CHEM 101 ACTUAL EXAM QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) ALREADY GRADED A+ NEWEST VERSION If a compound's chemical formula was experimentally determined to be 18, the chemical formula could be: CH4 NH3 H2O PCl5 - Answer H2O Use the periodic table to get the atomic masses of each element. Then you can calculate the formula mass as such: H=1.008×2=2.016 O=15.999×1=15.999 Adding these together we get 18.015, which is approximately 18. The sum...

FINAL EXAM CHM 151 RIO SOLADO M.SCHAAB LATEST UPDATE GRADED A+ What is the difference between an ionic bond and a covalent bond? An ionic bond is formed when one atom transfers electrons to another atom, creating ions that attract each other. A covalent bond is formed when two atoms share electrons. How do you determine the number of valence electrons in an element? The number of valence electrons can be determined by looking at the group number of the element in the periodic t...
