Explain the atomic orbitals of two iodine atoms combine to form the I2 molecule. Utilize the periodic table to find out the orbitals that overlap to form the I2 molecule example for the hydrogen atom the 1s orbitals overlap as well as the noble gas that has the electron configuration analogous to the electron configuration of each bonded iodine atom.For instance, to enter the atomic orbitals of two fluorine atoms that unite to form an F2 molecule as well as the corresponding noble gas, you would enter 2p, Ne.
Enter the symbol for the orbitals that overlap (example for H2 enter 1s) as well as the chemical symbol of the noble gas separated by a comma.
During World War II, tritium (3H) was a component of fluorescent watch dials and hands. Assume you have such a watch that was made in January 1944. If 16% or more of the original tritium was needed to read the dial in dark places,
Identify the nuclide produced when fluorine-18 decays by positron emission:18/9F->0/1e+ Identify the nuclide produced when thallium-201 decays by electron capture: 201/81Tl+0/-1e->0/0radiation+
Write a molecular equation for the precipitation reaction (if any) that occurs when the following solution are mixed. How do you convert these over and please show steps.
CO(g) + 2H2(g) = CH3OH(g) , what is the equilibrium constant? , where CH3OH = 0.0412 atm, H2 = 0.274 atm, CO = 0.914 atm.
Use the following data to calculate the equilibrium constant K for the following reaction at 78?C: 2Br?(aq)+Cl2(g)?Br2(l)+2Cl?(aq) You may assume that ?H? and ?S? are independent of temperature.
