid calcium carbonate is in powder form
