Redox (reduction-oxidation) reactions are those in which the oxidation states of the reactants change. Check All That Apply. However, an oxidizing agent oxidizes something else, and gets reduced, therefore gaining electrons. H+ Is Reduced To H2. Think of it this way when you are doing and Oxidation Reduction lab you have two solutions that are connected with a salt bridge that it for the flow of the ions and you have two pieces of metal in each solution connected by a wire to each other. Select all the statements that correctly describe the relationship between... Why Join Course Hero? In fact, much of our technology, from fire to laptop batteries, is largely based on redox reactions. Which of the following options correctly describe a precipitation reaction? In the ion-electron method, the unbalanced redox equation is converted to the ionic equation and then broken […] Question: Select All The Options That Correctly Describe How Energy Is Involved In Chemical Reactions. Select all that apply. Course Hero has all the homework and study help you need to succeed! The reactants are insoluble precipitates. Which of the following statements correctly describe aerobic respiration? This occurs because in such reactions, electrons are always transferred between species. H' Is The Oxidizing Agent. (b) An example of a catabolic reaction is converting starch to glucose. The Oxidation half-reaction and the Reduction-half reaction occur simultaneously. Question: Select All The Statements That Correctly Describe The Following Redox Reaction, Which Is Given As A Molecular Equation: Mg (s)+ 2HCI (aq) Mgc2(a)H2 (g) Check All That Apply. (Select all that apply) (a) The energy released in anabolic reactions can be used to synthesize ATP. Redox reactions are all around us. Third option is the correct one. Mg2+ Is The Reducing Agent. Step 4: Multiply each half-reaction by a constant so both reactions have the same number of electrons. Learn how to use the half-reaction method to balance equations for redox reactions occurring in acidic and basic solution. Step 3: Balance the half-reactions charges by adding electrons to the half-reactions. The electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.The electron transport chain is built up of peptides, enzymes, and other molecules. Cl-is Reduced To Cl Do You Know The Answer? Select ALL that are correct. When an element is oxidized, it loses electrons. This type of reaction often occurs in aqueous solution. Answer to Which one of these equations describes a redox reaction? The electrons should cancel out, leaving a balanced complete redox reaction. Chemists have developed an alternative method (in addition to the oxidation number method) that is called the ion-electron (half-reaction) method. The reactants are insoluble precipitates This type of reaction usually involves ionic compounds. This type of reaction forms one or more insoluble products. Select all that apply Check all that apply. Redox equations are often so complex that fiddling with coefficients to balance chemical equations doesn’t always work well. This is the basis of redox reactions. B. Step 5: Add the two half-reactions together. Which of the following options correctly describes a precipitation reaction? But when an element is reduced, it gains electrons. Learn how to use the half-reaction method to balance equations for redox reactions occurring in acidic and basic solution. Meanwhile, a reducing agent reduces something else, and gets oxidized in the process, losing its own electrons. Mg Is Oxidized To Mg ? A.
