1. Calculate the atomic mass of the element X and identify the element from the periodic table knowing that it has the following isotopes: 54X (mass: 53.940, abundance: 5.9%), 56X
(mass 55.935, abundance: 91.72%) and 58X (mass: 57.933, abundance: 0.28%)

Which of the following methods uses the decay of atomic particles in an object to find its exact age? a. fossil dating b. geologic dating c. radioactive dating d. relative dating

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Analyze how limestone is weathered and identify the features that are formed as a result of this dissolution
