The radioactive potassium- 40 isotope decays to argon- 40 with a half-life of 1.2 ×10^9 years. (a) Write a balanced equation for the reaction. (b) A sample of moon rock is found to contain 18 percent potassium- 40 and 82 percent argon by mass. Calculate the age of the rock in years. (Assume that all the argon in the sample is the result of potassium decay.) | Numerade

Problem 5: Argon gas has several industrial uses, including arc welding and steel making. Argon is nonflammable and nontoxic, so it can be kept at room temperature (T = 20°C). Companies can buy Argon gas in cylinders, which are kept at a pressure of P = 216 psi. In this problem, you may assume that the ideal gas law still holds.Part (a) How much average kinetic energy (in KJ) does each atom of the Argon gas in the cylinder have? KJ = 6.1E-21 (Correct?)Part (b) If the volume of this cylinder is
