1. Determine the sum of the group numbers for the atoms in each of the molecules below and see if your answer still agrees with the Rule of Eight.MoleculeSum of Group #'sRule of 8?NH3 (ammonia)CaCl2 (calcium chloride)Al2O3 (aluminum oxide)2. Use the Rule of Eight to write a chemical formula by determining how many atoms of one element would be necessary to combine with how many atoms of another element to form a particular molecule. (Fill in the subscript for each product.) You should be able to do any molecule I give to you in the future.1 Mg + ______Cl  MgCl___ (magnesium chloride)2 H + 1 S + ____ O  H2SO___ (sulfuric acid)1 C + ___ H  CH ___ (methane)2 H + ___ O + 1 C  H2CO___ (carbonic acid)In Conclusion, chemists explain this Rule of Eight phenomenon by saying that all atoms (except for the inert gases) have incomplete outer electron shells. When atoms react with each other, each atom ends up with a complete outer shell of 8 electrons. They call this principle,…
