Oxidation: The gain of oxygen or the loss of hydrogen or the loss of an electron in a species during a redox reaction is called oxidation.
Reduction: The loss of oxygen or the gain of hydrogen or gain of an electron in a species during a redox reaction is called reduction.
(b)
Interpretation:
Using the given data in the given combustion reactions, which species are oxidized and which are reduced, have to be determined and explained.
Concept introduction:
A galvanic cell is an electrochemical cell. Electrochemical cell is a device capable of converting chemical energy into electrical energy or induces chemical energy by electrical energy. In the galvanic cell spontaneous redox reaction takes place. Redox reaction means the reaction in which the oxidation state of the atoms changes due to the occurrence of both reduction and its complementary oxidation reactions. The element under oxidation reaction loses electron whereas the element in the reduction gains electron.
Oxidation: The gain of oxygen or the loss of hydrogen or the loss of an electron in a species during a redox reaction is called oxidation.
Reduction: The loss of oxygen or the gain of hydrogen or gain of an electron in a species during a redox reaction is called reduction.

- The element carbon undergoes many inorganic reactions, as well as being the basis for the field of organic chemistry. Write balanced chemical equations for the reactions of carbon described below. l type='a'> Carbon burns in an excess of oxygen (for example. in the air) to produce carbon dioxide. If the supply of oxygen is limited, carbon will still burn but will produce carbon monoxide rather than carbon dioxide. molten lithium metal is treated with carbon, lithium car bide, Li2C2 , is produced. i>Iron(II) oxide reacts with carbon above temperatures of about 700 °C to produce carbon monoxide gas and molten elemental iron. i>Carbon reacts with fluorine gas at high temperatures to make carbon tetrafluoride.arrow_forwardThe element tin often occurs in nature as the oxide, SnO2 . To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). This produces pure molten tin, with the carbon being removed from the reaction system as the gaseous byproduct carbon monoxide. Write the unbalanced equation for this process.arrow_forwardXenon trioxide, XeO3, reacts with aqueous base to form the xenate anion, HXeO4. This ion reacts further with OH to form the perxenate anion, XeO64, in the following reaction: 2HXeO4(aq)+2OH(aq)XeO64(aq)+Xe(g)+O2(g)+2H2O(l) Identify the elements that are oxidized and reduced in this reaction. You will note that the equation is balanced with respect to the number of atoms on either side. Verify that the redox part of this equation is also balanced, that is, that the extents of oxidation and reduction are also equal.arrow_forward
- A common demonstration in chemistry courses involves adding a tiny speck of manganese(IV) oxide to a concentrated hydrogen peroxide, H2O2 , solution. Hydrogen peroxide is unstable, and it decomposes quite spectacularly under these conditions to produce oxygen gas and steam (water vapor). Manganese(IV) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction. Write the balanced equation for the decomposition reaction of hydrogen peroxide.arrow_forwardYou have probably had the unpleasant experience of discovering that a flashlight battery has gotten old and begun to leak. Is there evidence that this change is due to a chemical reaction?arrow_forwardThe Hall process is an important method by which pure aluminum is prepared from its oxide (alumina, Al2O3 ) by indirect reaction with graphite (carbon). Balance the following equation, which is a simplified representation of this process. m:math>Al2O3(s)+C(s)Al(s)+CO2(g)arrow_forward
- Complete and balance the equations for the following acid-base neutralization reactions. If water is used as a solvent, write the reactants and products as aqueous ions. In some cases, there may be more than one correct answer, depending on the amounts of reactants used. (a) Mg(OH)2(s)+HCl4(aq) (b) SO3(g)+H2O(l) (assume an excess of water and that the product dissolves) (c) SrO(s)+H2SO4(l)arrow_forwardA common experiment to determine the relative reactivity of metallic elements is to place a pure sample of one metal into an aqueous solution of a compound of another metallic element. If the pure metal you are adding is more reactive than the metallic element in the compound, then the pure metal willreplacethe metallic element in the compound. For example. if you place a piece of pure zinc metal into a solution of copper(II) sulfate, the zinc will slowly dissolve to produce zinc sulfate solution, and the copper(II) ion of the copper(II) sulfate will be converted to metallic copper. Write the unbalanced equation for this process.arrow_forwardIdentify each of the following unbalanced reaction equations as belonging to one or more of the following categories: precipitation, acidbase, or oxidationreduction. msp;Fe(s)+H2SO4(aq)Fe3(SO4)2(aq)+H2(g) msp;HClO4(aq)+RbOH(aq)RbCIO4(aq)+H2O(l) msp;Ca(s)+O2(g)CaO(s) msp;H2SO4(aq)+NaOH(aq)Na2SO4(aq)+H2O(l) msp;Pb(NO3)2(aq)+Na2CO3(aq)PbCO3(s)+NaNO3(aq) msp;K2SO4(aq)+CaCl2(aq)KCl(aq)+CaSO4(s) msp;HNO3(aq)+KOH(aq)KNO3(aq)+H2O(l) msp;Ni(C2H3O2)2(aq)+Na2S(aq)NiS(s)+NaC2H3O2(aq) msp;Ni(s)+Cl2(g)NiCl2(s)arrow_forward
