Identify the unknown particles X and X' in the following nuclear reactions. (In parts (a) and (b), enter only the missing product or reactant.) a) x + 4 2He → 24 12Mg + 2 1 0n
b) 235 92U → 90 38Sr + X + 2 1 0n

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)
