Alab has 60 ml of a solution of uranium sulfate dissolved in water. based on the work done by the curies, how can the amount of radioactivity be reduced? by adding more water to dilute the solution by removing sulfate ions by adding heat to raise the temperature by removing uranium ions

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
