1. In the nuclear transmutation represented by 23994Pu(42He,10n)?, what is the product?
uranium-242uranium-243curium-245uranium-245curium-242
2. The cloth shroud from around a mummy is found to have a 14C activity of 8.8 disintegrations per minute per gram of carbon as compared with living organisms that undergo 15.2 disintegrations per minute per gram of carbon.
From the half-life for 14C decay, 5715 yr, calculate the age of the shroud

Calculate the number or calories of heat energy required for warming 34.6g of water from 18.9 celsius to 29.9 celsius
When 33.4 mg of a compound is dissolved in 10.0 ml of water at 25 C the solution has an osmotic pressure of 558 torr. Calculate the molar mass of the compound.
Describe how the results from this control experiment would be incorporated into the data analysis to the correct for this error.
Differentiate between the dfferent bond types of orbital overlap required to obtain a sigma bond and pi bonds
Which of the seven cations will be the hardest to detect (same anions as above), Why do you think this? If two or more are possible explain why.
The numbers above are also the only numbers I am given. I do not have delta G's of molar G's. If you have an answer that solves for the G's and shows me step by step how to solve the problem, you will get five stars.
