The radioactive isotope 247 Bk undergoes a series of alpha-particleand beta particle productons, taking bk-247 through manytransformations to end up as 207pb. in the complete decay series,how many alpha P and how many beta P are produced? indicateintermedidiate nuclides.How do you do this without knowing the stages, etc? Ihave looked thru two textbooks, and there is not a single exampleof how to do this.
1000g of Na2HPO4 is dissolved in 100mL of water. using mass balance and charge balance deterimne the pH of the resulting.

When potassium carbonate is added to the remaining solution, a precipitate occurs. Which ions were present in the original solution? Write net ionic equations for the formation of each of the precipitates observed.
The pressure of hydrogen fluoride in Agent P's lab is lower than expected and rises more quickly as the temperature is increased than the ideal gas law predicts. Suggest an explanation. Are we dealing with a real or ideal gas
Determination of the composition of a mixture You will be given a multi-component mixture and will be required to determine (and confirm) the %composition of the mixture, obtain a sample of each component and to verify its purity and identity.
