Element X has two isotopes. If 98.90% of the element has an isotopic mass of 12.00 amu, and 1.10% of the element has an isotopic mass of 13.01 amu. Calculate the average atomic mass for this element and identify the element. Use a stylus, pencil (if using a chromebook), or finger to solve the problem in the space below. (1 point work, 1 point answer, 1 point sig figs, 1 point units, and 1 point for correct element identified)

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
