Chemistry Final Exam (Answered) Oxidation Rules Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) -Mg=0,H2=0, C=0 Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion -Mg^2+=+2, Na^+=+1, O^2-=-2 Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. Rule 4: The oxidation numb...

NSCI 175 Final Exam Review. Questions with complete Answers 2023 Explain Why Progress in science is often slow -Because experiments take time and the process of observation, replication, interpretation, and verification is exhaustive. It also takes time to get published and for the new information to become widespread. Explain the Reductionist Approach: - How is the Approach? Is the process of breaking down the enormous problem of understanding how the brain works into smaller pieces ...

Membrane PotentialDo all living cells have a membrane potential? - correct answer UMM YESH What is a membrane potential? - correct answer Difference in charge inside/outside the cell membrane What is electrical potential? - correct answer When opposite charges are separated they have the potential to do work if allowed to come together What 2 ways can electrical force increase? - correct answer Quantity of charge, decreased charge separation What is the RMP of a typical neuron? - cor...
