CSU LIFE 102 FINAL EXAM ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS Phosphorus has an atomic number of 15. This tells us that... - Answer -there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer -True An e- in a hydrogen atom exists in the first valence shell. The valence eof Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer -the valence e- of aluminum, bc higher e- shells have higher energy A covalent bond is likely to be polar when - Answer -one atoms sharing e- is much more electronegative than the other atom What property of water allows the formation of water droplets? - Answer -Cohesion How many molecules are present in one mole of the hydrocarbon, Cyclohexane (c6h12) - Answer -6.02x 10^23 Scientific theory - Answer -an explanation about the natural world is based on facts, laws, and widely tested hypotheses Processing energy, growing, reproducing, evolutionary adaptations, and more are examples of Need assistance on Online classes, Exams & Assignments?

Which does NOT contribute to the formation of this diversity? - Answer -can rotate around double bonds correct: carbon chain branching, carbon chain length, ability to form rings, double bond position (CANT ROTATE AROUND DOUBLE BONDS) Structural Isomers Need assistance on Online classes, Exams & Assignments?
