A sample of iron was heated to 148.0°C, then placed into 368 g of water at 23.6°C. The temperature of the water rose to 27.2°C. How many grams of iron were in the sample
Write the chemical equation for the following reaction: Add 1mL of 6M HCl to 1mL of 0.5M Na2SO4. Add a few drops of 1M BaCl2. How do your incorporate the BaCl1 into the chemical equation
Write balanced molecular, total ionic and net ionic equations for the reaction of aqueous copper (II) sulfate and aqueous sodium sulfide. Be sure to include proper phase labels.
For atomic iodine, determine the degeneracy (which arises from the spin multiplicity) of the first two electronic states. Both are derived from the same S-L term symbol, using spin-orbit (J) coupling. The second state lies 7580 cm-1 above the firs..
