Redox reactions Guides d'étude, Notes de cours & Résumés

Metabolic processes are associated with chemical reactions such as (1) redox reactions, (2) dehydration condensation reactions, (3) dehydration reactions and (4) hydrolysis reactions. Redox Reactions involve the transfer of electrons called oxidation-reduction reactions (commonly called redox reactions). This reaction involves two steps. First, A redox reaction's first step. the oxidation step in which an electron (or hydrogen atom) is lost from a substrate. Second, the lost electron is t...

CEM 142 Exam 3 MSU Questions and Answers Rated A+ What do you know about reactions? (make a list) -Atoms are conserved. They are only re- arranged. -Properties of products are emergent (not a mixture of the reactants properties). -Reactions can be classified by the type of reaction (how it occurs). -Reactions are always accompanied by an energy change (can be exo and endo) that results from changed in interactions (bonds and IMFs) in the reactants and products. -Reactions are alway...

What is the relationship between photosynthesis and cell respiration? Be sure to include the overall chemical equation for both reactions correct answer: The relationship between cell respiration and photosynthesis is an inverse relationship, that both sides are opposite each other. In photosynthesis, CO2 is taken in, and O2 is excreted, while in cellular respiration, C02 in excreted, and O2 is needed for the reaction to commence. Distinguish between oxidation and reduction. Why are these p...

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...
