The radius of the Zr atom is 145 picometers. However the radius of the element directly below it, Hf, is only 144 pm. Think about this and select the following statements that are true. 1. This is the expected periodic trend for atomic radius. 2. This is not the expected periodic trend for atomic radius. 3. Based on the radii, the effective nuclear charge experienced by the valence electrons must slightly greater for Zr than for Hf. 4. Based on...

Chlorine gas reacts with fluorine gas to form chlorine trifluoride. Cl2(g) + 3 F2(g) --> 2 ClF3(g) A 2.00-L reaction vessel, initially at 298 K, contains chlorine gas at a partial pressure of 337 mmHg and fluorine gas at a partial pressure of 729 mmHg. Identify the limiting reactant and deter- mine the theoretical yield of ClF3 in grams. I got 4.84g ClF3 for this problem, but the textbook answer is 2.84g. Can anyone tell me where I went wrong,...
